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.

Note: This app is intended for people with experience deploying and maintining Rails applications. If you’re uncomfortable with any step 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 and libcurl
apt-get install libxml2 libxml2-dev libxslt-dev libcurl4-openssl-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

(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.

  • Create & configure for Heroku

gem install heroku
heroku create example-errbit --stack cedar
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!)
heroku run rake db:seed
  • 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

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:
  before_save :set_ldap_email
  def set_ldap_email = Devise::LdapAdapter.get_ldap_param(self.username, "mail")
  • 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

If we change the way that data is stored, this will run any migrations to bring your database up to date.

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 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, which wraps the airbrake gem and injects user information. It will inject information about the current user into the error report if your Rails app’s controller responds 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.)

Adding javascript errors notifications

Errbit easily supports javascript errors notifications. You just need to add config.js_notifier = true to the errbit initializer in the rails app.

Errbit.configure do |config|    = 'YOUR-ERRBIT-HOST'
  config.api_key = 'YOUR-PROJECT-API-KEY'
  config.js_notifier = true

Then get the notifier.js from errbit/public/javascript/notifier.js and add to application.js on your rails app or inlcude http://YOUR-ERRBIT-HOST/javascripts/notifier.js on your application.html.erb.

  • Project id is the identifier of your project, i.e. awesomeapp for project at
  • Card properties are comma separated key value pairs. You must specify a ‘card_type’, but anything else is optional, e.g.:
card_type = Defect, status = Open, priority = Essential

GitHub Issues Integration

  • For ‘Account/Repository’, the account will either be a username or organization. i.e. errbit/errbit
  • You will also need to provide your username and password for your GitHub account.
    • (We’d really appreciate it if you wanted to help us implement OAuth instead!)

Bitbucket Issues Integration

  • For ‘BITBUCKET REPO’ field, the account will either be a username or organization. i.e. errbit/errbit
  • You will also need to provide your username and password for your Bitbucket account.

Gitlab Issues Integration

  • Account is the host of your gitlab installation. i.e.
  • To authenticate, Errbit uses token-based authentication. Get your API Key in your user settings (or create special user for this purpose)
  • You also need to provide project ID (it needs to be Number) for issues to be created

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.
