SNMP Errors on hardware firewalls



We are a company that does outsourced IT so we use PRTG to monitor client networks and alert us of events such as server downs, low disk space, network traffic, etc.

Recently, we upgraded to version 12 and are quite happy with it. With that, I decided to upgrade our SNMP monitoring to version 3, instead of ye olde V1. That's where my issues start though. Many of my firewalls will give me an error that there is no response from the device. 5 minutes later it is just fine again though.

Knowing that SNMP V3 has a limit on the amount of simultaneous connections/checks, we install a remote probe on a clients server and monitor their network from the inside out. On average, there will be at most 10 sensors on SNMP V3 per remote probe, the rest is all WMI sensors for monitoring servers.

Any idea why my SNMP sensors are still erroring out? I am positive the name/password and such are all correct because if I refresh the sensor once or twice it will then report data (but a different sensor will fail).

Cheers, and thanks in advance for any help!
