Active and Inactive Rules

The Policies interface indicates whether a policy is active or inactive. Active rules show the slider to the right and filled. Inactive rules show the slider to the left and unfilled.

Active and Inactive status for a policy can be changed by toggling the slider position.

Tags

For each policy, a set of tags defines:

  • Which server or service the rule applies to

  • Whether the policy will generate a Warning or a Critical alert

Tags are specified when creating a custom policy, or when editing an existing policy.

Notifications

Alert events are shown in the Alerts interface.

Alert events will trigger a service alert notification, which can optionally be sent by email using Notification Channels.

For a policy to generate an email notification, the rule must be configured with the "Receive email notification" checkbox checked. This checkbox can be checked when creating a custom policy, or when editing an existing policy.

Conditions

Policies contain conditions which trigger the alert:

  • A metric or status condition is specified

  • For metrics, the metric value is compared against a threshold

  • An alert can be sent immediately or if the condition is sustained for a specific period of time
