How to set the age out time for specific Spectrum alerts based on Alert type
Release : 10.3.x , 10.4.x
Component : Spectrum Alarm & Event Management
This can be achieved by using the "Alarm Age-Out Time" functionality located in the "Alarm Management" subview of the VNM model. Below is a more detailed description:
Alarm Age-Out Time (hours):
Defines how long an alarm can exist in CA Spectrum. Once an alarm has existed for the number of hours that you specify by this attribute, it is a candidate for automatic removal. To disable this functionality, set this attribute to zero (0).
Every hour, CA Spectrum checks the status of all alarms in the landscape and uses this option to determine whether alarms are cleared. Therefore, an alarm is not removed at the precise moment when its existence time has exceeded the time-out. An alarm can be, at most, an hour “overdue.”
You cannot age out non-user clearable alarms. The system functionality that generates such alarms, clears them. Maintenance Mode, Device Has Stopped Responding, and Management Agent Lost are the non-user clearable alarms.
If users would like to filter this functionality for certain alarms, you can achieve this by setting the following option located in the same subview:
"Age out Alarm Cause IDs Usage Age Out Only Alarms in Cause ID List"
Then you will need to add the Cause ID's to the table below it. This Cause ID can be found on the alarms tab under the "Cause Code" column or you can also find it for specific events/alarms within the Event Configuration Editor Tool.
