Bases: object

Properties for creating a Composite Alarm.

Parameters:

  • alarm_rule (IAlarmRule) – Expression that specifies which other alarms are to be evaluated to determine this composite alarm’s state.

  • actions_enabled (Optional[bool]) – Whether the actions for this alarm are enabled. Default: true

  • actions_suppressor (Optional[IAlarm]) – Actions will be suppressed if the suppressor alarm is in the ALARM state. Default: - alarm will not be suppressed.

  • actions_suppressor_extension_period (Optional[Duration]) – The maximum duration that the composite alarm waits after suppressor alarm goes out of the ALARM state. After this time, the composite alarm performs its actions. Default: - 1 minute extension period will be set.

  • actions_suppressor_wait_period (Optional[Duration]) – The maximum duration that the composite alarm waits for the suppressor alarm to go into the ALARM state. After this time, the composite alarm performs its actions. Default: - 1 minute wait period will be set.

  • alarm_description (Optional[str]) – Description for the alarm. Default: - No description.

  • composite_alarm_name (Optional[str]) – Name of the alarm. Default: - Automatically generated name.
