Group escalations
Also known as message storm suppression
Overview
If many alarms are triggered within a short period of time, this can lead to a flood of notifications. To avoid this, alarms can be combined within an escalation. In this process, several incoming alarms are consolidated into a single escalation message, depending on individually defined conditions. In addition, certain alarm tags can be excluded from the combination, so that these continue to be escalated individually.
Procedure
Click on Engineering[A]
Click on escalation[B]
▷ The overview of the escalation configurations opens.
Click on [D]
▷ The window opens Combining alarms[D1].
Activate the switch [D2], to activate the combining of alarms.
Enter under [D3] the period in seconds within which the alarms must occur in order to be combined.
Enter under [D4] the minimum number of alarms that must occur within the defined period for them to be combined.
Select under [D5] the alarm tags that should be excluded from the combination (e.g. High Prio).
Click on Save[D6], to apply the changes.
Example
Conditions:
Period: 10 seconds
Minimum number: 5 alarms
Scenario 1:
Within 8 seconds, 5 alarms are triggered without excluded tags → The alarms are combined and sent as a single escalation message.
Scenario 2:
Within 10 seconds, 4 alarms are triggered → No combination, 4 separate escalation messages are sent.
Scenario 3:
Within 10 seconds, 7 alarms are triggered, 2 of them with the tag High Prio (excluded) → The 5 remaining alarms are combined, the 2 High Prio-alarms are escalated individually.
