Added

• Add support for heartbeat check-ins.

  Use the Appsignal::CheckIn.heartbeat method to send a single heartbeat check-in event from your application. This can be used, for example, in your application's main loop:

  Ruby

  loop do
    Appsignal::CheckIn.heartbeat("job_processor")
    process_job
  end

  Heartbeats are deduplicated and sent asynchronously, without blocking the current thread. Regardless of how often the .heartbeat method is called, at most one heartbeat with the same identifier will be sent every ten seconds.

  Pass continuous: true as the second argument to send heartbeats continuously during the entire lifetime of the current process. This can be used, for example, after your application has finished its boot process:

  Ruby

  def main
    start_app
    Appsignal::CheckIn.heartbeat("my_app", continuous: true)
  end

• Include the first backtrace line from error causes to show where each cause originated in the interface.
