Hi,
Following my case Case Update: 346091 - FEATURE REQUEST: Indicate if a device is not responding to SNMP.
I post in the forum my request.
We have some device that do no more respond to SNMP query due to a change in their configuration.
In NPM the monitored interface are with the status Unknown because NPM can't query the device, but for the other value : CPU, Memory, volume we still have the last polled value.
Nothing really indicates that the devices is no more SNMP reachable.
So that we are requested an indicator or something else that can tell us if we have devices that do not respond to SNMP, because we can't rely on the wrong information displayed in the interface.
Cheers
