Setting the Current Alarm Threshold Warning

Prerequisites

Only users with the Administrators role can set the current alarm threshold warning.

Context

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 rules to move some alarms to the historical alarm list until the number of alarms falls to 90% of the upper threshold.
  • Alarms are moved to the historical-alarm list in the following sequence: cleared alarms, acknowledged and uncleared ADMC alarms, acknowledged and uncleared ADAC alarms, and unacknowledged and uncleared alarms.
  • For alarms of the same type, the earlier alarms are moved to the historical alarm list first.
  • In a distributed system, when the NE alarms are reported to different nodes and the processing of the full current alarm cache is triggered, the alarms are moved to the historical alarm list in descending order of the node alarm quantity. The more alarms are reported to a node, the higher the priority of the node is. For example, if an NE is connected to node A and node B, and the alarm quantity on node A is more than node B, the processing of the full current alarm cache is performed only on node A.

Procedure

  1. Choose Device Management > Alarms Management > Alarm Settings from the main menu.
  2. In the navigation pane, choose Current Alarm Threshold Warning.
  3. Select whether to send an alarm when the number of current alarms reaches the threshold and set the thresholds for generating and clearing alarms.

    • Generation threshold: When the ratio of the number of current alarms to the maximum capacity is greater than or equal to the specified threshold, ALM-157 The Number of Current Alarms Reaches the Threshold is generated.
    • Clearance threshold: When the ratio of the number of current alarms to the maximum capacity is less than the specified threshold, ALM-157 The Number of Current Alarms Reaches the Threshold is cleared. The clearance threshold cannot be higher than the generation threshold.

  4. Click Apply.
