Symptom: snmp probe alarms-> "The SNMP agent at <IP/Host> is not responding."

Configuration file size:

There is a 3MB limit on the size of the snmpget configuration file. When the configuration file size gets close to or over this limit you may see performance issues.

Number of OIDs per profile:

There is a 299 OID limit per profile.

Timeouts/Retry 'default' settings:

We have seen cases in the past where a default setting for either timeout or retries actually defaults to either a very low number or even 0 so we recommend setting the probe timeout and retries for each profile to 10 and 2 respectively and this can be done via bulk configuration if necessary.
