NetXMS Support Forum

Hi guys,

I am getting an alarm as below from one of my switch in the network.

"Status of DCI 7073 (SNMP: .1.3.6.1.4.1.2021.11.11.0) changed to UNSUPPORTED"

Do you know what it is and what to do to clear this alarm?


Thanks

That's a standard OID for CPU usage (more precise for "CPU Idle").

The unsupported alert means that you have a DCI on your node that tries to query the above OID and NetXMS isn't getting a response back.
That could be because:
- the device really doesn't support that OID
- the device is currently unreachable but NetXMS hasn't worked that out yet
- the device is having a temporary issue dealing with the request
- some SNMP packet(s) got lost in transit
If it's a temporary issue, the DCI should at some point change back to supported.

At our end, we simply disabled the event processing policy for unsupported DCIs as we are making heavy use of templates and some devices not supporting some DCI happens often enough to make unsupported DCI events a nuisance that drowns out other alerts. It really depends on your setup though.

Tursiops,

Thanks for the detail explanation.

That's been really helpful.
