# how can I change this middleware to only call Raven.captureException when a message is placed in the retries queue, let's say, for the third time?

module Raven
  class Sidekiq
    def call(worker, msg, queue)
      begin
        yield
      rescue => ex
        Raven.captureException(ex)
        raise
      end
    end
  end
end

::Sidekiq.configure_server do |config|
  config.server_middleware do |chain|
    chain.add ::Raven::Sidekiq
  end
end

Currently, most of the bug-tracking middlewares are really set up to notify the exception tracker on every exception. because of the way sidekiq is made, sometimes sidekiq is a little eager, starts before the database is done, and then works on the first retry. Is there any way to code this middleware so that I notify the exception tracker on the "nth" retry?

Are you referring to the transactional issue where Sidekiq tries to find data that hasn't committed yet?

That issue is covered in the FAQ, use an after_commit callback.
