CSRF Attacks in a nutshell
10 Apr 2016 | SecurityCross Site Request Forgery (CSRF) is something you might have come across if you’re into web development. Even if you’re not, its always good to have an idea about how you might be vulnerable to it.
I’ve been working on GNOME Music and ownCloud’s music app lately and a particular feature required exposing an internal endpoint. This post is largely inspired by ownCloud’s sophisticated design to prevent CSRF attacks.

Imagine a scenario where you’re an active user of vulnerablehost.com
, a
music player which uses an endpoint like
http://vulnerablehost.com/add/music/?url=<url_to_file>
to enqueue music to
the playlist. While relatively unharmful at first, what if you happen to visit
another site evilintents.com
which hides among other things, something as
frivolous as
<img src="http://vulnerablehost.com/add/music?url=<evil hosts music taste>">
Your browser would just pass on the request and append evilhost’s music to
your playlist. You might wonder if vulnerablehost.com
could have made the endpoint
accessible only via a POST request to circumvent the attack. The only problem
is, crafty evilintents.com
can probably fool you into submitting a form with
the target pointing to the former

<form action="http://vulnerablehost.com/add/music" method="POST">
ID
<input name="id" type="text">
<input type="submit">
<input type="hidden" name="url" value="<evil hosts music taste>">
</form>
To understand the possible implications of the attack, reconsider
vulnerablehost.com
as your banking website with an endpoint to transfer funds
to a benficiary.
Prevention
Fortunately, there is a way to prevent CSRF attacks on endpoints by requiring
requests to contain data that only you, the client and the server would know
and there is no way for evilintents.com
to figure it out. This is often
referred to as a CSRF token, which is hidden along with your POST request and
enables nonvulnerablehost.com
to ensure the requests are not send
inadvertently.

<form action="http://nonvulnerablehost.com/add/music" method="POST">
URL:
<input type="text" name="url">
<input type="hidden" name="csrftoken" value="randomvalueknownbyserver">
</form>
In the above scenario, there is no way for evilintents.com
to guess the value
of csrftoken
that is checked on every form submission at
nonvulnerablehost.com
, thereby rendering CSRF attacks useless :) Many
web frameworks are bundled with CSRF Middlewares that do the check on every
POST request automatically and mitigate the attack.
Conclusion
Theoretically, CSRF attacks are not hard to defend against, but practically developers often overlook possible situations. It’s not hard to look around for possible CSRF vulnerabilities. While attacks are rarely in jest, if you’re a BITSGian, logged in via Cyberoam, chances are you’ll have to login again ;)

An initiative by us which is complimentary to the RTE act. Sponsored by the Narain Sri Foundation, we see The Khwahishein School as an opportunity to make underpriviliged children school-ready so as to reduce drop out rates and give them a fair chance to become educated and successful citizens. With an emphasis on overall education, we are striving to imbibe good morals and practices in our students in these crucial years of physical and mental development.
One of our oldest projects, it helped us bring happiness into many people’s lives through the simple act of fulfilling their small wishes. From owning a toy to wearing a new shirt, every wish we fulfilled led to many smiling faces and many contented souls..
These projects were started by us in the school run by Rashtriya Hit Sewa Sangathan (RHSS). In these projects, we collaborate with schools that are being run for underprivileged children to take overall development sessions. These sessions include inculcating in them the importance of dreams, and how can they achieve their goals, safety and also to promote health and hygiene amongst the kids. Araatrika is the project for underprivileged adolescent females, with the focus being laid upon their health. Sammaan is the project wherein the focus stays upon inculcating equality for both the genders, to teach kids how to respect the other gender.
It is our annual donation drive, wherein we collect essential commodities from donors and identify sections of people who need them. We then proceed to the distribution of collected commodities to the people in dire need of them. We have recently helped resettle Kashmiris who were displaced due to the rampant flood in J&K though this project by donating food and clothes in ample amounts.
Every month, we decide upon a theme to identify a social issue and work on it. In the month of March, we decided to focus on enabling people suffering from physical and mental disabilities. We made multiple visits to institutions like Deepashram , which cater to such individuals and tried to address the issues faced by them. In addition to that, we organised some fun activities for them to enjoy. This monthly theme format allows us to cater to a wider range of society in an efficient manner and allows us to identify new areas where we can be of assistance.

Railway expansion: Nigerian army relocates units to Epe
by Agency ReportThe Nigerian Army has relocated some of its units and formations located at Yaba to Epe to pave way for the expansion of railway project in Lagos State.
The units relocated are the 81 Division Base Ordnance Depot, printing press and tailoring factory.
The Chief of Army Staff, Lt.-Gen. Tukur Buratai, during the groundbreaking for the construction on Saturday, disclosed that the relocation would lead to enhanced military presence in the area.
“We have to come back because of the Federal Government’s new drive to modernise the transport sector by establishing new standard dual gauge railway system for our country.
“I want to use this opportunity to appreciate the cooperation of the honourable minister of transportation, in facilitating the prompt approval and release of fund that has made this a laudable project a reality.
“The minister was very supportive of the Nigerian army throughout the negotiation for the movement of this unit out of Yaba for the speedy completion of negotiations and of course the funding,” he said.
The Army Chief also commended the paramount ruler of Epe, Oba Kamorudeen Animashaun, for his continuous support for Nigerian army in its operations and the relocation of the unit base to the area.
The Minister of Transportation, Mr Rotimi Amaechi, represented by Deputy Director, Rail Transport Services, Mr Barry Odii, said that the ministry decided to support army because of its cooperation in relocating the units from Yaba railway corridor.
“The groundbreaking ceremony for the construction of new office and a residential accommodation, as well as other facilities for 81 Division Ordinance Corps, will mark a significant milestone in the history of transportation sector and the country at large.
“It is an exhibition of excellent intercourse between the Nigerian army and the Federal ministry of transportation,” he said.
The Chairman, Epe Local Government Area, Mr Doyin Adesanya, said that the people of Epe were happy with the coming of the military to the area.

I believe all you'd need is to replace the blockhash with the VerusHash block hash. To do that, you'd want to use haraka* and verus_hash.* from the crypto directory, and to move SerializeVerusHash and VerusHashWriter from hash.h in the src directory to your hash.h. You should also copy the hash function pointer and selection from CBlockHeader to support portability and performance and make it easier to port. Then, at runtime, just make sure to call CVerusHash::Init() and select your hash function to set the function pointer. Of course, with a height dependent change, you may want the main hash function for CBlockHeader to just select between what you use now and VerusHash. I think that would cover everything.

This is an Application Programming Interface (API) that delivers a Linked Data distribution of the Australian Hydrological Geospatial Fabric (the Geofabric).
This distribution of the Geofabric doesn't add any new information to the Geofabric other than associating classes of data within it with classes in the HY Features ontology.
This tool was developed for the Location Index project involving CSIRO & Geoscience Australia which implements a series of national spatial Linked Data datasets for Australia.
This API is facilitated by the pyLDAPI tool, working on top of Python's Flask web framework, which, with custom Python code, reads a slightly customised data feed of the Geofabric's spatial data Geofabric data from a Web Feature Service (WFS) which emulated the Bureau of Meteorology's Geofabric WFS (see The BoM Geofabric's Web Services documetation.
The code for this application is available in a repository at:
The conversion of the Geofabric from its original WFS form into Linked Data relies on the Geofabric Ontology which models part of the Geofabric in a Semantic Web manner. That ontology, in turn, relies on the HY_Features model, originally developed by the CSIRO/BoM WIRADA collaboration.
This API is developed by:
CSIRO's Environmental Informatics Group within CSIRO Land & Water.

While problems on colored point sets have been receiving substantial attention, colored line arrangements have not been much explored. However, despite the duality between the two type of problems, some questions are only natural or appealing in the second scenario.
In this talk we mention some previous research on the topic, and describe several recent results that we have proposed and coauthored, coming from [1,2,3].

EPL: Mourinho in winning starts as Spurs beat West Ham
Jose Mourinho enjoyed a winning start as Tottenham manager with a 3-2 London derby triumph over West Ham at London Stadium.
First-half goals from Son Heung-min and Lucas Moura and a third from Harry Kane four minutes after the break gave Tottenham their first Premier League away win since 20 January.
It was about as comfortable as Mourinho could have hoped for after a tumultuous week, in which he replaced Mauricio Pochettino, who was sacked by Daniel Levy less than six months after guiding the club to the first Champions League final in their history.
The result piles pressure on West Ham boss Manuel Pellegrini, whose side have now collected two points from their last seven games.

Under-fire keeper Roberto made an error for Son’s opener and the hosts were booed off at half-time.
Late goals from substitute Michail Antonio and Angelo Ogbonna gave the final scoreline a flattering look, but the result made a mockery of an ill-advised post from West Ham’s social media team following Mourinho’s appointment, highlighting previous difficulties the 56-year-old has endured at London Stadium.

As explained in the email, Phase 1 will permit the in-person return of a limited number of graduate and undergraduate students. The majority of the students selected to return for in-person classes will be those who must meet accreditation or require essential on-campus equipment or facilities that are otherwise inaccessible. Undergraduate students will be notified of their status as a returning student by Aug. 4, and graduate students will be notified by Aug. 7.
However, a number of students expected OU’s administration to have a different response regarding the coronavirus.
Aubrey Roese, a senior studying psychology and social work, believed fall semester would be held entirely in-person, even if that wasn’t the safest decision.
“I expected OU to go back fully. I thought this because I thought they would prioritize getting money from things like dorms, meal plans, etc. over the safety of the students.”—Aubrey Roese, a senior studying psychology and social work
“I expected OU to go back fully,” Roese said in an email. “I thought this because I thought they would prioritize getting money from things like dorms, meal plans, etc. over the safety of the students.”
Many other major universities, such as Ohio State University, are also adapting their schedules and plans for the Fall Semester to encourage maximum safety for students. While this transition to online classes does help ensure COVID-19’s rate of infection won’t increase as dramatically when students return to campus, students are still worried about the quality of their online courses.
Some students, such as Yang Chen, a senior studying finance, marketing and graphic design, already intentionally avoid taking online courses due to their lower quality.
“The instructors of online classes are generally less willing to send emails frequently to help students, based on my experiences, so I never take online classes unless I have no choice,” Chen said in an email, noting that many professors of online courses often will reply to emails just once a day. “And I do not feel like we get high-quality results … Some classes are not designed to be remote. There is knowledge, discussion and experiments (in) which learning from online is kind of the worst experience. If OU moves some of the classes to remote, the tuition for these classes needs to be cut.”
This is a strong fighting point for many students, who agree that online classes tend to be lower quality and so tuition should be lowered for those individual courses. Online classes have traditionally been cheaper than in-person classes at OU, so many students expect the cost of courses to be lowered if they are required to be virtual.
Irene Kent, a junior studying strategic communication, fully believes the prices of both dorms and tuition should be reduced.
“The quality of education is not the same if classes are online, and even if we do have in-person classes, the amount of people in the classroom will be limited,” Kent said in an email. “In my opinion, collaborating with classmates is one of the best ways to learn, but that most likely will not be an option due to the risks that come along with it. There are going to be a lot of restrictions, and people don’t like restrictions. Not reducing tuition or the price of dorms will cause a lot of frustration and conflict between the University and its students.”
While OU is taking large steps to ensure the safety of its students, such as requiring the constant wearing of masks and decreasing the sizes of classes that are in-person, requiring most classes to be online will be a detriment to many.
“I would say that OU’s response could definitely impact my future career,” Kent said.  If we go completely online, students will suffer and miss out on important opportunities.”

It is my belief that the ability to communicate and the ability to learn sets the stage for personal growth and success. Though both skills must be worked for, they can be enhanced, and at times expedited by reading books.
The following is a chronicle of literary works (not all about design) that I feel, have defined me and helped me to grow as both a human and a designer. They appear in the order in which they have been read, with the first element in the list having been read most recently.

Here we go. October 12, 2014
I'm excited! I wish Phase 1 could start right now. It is clear from the video that they are constantly trying new things and I want to see that in action. This is clearly an educational situation unlike anything I have experienced before and want to see what the heck is going on.
I'm nervous because of course I don't feel smart enough, or fast enough or experienced enough but I'm gonna show a little faith and keep grinding through Phase 0 and see what happens.
Woo-hoo!

Next: Error Detection Time in Safe Calls, Previous: Argument Mismatch Detection, Up: Argument Mismatch Detection
A call is a safe call if each of the following is either safe code or system code (other than system code that results from macro expansion of programmer code):
the call.
the definition of the function being called.
the point of functional evaluation
The following special cases require some elaboration:
If the function being called is a generic function, it is considered safe if all of the following are safe code or system code:
its definition (if it was defined explicitly).
the method definitions for all applicable methods.
the definition of its method combination.
For the form (coerce x 'function), where x is a lambda expression, the value of the optimize quality safety in the global environment at the time the coerce is executed applies to the resulting function.
For a call to the function ensure-generic-function, the value of the optimize quality safety in the environment object passed as the :environment argument applies to the resulting generic function.
For a call to compile with a lambda expression as the argument, the value of the optimize quality safety in the global environment at the time compile is called applies to the resulting compiled function.
For a call to compile with only one argument, if the original definition of the function was safe, then the resulting compiled function must also be safe.
A call to a method by call-next-method must be considered safe if each of the following is safe code or system code:
the definition of the generic function (if it was defined explicitly).
the method definitions for all applicable methods.
the definition of the method combination.
the point of entry into the body of the method defining form, where the binding of call-next-method is established.
the point of functional evaluation of the name call-next-method.
An unsafe call is a call that is not a safe call.
The informal intent is that the programmer can rely on a call to be safe, even when system code is involved, if all reasonable steps have been taken to ensure that the call is safe. For example, if a programmer calls mapcar from safe code and supplies a function that was compiled as safe, the implementation is required to ensure that mapcar makes a safe call as well.

The Chennai Metro, officially Chennai Metro Rail Limited (CMRL), is a rapid transit system serving the city of Chennai, Tamil Nadu, India. The system commenced revenue service in 2015 after partially opening during the first phase of the project, which consists of lines along two corridors covering a length of 45.1 kilometres (28.0 mi). The Government of India approved the plan for 9 kilometres (5.6 mi) extension in 2016.
The construction began in June 2009 and the first stretch covering the seven stations from Koyambedu to Alandur over a distance of 10 kilometres (6.2 mi), began operation on 29 June 2015.

In this series, we’re instrumenting a Phoenix app and sending metrics to StatsD with the help of Elixir and Erlang’s Telemetry offerings. A brief overview of what we’ll cover:
- Part I: Telemetry Under The Hood
- Part II: Handling Telemetry Events with
TelemetryMetrics
+TelemetryMetricsStatsd
- Part III: Observing Phoenix + Ecto Telemetry Events
- Part IV: Erlang VM Measurements with
telemetry_poller
,TelemetryMetrics
+TelemetryMetricsStatsd
In Part I we’ll start out by setting up a basic, DIY Telemetry pipeline and examining how Erlang’s Telemetry library works under the hood. Then, in Part II we’ll take advantage of the TelemetryMetrics
and TelemetryMetricsStatsd
libraries to respond to Telemetry events by formatting them as metrics and reporting those metrics to StatsD. In Part III, we’ll look at the powerful instrumentation that Phoenix and Ecto offer out-of-the-box via Telemetry events executed in source code. Lastly, in Part IV, we’ll leverage the telemetry_poller
Erlang library to take Erlang VM measurements and emit them as Telemetry events, which our Telemetry pipeline can then observe and report on.
Introduction
In this post we’ll discuss why observability matters and how Telemetry helps us treat observability like a first class citizen in Elixir projects. Then, we’ll hand-roll our own instrumentation pipeline using Telemetry and StatsD. We’ll wrap up with a look under the hood of the Telemetry library and set ourselves up for Part II of this series, in which we leverage the Telemetry.Metrics
library for even easier instrumentation and reporting.
Observability Matters
In the immortal words of Charity Majors, observability means asking ourselves:
can you understand what is happening inside the system — can you understand ANY internal state the system may get itself into, simply by asking questions from the outside?
Anyone who has spent hours (days?) debugging a production issue that they can’t replicate locally, relying mostly on guesswork and institutional knowledge knows what it costs to lack this ability.
Many of us have come to treat this situation as perfectly natural–we’ve come to accept this frustration as part of the job of being a software engineer. We treat observability like something that is out of our hands, or an afterthought–a “nice to have” after the main target of building that new feature or shipping the MVP are hit.
The traditional split between “web developers” and “dev-ops engineers” has lulled us into believing that observability is not the responsibility of the web dev. In the past, it may have been the case that ensuring system observability required a specialized set of skills, but this is increasingly not true of the world we live in.
With third-party tools like Datadog, Splunk and Honeycomb, and libraries like Telemetry, web developers are empowered to treat observability like the first class citizen it is. To paraphrase Charity Majors (again), in today’s world we can instrument our code, watch it deploy, and answer the question: “is it doing what I expect?”. In this way, we can build systems that are “both understandable and well understood”.
Telemetry Gives Us Visibility
Telemetry is an open source suite of libraries which aims to to unify and standardize how the libraries and applications on the BEAM are instrumented and monitored. How does it work?
At the core of Telemetry lies the event. The event indicates that something has happened: an HTTP request was accepted, a database query returned a result, or the user has signed in. Each event can have many handlers attached to it, each performing a specific action when the event is published. For example, an event handler might update a metric, log some data, or enrich a context of distributed trace.
Telemetry is already included in both Ecto and Phoenix, emitting events that we can opt-in to receiving and acting on accordingly. We can also emit our own custom Telemetry events from our application code and define handlers to respond to them.
The Telemetry events emitted for free from Ecto and Phoenix mean standardized instrumentation for all apps using these libraries. At the same time, the interface that Telemetry provides for handling such events and emitting additional custom events empowers every Elixir developer to hit observability goals by writing and shipping fully instrumented code with ease.
Now that we understand why observability matters and how Telemetry supports observability, let’s dive into the Telemetry library!
Using Telemetry in Elixir
First, we’ll take a look at how to set up a simple reporting pipeline for custom Telemetry events in our Phoenix app. Then, we’ll take a look under the hood at the Telemetry library to understand how our pipeline works.
Getting Started
You can follow along with this tutorial by cloning down the repo here.
- Checking out the starting state of our code on the branch part-1-start
- Find the solution code on the branch part-1-solution
Our Phoenix app, Quantum (get it?), is pretty simple–users can sign up, log in and click some buttons. Awesome, right? Really this dummy app just exists to be instrumented so it doesn’t do much, sorry.
Overview
To get our pipeline up and running we will:
- Install the Telemetry library
- Execute a Telemetry event
- Define an event handler module and callback function
- Attach the event to the handler
Let’s get started!
What We’re Instrumenting
We’ll start by picking a workflow to instrument. But first…
A Note on Metrics
In order for us to truly have observability, we need more than visibility into predefined metrics. Metrics are useful for creating static dashboards, monitoring trends over time and establishing alerting thresholds against those trends. Metrics are necessary for us to monitor our system, but since they are pre-aggregated and pre-defined, they don’t achieve true observability. For true observability, we need to be able to ask and answer any question of our running system. So, we want to track and emit events with rich context. Instead of establishing a metric for a specific web request and tracking its count and duration, for example, we want to be able to emit information describing any web request and include rich descriptors of the context of that request–its duration, the endpoint to which it was sent, etc.
Although we want to emit an event for every web request, we’ll start by picking just one endpoint to instrument.
Our Custom Telemetry Event
Let’s emit a Telemetry event every time a user hits the /register
route and visits the sign up page.
Step 1: Installing Telemetry
First, we’ll install Telemetry and run mix deps.get
:
# add the following to the `deps` function of your mix.exs file
{:telemetry, "~> 0.4.1"}
Now we’re ready to emit an event!
Step 2: Executing a Telemetry Event
To emit a Telemetry event, we call :telemetry.execute/3
. Yep, that’s right, we call on the Erlang :telemetry
module directly from our Elixir code. Elixir/Erlang inter-op FTW!
The execute/3
function takes in three arguments–the name of the event, the measurements we’re using to describe that event and any metadata that describes the event context.
We’ll emit the following event, with the name [:phoenix, :request]
, from the new
function of our UserController
.
Our event:
defmodule QuantumWeb.UserController do
use QuantumWeb, :controller
alias Quantum.Accounts
alias Quantum.Accounts.User
def new(conn, _params) do
start = System.monotonic_time()
changeset = Accounts.change_user(%User{})
:telemetry.execute([:phoenix, :request], %{duration: System.monotonic_time() - start}, conn)
render(conn, "new.html", changeset: changeset)
end
end
Here, we’re emitting an event that includes the duration measurement–tracking the duration of the web request–along with the context of the web request, described by the conn
struct.
Step 3: Defining and Attaching The Telemetry Handler
We need to define a handler that implements a callback function that will be invoked when our event is executed.
The callback function will match the specific event we’re emitting using function arity pattern matching.
Let’s define a module, Quantum.Telemetry.Metrics
, that implements a function, handle_event/4
:
# lib/quantum/telemetry/metrics.ex
defmodule Quantum.Telemetry.Metrics do
require Logger
alias Quantum.Telemetry.StatsdReporter
def handle_event([:phoenix, :request], %{duration: dur}, metadata, _config) do
# do some stuff like log a message or report metrics to a service like StatsD
Logger.info("Received [:phoenix, :request] event. Request duration: #{dur}, Route: #{metadata.request_path}")
end
end
Step 4: Attaching the Event to the Handler
In order for this module’s handle_event/4
function to be called when our [:phoenix, :request]
event is executed, we need to “attach” the handler to the event.
We do that with the help of Telemetry’s attach/4
function.
The attach/4
function takes in four arguments:
- A unique “handler ID” that will be used to look up the handler for the event later
- The event name
- The handler callback function
- Any handler config (which we don’t need to take advantage of for the purposes of our example)
We’ll call this function in our application’s start/2
function:
# lib/quantum/application.ex
def start(_, _) do
:ok = :telemetry.attach(
# unique handler id
"quantum-telemetry-metrics",
[:phoenix, :request],
&Quantum.Telemetry.Metrics.handle_event/4,
nil
)
...
end
Now that we’ve defined and emitted our event, and attached a handler to that event, the following will occur:
- When a user visit the
/register
route and hits thenew
action of theUserController
- We’ll emit the Telemetry event, including the request duration and the
conn
like this::telemetry.execute([:phoenix, :request], %{duration: System.monotonic_time() - start}, conn)
- Then our
Quantum.Telemetry.Metrics.handle_event/4
function will be invoked, with the arguments of the event name, the measurement map including the request duration, and the measurement metadata, for which we passed in theconn
.
So, if we run the server with mix phx.server
, and visit http://localhost:4000/register/new
, we should see the following logged to our terminal:
[info] Received [:phoenix, :request] event. Request duration: 18000, Route: /register/new
This log statement is just one example of what we could do to respond to the Telemetry event. Later on, we’ll use the information in this event to report a metric to StatsD.
Next up, we’ll take a look under the hood of the Telemetry library to understand how emitting our event results in the invocation of our handler.
Telemetry Under The Hood
How does Telemetry invoke our handler callback function when an event is emitted? It leverages ETS! Telemetry stores our event and associated handler in an ETS table when we call :telemetry.attach/4
. When we call :telemetry.execute/3
, Telemetry looks up the handler function for the given event in the ETS table and executes it.
In the next sections, we’ll walk through some Telemetry source code so get a better understanding of how this process works. If you’re new to Erlang (like me!), no problem. Just do your best to read through the code for a high-level understanding.
Attaching Handlers to Events
The :telemetry.attach/4
function stores the handler and its associated events in an ETS table, under the unique handler ID we provide.
If we peek at the attach/4
source code, we can see the call to insert into ETS here
% telemetry/src/telemetry.erl
% inside the attach/4 function:
telemetry_handler_table:insert(HandlerId, EventNames, Function, Config).
Looking at the telemetry_handler_table
source code, we can see that the handler is stored in the ETS table like this:
% telemetry/src/telemetry_handler_table.erl
% inside the insert/5 function:
Objects = [#handler{id=HandlerId,
event_name=EventName,
function=Function,
config=Config} || EventName <- EventNames],
ets:insert(?MODULE, Objects)
So, each handler is stored in ETS with the format:
{
id=HandlerId,
event_name=EventName,
function=HandlerFunction,
config=Config
}
Where the HandlerId
EventName
, HandlerFunction
and Config
are set to whatever we passed into our call to :telemetry.attach/4
.
Executing Events
When we call :telemetry.execute/3
, Telemetry will look up the handler by the event name and invoke its callback function. Let’s take a look at the source code for :telemetry.execute/3
here:
% telemetry/src/telemetry.erl
-spec execute(EventName, Measurements, Metadata) -> ok when
EventName :: event_name(),
Measurements :: event_measurements() | event_value(),
Metadata :: event_metadata().
execute(EventName, Value, Metadata) when is_number(Value) ->
?LOG_WARNING("Using execute/3 with a single event value is deprecated. "
"Use a measurement map instead.", []),
execute(EventName, #{value => Value}, Metadata);
execute(EventName, Measurements, Metadata) when is_map(Measurements) and is_map(Metadata) ->
Handlers = telemetry_handler_table:list_for_event(EventName),
ApplyFun =
fun(#handler{id=HandlerId,
function=HandlerFunction,
config=Config}) ->
try
HandlerFunction(EventName, Measurements, Metadata, Config)
catch
?WITH_STACKTRACE(Class, Reason, Stacktrace)
detach(HandlerId),
?LOG_ERROR("Handler ~p has failed and has been detached. "
"Class=~p~nReason=~p~nStacktrace=~p~n",
[HandlerId, Class, Reason, Stacktrace])
end
end,
lists:foreach(ApplyFun, Handlers).
Let’s break down this process:
First, look up the handlers for the event in ETS:
% telemetry/src/telemetry.erl
Handlers = telemetry_handler_table:list_for_event(EventName)
Looking at the telemetry_handler_table.list_for_event/1
source code, we can see that the handler is looked up in ETS by the given event name like this:
% telemetry/src/telemetry_handler_table.erl
% inside list_for_event/1
ets:lookup(?MODULE, EventName)
This will return the list of stored handlers for the event, where each handler will know its handle ID, handle function and any config:
{
id=HandlerId,
function=HandlerFunction,
config=Config
}
Then, establish an ApplyFun
to be called for each handler
The ApplyFun
will invoke the given handler’s HandleFunction
with the event, measurements and metadata passed in via the call to :telemetry.execute/3
, along with any config that was stored in ETS.
% telemetry/src/telemetry.erl
ApplyFun =
fun(#handler{id=HandlerId,
function=HandlerFunction,
config=Config}) ->
try
HandlerFunction(EventName, Measurements, Metadata, Config)
catch
?WITH_STACKTRACE(Class, Reason, Stacktrace)
detach(HandlerId),
?LOG_ERROR("Handler ~p has failed and has been detached. "
"Class=~p~nReason=~p~nStacktrace=~p~n",
[HandlerId, Class, Reason, Stacktrace])
end
end
Lastly, iterate over the Handlers
and invoke the ApplyFun
for each handler
lists:foreach(ApplyFun, Handlers).
And that’s it!
Putting It All Together
To summarize, when we “attach” an event to a handler, we are storing the handler and its callback function in ETS under that event name. Later, when an event is “executed”, Telemetry looks up the handler for the event and executes the callback function. Pretty simple.
Now that we understand how our Telemetry pipeline works, we’re ready to consider the last piece of the puzzle: event reporting.
Reporting Events to StatsD
What you do with your event is up to you, but one common strategy is to report metrics to StatsD. In this example, we’ll use the Statix
library to report metrics describing our event to StatsD.
First, we’ll install Statix and run mix deps.get
# add the following to the `deps` function of your mix.exs file
{:statix, ">= 0.0.0"}
Next up, we define a module that uses Statix
:
# lib/quantum/telemetry/statsd_reporter.ex
defmodule Quantum.Telemetry.StatsdReporter do
use Statix
end
We need to start the StatsdReporter
in our application’s start/2
function:
# lib/quantum/application.ex
def start(_, _) do
:ok = Quantum.Telemetry.StatsdReporter.connect()
:ok = :telemetry.attach(
# unique handler id
"quantum-telemetry-metrics",
[:phoenix, :request],
&Quantum.Telemetry.Metrics.handle_event/4,
nil
)
...
end
Now we can call on our Quantum.Telemetry.StatsdReporter
in our event handler to emit metrics to StatsD:
# lib/quantum/telemetry/metrics.ex
defmodule Quantum.Telemetry.Metrics do
require Logger
alias Quantum.Telemetry.StatsdReporter
def handle_event([:phoenix, :request], %{duration: dur}, metadata, _config) do
StatsdReporter.increment("phoenix.request.success", 1)
StatsdReporter.timing("phoenix.request.success", dur)
end
end
Here, we’re reporting a counter metric that tracks the number of such request events, as well as a timing metric that tracks the duration of web requests.
Now, if we run our app and visit the /register
route a few times, we should see the following emitted to StatsD:
{
counters: {
'quantum.phoenix.request': 7
},
timers: {
'quantum.phoenix.request': [
18000, 18000,
19000, 19000,
20000, 22000,
24000
]
},
timer_data: {
'quantum.phoenix.request': {
count_90: 6,
mean_90: 19333.333333333332,
upper_90: 22000,
sum_90: 116000,
sum_squares_90:<PHONE_NUMBER>,
std: 2070.1966780270627,
upper: 24000,
lower: 18000,
count: 7,
count_ps: 0.7,
sum: 140000,
sum_squares:<PHONE_NUMBER>,
mean: 20000,
median: 19000
}
},
counter_rates: {
'quantum.phoenix.request': 0.7
}
}
NOTE: To install and run StatsD locally follow the simple guide here.
This reporting leaves something to be desired. We’re not currently taking advantage of the request context, passed into the handle_event/4
function as the metadata
argument. This metric alone is not very helpful from an observability standpoint since it doesn’t tell us anything about which endpoint received the request, who sent it and what the response was.
We have two options here. We can emit a more specific event from our controller, something like:
:telemetry.execute([:phoenix, :request, :register], %{duration: System.monotonic_time() - start}, conn)
This leaves us on the hook for defining and emitting custom events from every controller action. Soon it will be hard to keep track of and standardize all of these events.
We could instead add some tags to the metric we are sending to StatsD in the event handler:
StatsdReporter.increment("phoenix.request.success", 1, tags: [metadata.request_path])
StatsdReporter.timing("phoenix.request.success", dur, tags: [metadata.request_path])
The standard StatsD agent does not support tagging, and will error if we use tags here. However, if you are reporting to the DogStatsD agent with the goal of sending metrics to Datadog, your tags will be successfully applied like this:
quantum.phoenix.request:1|c|#/register/new
quantum.phoenix.request:21000|ms|#/register/new
We won’t dig into solving this problem now. Instead, we’re highlighting the fact that metrics reporting is complex. It’s a hard problem to solve and we could easily throw many hours and lots of code at it.
Conclusion
This seems hard. Is this too hard?
Telemetry provides a simple interface for instrumentation, but our barebones example leaves a lot to be desired. Earlier, we identified a need to instrument and report on all of the web requests received by our app. We want to be able to aggregate and analyze metrics describing the request times and counts across our web application, and we want the data we emit describing these data points to be information rich so that we can slice it by endpoint, response status and more. In this way, our app becomes observable, i.e. its outputs can tell use about its state.
In our current approach, however, we are manually emitting just one Telemetry event for one specific endpoint. This approach leaves us on the hook for manually emitting Telemetry events for every request, from every endpoint.
Our reporting mechanism, currently set up to send metrics to StatsD, is also a little problematic. Not only did we have to do the work to setup our own reporter, with the help of the Statix
library, we’re not properly taking advantage of tagging or our rich event context. We’ll have to do additional work to utilize our event context, either through tagging with a DogStatsD reporter (even more work to set up a whole new reporter!) or by updating the name of the event itself.
“Wait a minute”, you might be thinking, “I thought Telemetry was supposed to standardize instrumentation events and make it fast and easy to operate on and report those events. Why do I still have to emit all my own events and be on the hook for all of my reporting needs?”
Next Up
Well the answer is, you don’t have to emit all of your own events or be responsible for all of your reporting! Now that we understand how to set up a Telemetry pipeline, and how it works under the hood to store and execute callbacks for events using ETS, we’re ready to rely on some handy abstractions that additional Telemetry libraries provide.
Surprise! Phoenix and Ecto are already emitting common events from source code, including request counts and duration. The Telemetry.Metrics
library will make it super easy for us to hook into these events without defining and attaching our own handlers.
Further, Telemetry provides a number of reporting clients, including a StatsD reporter, that we can plug into our Telemetry.Metrics
module for free metrics reporting to StatsD or DogStatsD, allowing us to take advantage of event metadata with tagging.
In the next post, we’ll leverage Telemetry.Metrics
and the TelemetryStatsdReporter
to observe, format and report the Telemetry event we established here. In doing so, we’ll abstract away the need for our custom handler and our custom StatsD reporter.
See you soon!

These set of visualizations show changes in temperature and salinity with depth for the first ice-tethered profiler deployed, ITP 1. Pressure is closely correlated with depth and thus the terms are interchangeable in this context. Pressure is measured in decibars (dbar), temperature in degrees Celsius (°C), and salinity in practical salinity units (psu).
The visualization to the right demonstrates each profile through the seasons of the machine's journey. Winter is pictured as dark blue, followed by spring in green, summer in pink and fall in light blue. The tabs can be used to change the focus of the plot, either viewing all temperature profiles, all salinity profiles, or profiles by season. Notice how pressure changes on the y-axis. It may seem weird that the numbers become smaller further away from the origin. The top of the graph corresponds to the surface of the ocean, where there is no hydrostatic pressure.
Questions for thought:
What changes or patterns do you observe throughout the water column? Between seasons? What range of temperature do you observe? Salinity? How could you interpret the steep drop-off present on every salinity graph, beginning around 400 dbar?
Changes with Depth over Time
The second and third plots are heatmaps, which indicate temperature or salinity through the use of color over a period of time. We can see that the y-axis from the first set of graphs is the same and shows pressure or depth. c A day’s worth of temperature and salinity data is averaged for each interval of depth, so each day is a snapshot in time. Therefore, the heatmaps represent consecutive snapshots over the duration of an ITP machine’s active lifetime.
Questions for thought:
What changes or patterns do you observe over time? Can you match patterns to those observed in the earlier graph? If so, how do you interpret them? What can you infer from the consistency of patterns over time for temperature? For salinity?

The Mayor invites you
As Mayor of the great City of New Orleans, I invite you to visit our city to experience the excitement of Mardi Gras!
Mrs. LaToya Cantrell, Mayor of New Orleans
The Carnival season officially begins each year on Jan. 6 -- the Feast of the Epiphany, also called Twelfth Night or Kings’ Day.
Spectacular parades with colorful, creative floats start rolling before Mardi Gras Day. Our private Carnival clubs, called krewes, take on royalty status and throw beads, doubloons and toys to parade goers. Visitors quickly learn to say, "Throw me something mister!"
The culmination of Mardi Gras in New Orleans begins early on Mardi Gras Day when the Zulu Social Aid & Pleasure Club and the Rex Organization parade through the city. Music, food and elaborate costumes add to the fun-filled day of excitement for revelers of all ages.
New Orleans, with its unmatched culture and world-famous music and cuisine, is an exciting place to be at any time of the year. We invite everyone to experience Mardi Gras at least once in their lifetime. Make your plans now to be a part of this great tradition and see firsthand why we say, "Laissez les bon temps rouler!"
Sincerely,
LaToya Cantrell
Mayor of New Orleans
Mardi Gras in New Orleans
Mardi Gras in New Orleans
The holiday of Mardi Gras is celebrated in all of Louisiana, including the city of New Orleans. Celebrations are concentrated for about two weeks before and through Shrove Tuesday, the day before Ash Wednesday (the start of lent in the Western Christian tradition). Usually there is one major parade each day (weather permitting); many days have several large parades. The largest and most elaborate parades take place the last five days of the Mardi Gras season. In the final week, many events occur throughout New Orleans and surrounding communities, including parades and balls (some of them masquerade balls).
The parades in New Orleans are organized by social clubs known as krewes; most follow the same parade schedule and route each year. The earliest-established krewes were the Mistick Krewe of Comus, the earliest, Rex, the Knights of Momus and the Krewe of Proteus. Several modern "super krewes" are well known for holding large parades and events, such as the Krewe of Endymion (which is best known for naming celebrities as grand marshals for their parades), the Krewe of Bacchus (similarly known for naming celebrities as their Kings), as well as the Zulu Social Aid & Pleasure Club—a predominantly African American krewe. Float riders traditionally toss throws into the crowds. The most common throws are strings of colorful plastic beads, doubloons, decorated plastic "throw cups", Moon Pies, and small inexpensive toys, but throws can also include lingerie and more sordid items. Major krewes follow the same parade schedule and route each year.
The culmination of Mardi Gras in New Orleans begins early on Mardi Gras Day when the Zulu Social Aid & Pleasure Club and the Rex Organization parade through the city. Music, food and elaborate costumes add to the fun-filled day of excitement for revelers of all ages.
While many tourists center their Carnival season activities on Bourbon Street and in New Orleans and Dauphin, major parades originate in the Uptown and Mid-City districts and follow a route along St. Charles Avenue and Canal Street, on the upriver side of the French Quarter. Mardi Gras day traditionally concludes with the "Meeting of the Courts" between Rex and Comus.
