Issue/Introduction

How can we hide a specific alarm for a specific device.

We don't want to see the “BAD LINK DETECTED” alarm from devices that contain “accx” in the name.

kcb7k2accx26
kcb7k2accx241

For any other device we still need to have the alarm.

We created the following expression, but it is not working.

Cause

We are working as expected. 

Here we are performing on negation, i.e. (!A & !B), but our requirement is to do !(A & B).

Environment

Release : 10.3

Component : Spectrum Alarm & Event Management

Resolution

We want to hide (negation) the alarms matching the condition of "(cause code == xxx) & (name == abc)"    i.e.    " ! ( (cause code == xxx) & (name == abc) ) "

But !(A & B) = (!A | !B), but not equal to (!A & !B).

Symbols Meaning :

! => Negation
& => AND
| => OR

 

So we need to create a filter something like below, to filter/hide out the Alarms matching with a Cause Code and Name.
