Module: Rack::Timeout::Rollbar

Defined in:
lib/rack/timeout/rollbar.rb

Overview

Groups timeout exceptions in rollbar by exception class, http method, and url.

Usage: after requiring rollbar (say, in your rollbar initializer file), call:

require "rack/timeout/rollbar"

Ruby 2.1 is required as we use ‘Module.prepend`.

To use a custom fingerprint for grouping:

Rack::Timeout::Rollbar.fingerprint do |exception, env|
  # … return some kind of string derived from exception and env
end
