Constructor Details

#initialize(interval: 300, message: "Some queues have a high latency", level: :warn) ⇒ Sentry

Returns a new instance of Sentry.

Parameters:

  • interval (Integer) (defaults to: 300) —

    How many seconds between Sentry alerts? This is similar to alert_interval on the Autoscaler, but Sentry has its own interval, since it is used for reporting, and not latency reduction.

  • message (String) (defaults to: "Some queues have a high latency") —

    Message to capture.

  • level (:debug, :info, :warning, :warn, :error, :fatal) (defaults to: :warn) —

    Sentry level.
