Why Are Acknowledged By and Cleared By Displayed as <System operator> for an Alarm?
Question
Why are Acknowledged By and Cleared By displayed as <System operator> for an alarm?
Answer
After a processing rule of full current alarm cache is executed, some current alarms are moved to the historical alarm list. For these alarms, Acknowledged By and Cleared By are displayed as <System operator>.
After some current alarms are acknowledged based on the auto acknowledgement rules, Acknowledged By of these alarms is displayed as <System operator>.
For details about the mechanisms of processing rules of the full current alarm cache and auto acknowledgement rules, see Table 6-10.

Description |
|---|---|
Processing rule of the full current alarm cache |
To prevent excessive current alarms from deteriorating system performance, alarm management provides a full-alarm processing rule. When the number of current alarms in the database reaches the upper threshold, alarm management applies the following two rules to move some alarms to the historical alarm list until the number of alarms falls to 90% of the upper threshold.

Auto acknowledgement rule |
The system automatically acknowledges unacknowledged and cleared alarms that meet the conditions based on the auto acknowledgment rules. |
