Errbit | Closer to Code

If you've set up Errbit/Airbrake and you use Sidekiq, by default you would expect, that Errbit tracks things that happen in Sidekiq workers as well. Unfortunately it doesn't.

In order to make Sidekiq retry failed jobs in needs to catch and handle exceptions on its own. And that's the reason why you need a bit of "magic" to make it work with Errbit. You need to add an custom error handler that will notify Errbit app about errors that occured in Sidekiq workers.

To do so, just create an initializer like this:

# Errbit error catching for Sidekiq workers
Sidekiq.configure_server do |config|
  config.error_handlers << Proc.new { |ex,ctx_hash| Airbrake.notify_or_ignore(ex, ctx_hash) }
end

And that's all!

Warning: This post is outdated and this fix will work only with old Airbrake version (v4) - it does not work with the v4 version of Airbrake notifier. If you're looking for a solution for Airbrake v5, please refere to this post: Errbit + HTTPS: Setting up Errbit reporter (Airbrake v5 gem) to work with self-signed HTTPS certificate

Having an error catcher like Errbit behind SSL is generally a good idea. Especially when Errbit is hosted on a different server than you application (for example when you manage multiple apps with one Errbit instance). In many cases you will have a self-signed certificate (why would you pay for a cert for internal tool). If you try to use it with Airbrake, you will see following error:

2.1.0 :002 &gt; Airbrake.notify Exception.new('test')

In order to make it work you need to disable SSL verification for Ruby:

OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE

Of course keep in mind, that it will disable SSL verification for all other libs as well.

Whole Errbit config should look like this:

Airbrake.configure do |config|
  config.api_key = 'api_key'
  config.host    = 'errbit.domain'
  config.port    = 443
  config.secure  = true
  config.ignore_only = ['ActiveRecord::RecordNotFound']
end if Rails.env.production?

OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE
