Errbit TravisCI Code Climate Coveralls Dependency Status

The open source, self-hosted error catcher

Errbit is a tool for collecting and managing errors from other applications. It is Airbrake (formerly known as Hoptoad) API compliant, so if you are already using Airbrake, you can just point the airbrake gem to your Errbit server.

Errbit may be a good fit for you if:

  • Your exceptions may contain sensitive data that you don’t want sitting on someone else’s server
  • Your application is behind a firewall
  • You’d like to brand your error catcher
  • You want to add customer features to your error catcher
  • You’re crazy and love managing servers

If this doesn’t sound like you, you should probably stick with a hosted service such as Airbrake.

The list of requirements to install Errbit are :

  • Ruby 1.9.3 or higher
  • MongoDB 2.2.0 or higher

Errbit uses Ruby 2.0.0 as a default. However, it is compatible with Ruby 1.9.3 and above.


Note: This app is intended for people with experience deploying and maintaining Rails applications. If you’re uncomfortable with any steps below then Errbit is not for you.

Set up your local box or server(Ubuntu):

  • Install MongoDB. Follow the directions here, then:
apt-get update
apt-get install mongodb-10gen
  • Install libxml, libzip, libssl and libcurl
apt-get install libxml2 libxml2-dev libxslt-dev libcurl4-openssl-dev libzip-dev libssl-dev
  • Install Bundler
gem install bundler

Running Locally:

  • Install dependencies
bundle install
  • Bootstrap Errbit. This will copy over config.yml and also seed the database.
rake errbit:bootstrap
  • Update the config.yml and mongoid.yml files with information about your environment

  • Start Server

script/rails server


  • Copy config/deploy.example.rb to config/deploy.rb
  • Update the deploy.rb or config.yml file with information about your server
  • Setup server and deploy
cap deploy:setup deploy db:create_mongoid_indexes

(Note: The capistrano deploy script will automatically generate a unique secret token.)

Deploying to Heroku:

  • Clone the repository
git clone
  • Update db/seeds.rb with admin credentials for your initial login.

  • Run bundle

  • Create & configure for Heroku

gem install heroku
heroku create example-errbit
# If you really want, you can define your stack and your buildpack. the default is good to us :
# heroku create example-errbit --stack cedar --buildpack
heroku addons:add mongolab:sandbox
heroku addons:add sendgrid:starter
heroku config:add HEROKU=true
heroku config:add SECRET_TOKEN="$(bundle exec rake secret)"
heroku config:add
heroku config:add
git push heroku master
  • Seed the DB (NOTE: No bootstrap task is used on Heroku!) and create index
heroku run rake db:seed
heroku run rake db:mongoid:create_indexes
  • If you are using a free database on Heroku, you may want to periodically clear resolved errors to free up space.

    • With the heroku-scheduler add-on (replacement for cron):
    # Install the heroku scheduler add-on
    heroku addons:add scheduler:standard
    # Go open the dashboard to schedule the job.  You should use
    # 'rake errbit:db:clear_resolved' as the task command, and schedule it
    # at whatever frequency you like (once/day should work great).
    heroku addons:open scheduler
    • With the cron add-on:
    # Install the heroku cron addon, to clear resolved errors daily:
    heroku addons:add cron:daily
    • Or clear resolved errors manually:
    heroku run rake errbit:db:clear_resolved
  • You may want to enable the deployment hook for heroku :

heroku addons:add deployhooks:http --url="http://YOUR_ERRBIT_HOST/deploys.txt?api_key=YOUR_API_KEY"
  • You may also want to configure a different secret token for each deploy:
heroku config:add SECRET_TOKEN=some-secret-token
  • Enjoy!


Configuring GitHub authentication:

  • In config/config.yml, set github_authentication to true
  • Register your instance of Errbit at:

If you hosted Errbit at, you would fill in:

Callback URL:
  • After you have registered your app, set github_client_id and github_secret in config/config.yml with your app’s Client ID and Secret key.

After you have followed these instructions, you will be able to Sign in with GitHub on the Login page.

You will also be able to link your GitHub profile to your user account on your Edit profile page.

If you have signed in with GitHub, or linked your GitHub profile, and the App has a GitHub repo configured, then you will be able to create issues on GitHub. You will still be able to create an issue on the App’s configured issue tracker.

You can change the requested account permissions by setting github_access_scope to:

['repo'] Allow creating issues for public and private repos.
['public_repo'] Only allow creating issues for public repos.
[] No permission to create issues on any repos.

GitHub authentication when served on Heroku

You will need to set up Heroku variables accordingly as described in Configuring GitHub authentication:

heroku config:add GITHUB_AUTHENTICATION=true
heroku config:add GITHUB_CLIENT_ID=the_client_id_provided_by_GitHub
heroku config:add GITHUB_SECRET=the_secret_provided_by_GitHub
  • GITHUB_ACCESS_SCOPE - set only one scope repo or public_repo. If you really need to put more than one, separate them with comma.
heroku config:add GITHUB_ACCESS_SCOPE=repo,public_repo
  • GITHUB_ORG_ID [optional] - If set, any user of the specified GitHub Organization can login. If it is their first time, an account will automatically be created for them.
heroku config:add GITHUB_ORG_ID=1234567

Note: To avoid restarting your Heroku app 4 times you can set Heroku variables in a single command, i.e:

heroku config:add GITHUB_AUTHENTICATION=true \
GITHUB_CLIENT_ID=the_client_id_provided_by_GitHub \
GITHUB_SECRET=the_secret_provided_by_GitHub \

Configuring LDAP authentication:

  • In config/config.yml, set user_has_username to true
  • Follow the instructions at to set up the devise_ldap_authenticatable gem.
  • Ensure to set config.ldap_create_user = true in config/initializers/devise.rb, this enables creating the users from LDAP, otherwhise login will not work.
  • Create a new initializer (e.g. config/initializers/devise_ldap.rb) and add the following code to enable ldap authentication in the User-model:
    Errbit::Config.devise_modules << :ldap_authenticatable
  • If you are authenticating by username, you will need to set the user’s email manually before authentication. You must add the following lines to app/models/user.rb:
  def ldap_before_save
    name = Devise::LDAP::Adapter.get_ldap_param(self.username, "givenName")
    surname = Devise::LDAP::Adapter.get_ldap_param(self.username, "sn")
    mail = Devise::LDAP::Adapter.get_ldap_param(self.username, "mail") = (name + surname).join ' ' = mail.first
  • Now login with your user from LDAP, this will create a user in the database
  • Open a rails console and set the admin flag for your user:
user = User.first
user.admin = true!


When upgrading Errbit, please run:

git pull origin master # assuming origin is the repo
bundle install
rake db:migrate
rake assets:precompile

This will ensure that your application stays up to date with any schema changes.

Upgrading errbit from version 0.2 to 0.3

The MongoDB connection file config/mongoid.yml has changed between version 0.2 and 0.3. We have provided a new example configuration file to use at config/mongoid.example.yml.

This change is not needed if you use ENV variables to define access to your MongoDB database.

User information in error reports

Errbit can now display information about the user who experienced an error. This gives you the ability to ask the user for more information, and let them know when you’ve fixed the bug.

If you are running a Rails application and would like to include information about the current user in your error reports, you can replace the airbrake gem in your Gemfile with airbrake_user_attributes. This gem is a wrapper around the airbrake gem and will automatically inject information about the user into any error reports, so long as your controllers respond to a #current_user method. The user’s attributes are filtered to remove authentication fields.

If user information is received with an error report, it will be displayed under the User Details tab:

User details tab

(This tab will be hidden if no user information is available.)

Javascript error notifications

You can log javascript errors that occur in your application by including the following script tag before any javascript is loaded in your application.

<script src="//YOUR-ERRBIT-HOST/javascripts/notifier.js" type="text/javascript"></script>

Using custom fingerprinting methods

Errbit allows you to use your own Fingerprinting Strategy. If you are upgrading from a very old version of errbit, you can use the LegacyFingerprint for compatibility. The fingerprint strategy can be changed by adding an initializer to errbit:

# config/fingerprint.rb
ErrorReport.fingerprint_strategy = LegacyFingerprint

The easiest way to add custom fingerprint methods is to simply subclass Fingerprint

What if Errbit has an error?

Errbit will log it’s own errors to an internal app named Self.Errbit. The Self.Errbit app will be automatically created whenever the first error happens.

If your Errbit instance has logged an error, we would appreciate a bug report on GitHub Issues. You can post this manually at, or you can set up the GitHub Issues tracker for your Self.Errbit app:

  • Go to the Self.Errbit app’s edit page. If that app does not exist yet, go to the apps page and click Add a new App to create it. (You can also create it by running rake airbrake:test.)

  • In the Issue Tracker section, click GitHub Issues.

  • Fill in the Account/Repository field with errbit/errbit.

  • Fill in the Username field with your github username.

  • If you are logged in on GitHub, you can find your API Token on this page:

  • Save the settings by clicking Update App (or Add App)

  • You can now easily post bug reports to GitHub Issues by clicking the Create Issue button on a Self.Errbit error.

Use Errbit with applications written in other languages

In theory, any Airbrake-compatible error catcher for other languages should work with Errbit. Solutions known to work are listed below:

PHP (>= 5.3) [flippa/errbit-php](
OOP PHP (>= 5.3) [emgiezet/errbitPHP](
Python [mkorenkov/]( , [pulseenergy/airbrakepy](

Contributing to Errbit

We welcome any contributions. If you need to tweak Errbit for your organization’s needs, there are probably other users who will appreciate your work. Please try to determine whether or not your feature should be global or optional, and make optional features configurable via config/config.yml.

Examples of optional features:

  • Enable / disable user comments on errors.
  • Adding a username field to the User model.

How to contribute:

  • Fork the project.
  • Make your feature addition or bug fix.
