Can someone please point me in the right direction on how to notify when a node is pingable but solarwinds is unable to get an SNMP response. I'm running NPM 10.1
Probably the best way would be to write a custom SQL alert that looks for something that we should always have, like SysObjectID and alert if it ever returns null.
This is probably 10 years too late, and based on a thread I found by @kaotic for creating a report with a similar query.
Adding an SQL alert with query:
WHERE ((DATEDIFF(mi, Nodes.LastSystemUpTimePollUtc, getutcdate()) > 120) AND (Nodes.Status = '1'))
has the desired result.
