SNMP Troubleshooter

There are devices with no alerts beyond warning for "No Data" that are monitored primarily off of SNMP polling. I have discovered a device in which SNMP hasn't been functioning with SNMP for months and it has major implications for us.

We really could use a "SNMP Troubleshooter" that functions much like the vendor specific troubleshooters that already exist. To name one specifically, the VMware_LM_Troubleshooter.

I'm honestly a little worried of how many devices will end up triggering from this once it's enabled, but it would be a great tool to ensure we are monitoring what we are expecting to be monitored.

We have standard rules for this that rely on the no-data alert for the uptime datapoint, which otherwise has no alert thresholds. Finding which datapoint is appropriate is harder than it ought to be and I agree a dedicated troubleshooter DS would greatly simplify things.  Right now we have several alert rules per client to capture the problem adequately.

FWIW, here are our catchall rules for those and similar items.
