Device status changed

Hello,

We have issued a problem with our PaloAlto PA-220 firewalls.
We added the firewalls successfully in the NMS with SNMPv3.

After some days we realized, that the firewalls log every 5 to 15 minutes a “device status changed” log.

If i do a snmpget or or snmpwalk everything works fine. Ping also works while LibreNMS shows the device as down.

We have also a PaloAlto PA-820 added in the NMS, this one doesnt make this problems.

Is there any way to se what is logged while LibreNMS is polling the devices?
So i can try to analyse there also.

We think, that the firewalls are so slow, the snmpget or snmpwalk runs in a timeout…

Thank you for your help.
