Issue/Introduction

We have a Cisco switch which can support two PSU (power supply units), but we have only one power supply units on the switch. The snmpcollector probe is generating alerts.

The policy is applied using template and it's configured as follows:

QOS_POWERSUPPLY_STATUS - status

How can we suppress this alert for the time being until we can install the missing power supply unit?

Environment

Release : 20.3

Component : UIM - SNMPCOLLECTOR

Cause

- Guidance

Resolution

Use the nas to either temporarily, automatically, close the alarm, or use a nas preprocessing rule to exclude (delete) the alarm. Try using a regex for the message filter, e.g.,

   /.*QOS_POWER_SUPPLY = 1.0.*/

For example,

Alarms can be preprocessed and filtered using other field values if need be, by adding some other filtering such as the robot name, etc.

- Created a nas preprocessing rule to exclude the missing power supply alarms from 2 source robots:

Sources:

tx1-xxx-abc-xxx-01 ca1-xxx-abc-xxx-01

Message filter:

/.*QOS_POWER_SUPPLY = 1.0.*/
