Defined in:
lib/logstash/two/outputs/rollbar.rb

The Rollbar output will send events to the Rollbar event monitoring service. The only required field is a Rollbar project access token with post_server_item permissions. If you’re already using Rollbar to report errors directly from your applications, you can use the same token.
