Hi,

You need to create something like this :  (ignore the colours)

You want to alert when status_name = false (the translated value from the device) and match the cisco-stackwise-redundant-state status type attribute in the associations.

At the moment it doesn’t seem like the entity system for status understands the mib/oid attributes, I’ll have to look at that, otherwise you’d have matched it that way instead of the older “type”. MIB/OID is shown in the status table where it’s known.

You can get the type by guessing, since it’s usually obvious, or checking in the poller output :

Subject: [Observium] Alert Check - Monitoring Cisco Stack Redundancy

Hello,

I was wondering if anyone could help me write a better alert checker to determine if a Cisco stack has a missing member.  Occasionally, one member of a stack will fail, but the stack continues to operate so it's not in a "down" state.  I would like to get a notification when that happens.

I am currently monitoring all stack ports, but any unused stack ports show "down" as well, so I'm looking for a better solution.

I would like to use another status indicator such as "stack is redundant" or "stacking state":

Perhaps cswRingRedundant ?

Could anyone assist me with how to construct an alert check to accomplish this?

Thanks!
