About Purging Alarms

Purge or delete alarms only if you need to maintain the alarm data efficiently. You may purge alarms if they become outdated or redundant, or due to limited disk space. Purging alarms gives you the flexibility and control of deleting alarms for a specified time range or using a specific alarm ID. Purge alarms using a time range when an entire time period of alarms is no longer of interest. Purge alarms by ID when you need to preserve certain alarms in a time range and remove the others.

The purged alarms are not lost but are moved to a backup file that can be restored on the current system or another system, if needed. Also, an audit trail entry is made indicating the user and time range purged. An audit trail ensures that the alarm data was not purged unintentionally, and is recorded for any auditing purpose for future use.

To purge alarms, you need to be a member of the ihSecurityAdmins security group. To protect against accidental purge, make sure that only certain people are members of this group.

You can purge alarms from the Administrator or through a command line program. For more information, refer to Using ihPurgeAlarms.exe to Purge Alarms from the Command Line section.
