Airbrake is an online tool that provides robust exception tracking in any of your Ruby applications. In doing so, it allows you to easily review errors, tie an error to an individual piece of code, and trace the cause back to recent changes. The Airbrake dashboard provides easy categorization, searching, and prioritization of exceptions so that when errors occur, your team can quickly determine the root cause.
This library is built on top of Airbrake Ruby. The difference
between Airbrake and Airbrake Ruby is that the airbrake gem is just a
collection of integrations with frameworks or other libraries. The
airbrake-ruby gem is the core library that performs exception sending and
other heavy lifting.
Normally, you just need to depend on this gem, select the integration you are
interested in and follow the instructions for it. If you develop a pure
frameworkless Ruby application or embed Ruby and don't need any of the listed
integrations, you can depend on the airbrake-ruby gem and ignore this gem
entirely.
The list of integrations that are available in this gem includes:
- Heroku support (as an add-on)
- Web frameworks
- Job processing libraries
- Other libraries
- Plain Ruby scripts
Deployment tracking:
- Using Capistrano
- Using the Rake task
Add the Airbrake gem to your Gemfile:
gem 'airbrake'Invoke the following command from your terminal:
gem install airbrakeTo integrate Airbrake with your Rails application, you need to know your
project id and project key. Set AIRBRAKE_PROJECT_ID &
AIRBRAKE_PROJECT_KEY environment variables with your project's values and
generate the Airbrake config:
export AIRBRAKE_PROJECT_ID=<PROJECT ID>
export AIRBRAKE_PROJECT_KEY=<PROJECT KEY>
rails g airbrakeHeroku add-on users can omit specifying the key and the id. Heroku add-on's environment variables will be used (Heroku add-on docs):
rails g airbrakeThis command will generate the Airbrake configuration file under
config/initializers/airbrake.rb. Make sure that this file is checked into your
version control system. This is enough to start Airbraking.
In order to configure the library according to your needs, open up the file and edit it. The full list of supported configuration options is available online.
To test the integration, invoke a special Rake task that we provide:
rake airbrake:testIn case of success, a test exception should appear in your dashboard.
The Airbrake gem defines two helper methods available inside Rails controllers:
#notify_airbrake and #notify_airbrake_sync. If you want to notify Airbrake
from your controllers manually, it's usually a good idea to prefer them over
Airbrake.notify, because they automatically add
information from the Rack environment to notices. #notify_airbrake is
asynchronous, while #notify_airbrake_sync is synchronous (waits for responses
from the server and returns them). The list of accepted arguments is identical
to Airbrake.notify.
The library sends all uncaught exceptions automatically, attaching the maximum possible amount information that can help you to debug errors. The Airbrake gem is capable of reporting information about the currently logged in user (id, email, username, etc.), if you use an authentication library such as Devise. The library also provides a special API for manual error reporting. The description of the API is available online.
Additionally, the Rails integration offers automatic exception reporting in any Rake tasks[link] and Rails runner.
If you want to reuse Rails.application.config.filter_parameters in Airbrake
you can configure your notifier the following way:
# config/initializers/airbrake.rb
Airbrake.configure do |c|
c.blocklist_keys = Rails.application.config.filter_parameters
endThere are a few important details:
- You must load
filter_parameter_logging.rbbefore the Airbrake config - If you use Lambdas to configure
filter_parameters, you need to convert them to Procs. Otherwise you will getArgumentError - If you use Procs to configure
filter_parameters, the procs must return an Array of keys compatible with the Airbrake allowlist/blocklist option (String, Symbol, Regexp)
Consult the
example application, which
was created to show how to configure filter_parameters.
The dot notation introduced in rails/pull/13897 for
filter_parameters (e.g. a key like credit_card.code) is unsupported for
performance reasons. Instead, simply specify the code key. If you have a
strong opinion on this, leave a comment in
the dedicated issue.
In new Rails apps, by default, all the Airbrake logs are written into
log/airbrake.log. In older versions we used to write to wherever
Rails.logger writes. If you wish to upgrade your app to the new behaviour,
please configure your logger the following way:
c.logger = Airbrake::Rails.loggerTo use Airbrake with Sinatra, simply require the gem, configure it
and use our Rack middleware.
# myapp.rb
require 'sinatra/base'
require 'airbrake'
Airbrake.configure do |c|
c.project_id = 113743
c.project_key = 'fd04e13d806a90f96614ad8e529b2822'
# Display debug output.
c.logger.level = Logger::DEBUG
end
class MyApp < Sinatra::Base
use Airbrake::Rack::Middleware
get('/') { 1/0 }
end
run MyApp.run!To run the app, add a file called config.ru to the same directory and invoke
rackup from your console.
# config.ru
require_relative 'myapp'That's all! Now you can send a test request to localhost:9292 and check your
project's dashboard for a new error.
curl localhost:9292To send exceptions to Airbrake from any Rack application, simply use our Rack
middleware, and configure the notifier.
require 'airbrake'
require 'airbrake/rack'
Airbrake.configure do |c|
c.project_id = 113743
c.project_key = 'fd04e13d806a90f96614ad8e529b2822'
end
use Airbrake::Rack::MiddlewareNote: be aware that by default the library doesn't filter any parameters, including user passwords. To filter out passwords add a filter.
If you want to append additional information from web requests (such as HTTP headers), define a special filter such as:
Airbrake.add_filter do |notice|
next unless (request = notice.stash[:rack_request])
notice[:params][:remoteIp] = request.env['REMOTE_IP']
endThe notice object carries a real Rack::Request object in
its stash.
Rack requests will always be accessible through the :rack_request stash key.
The library comes with optional predefined builders listed below.
RequestBodyFilter appends Rack request body to the notice. It accepts a
length argument, which tells the filter how many bytes to read from the body.
By default, up to 4096 bytes is read:
Airbrake.add_filter(Airbrake::Rack::RequestBodyFilter.new)You can redefine how many bytes to read by passing an Integer argument to the filter. For example, read up to 512 bytes:
Airbrake.add_filter(Airbrake::Rack::RequestBodyFilter.new(512))For every route in your app Airbrake collects performance breakdown statistics. If you need to monitor a specific operation, you can capture your own breakdown:
def index
Airbrake::Rack.capture_timing('operation name') do
call_operation(...)
end
call_other_operation
endThat will benchmark call_operation and send performance information to
Airbrake, to the corresponding route (under the 'operation name' label).
Alternatively, you can measure performance of a specific method:
class UsersController
extend Airbrake::Rack::Instrumentable
def index
call_operation(...)
end
airbrake_capture_timing :index
endSimilarly to the previous example, performance information of the index method
will be sent to Airbrake.
We support Sidekiq v2+. The configurations steps for them are identical. Simply
require our integration and you're done:
require 'airbrake/sidekiq'If you required Sidekiq before Airbrake, then you don't even have to require
anything manually and it should just work out-of-box.
By default, Airbrake notifies of all errors, including reoccurring errors during
a retry attempt. To filter out these errors and only get notified when Sidekiq
has exhausted its retries you can add the RetryableJobsFilter:
Airbrake.add_filter(Airbrake::Sidekiq::RetryableJobsFilter.new)The filter accepts an optional max_retries parameter. When set, it configures
the amount of allowed job retries that won't trigger an Airbrake notification.
Normally, this parameter is configured by the job itself but this setting takes
the highest precedence and forces the value upon all jobs, so be careful when
you use it. By default, it's not set.
Airbrake.add_filter(
Airbrake::Sidekiq::RetryableJobsFilter.new(max_retries: 10)
)No additional configuration is needed. Simply ensure that you have configured your Airbrake notifier with your queue adapter.
Simply require the Resque integration:
require 'airbrake/resque'If you're working with Resque in the context of a Rails application, create a
new initializer in config/initializers/resque.rb with the following content:
# config/initializers/resque.rb
require 'airbrake/resque'
Resque::Failure.backend = Resque::Failure::AirbrakeNow you're all set.
Any Ruby app using Resque can be integrated with Airbrake. If you can require
the Airbrake gem after Resque, then there's no need to require
airbrake/resque anymore:
require 'resque'
require 'airbrake'
Resque::Failure.backend = Resque::Failure::AirbrakeIf you're unsure, just configure it similar to the Rails approach. If you use multiple backends, then continue reading the needed configuration steps in the Resque wiki (it's fairly straightforward).
Simply require our integration and you're done:
require 'airbrake/delayed_job'If you required DelayedJob before Airbrake, then you don't even have to require
anything manually and it should just work out-of-box.
Simply require our integration and you're done:
require 'airbrake/shoryuken'If you required Shoryuken before Airbrake, then you don't even have to require
anything manually and it should just work out-of-box.
Simply require our integration and you're done:
require 'airbrake/sneakers'If you required Sneakers before Airbrake, then you don't even have to require
anything manually and it should just work out-of-box.
The ActionCable integration sends errors occurring in ActionCable actions and subscribed/unsubscribed events. If you use Rails with ActionCable, there's nothing to do, it's already loaded. If you use ActionCable outside Rails, simply require it:
require 'airbrake/rails/action_cable'Airbrake offers Rake tasks integration, which is used by our Rails
integration[link]. To integrate Airbrake in any project,
just require the gem in your Rakefile, if it hasn't been required and
configure the notifier.
# Rakefile
require 'airbrake'
Airbrake.configure do |c|
c.project_id = 113743
c.project_key = 'fd04e13d806a90f96614ad8e529b2822'
end
task :foo do
1/0
endIf you want to convert your log messages to Airbrake errors, you can use our
integration with Ruby's Logger class from stdlib. All you need to do is to
wrap your logger in Airbrake's decorator class:
require 'airbrake/logger'
# Create a normal logger
logger = Logger.new($stdout)
# Wrap it
logger = Airbrake::AirbrakeLogger.new(logger)Now you can use the logger object exactly the same way you use it. For
example, calling fatal on it will both log your message and send it to the
Airbrake dashboard:
logger.fatal('oops')
The Logger class will attempt to utilize the default Airbrake notifier to
deliver messages. It's possible to redefine it via #airbrake_notifier:
# Assign your own notifier.
logger.airbrake_notifier = Airbrake::NoticeNotifier.newIn order to reduce the noise from the Logger integration it's possible to configure Airbrake severity level. For example, if you want to send only fatal messages from Logger, then configure it as follows:
# Send only fatal messages to Airbrake, ignore anything below this level.
logger.airbrake_level = Logger::FATALBy default, airbrake_level is set to Logger::WARN, which means it
sends warnings, errors and fatal error messages to Airbrake.
In order to configure a production logger with Airbrake integration, simply
overwrite Rails.logger with a wrapped logger in an after_initialize
callback:
# config/environments/production.rb
config.after_initialize do
# Standard logger with Airbrake integration:
# https://github.com/airbrake/airbrake#logger
Rails.logger = Airbrake::AirbrakeLogger.new(Rails.logger)
endBy default, the library collects Rails SQL performance stats. For standard Rails apps no extra configuration is needed. However if your app uses Rails engines, you need to take an additional step to make sure that the file and line information is present for queries being executed in the engine code.
Specifically, you need to make sure that your
Rails.backtrace_cleaner
has a silencer that doesn't silence engine code (will be silenced by
default). For example, if your engine is called blorgh and its main directory
is in the root of your project, you need to extend the default silencer provided
with Rails and add the path to your engine:
# config/initializers/backtrace_silencers.rb
# Delete default silencer(s).
Rails.backtrace_cleaner.remove_silencers!
# Define custom silencer, which adds support for the "blorgh" engine
Rails.backtrace_cleaner.add_silencer do |line|
app_dirs_pattern = %r{\A/?(app|config|lib|test|blorgh|\(\w*\))}
!app_dirs_pattern.match?(line)
endAirbrake supports any type of Ruby applications including plain Ruby scripts. If you want to integrate your script with Airbrake, you don't have to use this gem. The Airbrake Ruby gem provides all the needed tooling.
By notifying Airbrake of your application deployments, all errors are resolved when a deploy occurs, so that you'll be notified again about any errors that reoccur after a deployment. Additionally, it's possible to review the errors in Airbrake that occurred before and after a deploy.
There are several ways to integrate deployment tracking with your application, that are described below.
The library supports Capistrano v2 and Capistrano v3. In order to configure
deploy tracking with Capistrano simply require our integration from your
Capfile:
# Capfile
require 'airbrake/capistrano'If you use Capistrano 3, define the after :finished hook, which executes the
deploy notification task (Capistrano 2 doesn't require this step).
# config/deploy.rb
namespace :deploy do
after :finished, 'airbrake:deploy'
endIf you version your application, you can set the :app_version variable in
config/deploy.rb, so that information will be attached to your deploy.
# config/deploy.rb
set :app_version, '1.2.3'A Rake task can accept several arguments shown in the table below:
| Key | Required | Default | Example |
|---|---|---|---|
| ENVIRONMENT | No | Rails.env | production |
| USERNAME | No | nil | john |
| REPOSITORY | No | nil | https://github.com/airbrake/airbrake |
| REVISION | No | nil | 38748467ea579e7ae64f7815452307c9d05e05c5 |
| VERSION | No | nil | v2.0 |
Simply invoke rake airbrake:deploy and pass needed arguments:
rake airbrake:deploy USERNAME=john ENVIRONMENT=production REVISION=38748467 REPOSITORY=https://github.com/airbrake/airbrakeMake sure to require the library Rake integration in your Rakefile.
# Rakefile
require 'airbrake/rake/tasks'Then, invoke it like shown in the example for Rails.
- CRuby >= 2.6.0
- JRuby >= 9k
