Ruby agent v8.16.0

v8.16.0

Version 8.16.0 introduces more Ruby on Rails instrumentation (especially for Rails 6 and 7) for various Action*/Active* libraries whose actions produce Active Support notifications events.

• Add Various Ruby on Rails Library Instrumentations

  New instrumentation is now automatically provided by several Action*/Active* libaries that generate Active Support notifications. With each Ruby on Rails release, new the Rails libraries add new events and sometimes existing events have their payload parameters updated as well. The New Relic Ruby agent will now automatically process more of these events and parameters with New Relic segments created for each event. At a minimum, each segment gives timing information for the event. In several cases, all non-sensitive event payload parameters are also passed along in the segment.

  The agent now newly supports or has updated support for the following libraries:

  • Action Cable (for WebSockets) PR#1749
  • Action Controller (for the 'C' in MVC) PR#1744
  • Action Mailbox (for sending mail) PR#1740
  • Action Mailer (for routing mail) PR#1740
  • Active Job (for background jobs) PR#1742
  • Active Support (for caching operations) PR#1742

  The instrumentations for each of these libaries are all enabled by default, but can be independently disabled via configuration by using the following parameters:

  Configuration name	Default	Behavior
  disable_action_cable	false	If true, disables Action Cable instrumentation.
  disable_action_controller	false	If true, disables Action Controller instrumentation.
  disable_action_mailbox	false	If true, disables Action Mailbox instrumentation.
  disable_action_mailer	false	If true, disables Action Mailer instrumentation.
  disable_activejob	false	If true, disables Active Job instrumentation.
  disable_active_support	false	If true, disables Active Support instrumentation.
