I have a problem with one of cisco router, snmp sensors changes status from warning to up with every request.
For example,

20.12.2019 8:48:52	System Health CPU	Up	
4 %
20.12.2019 8:39:06	System Health CPU	Warning	
No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (SNMP error # -2003)
20.12.2019 8:29:07	System Health CPU	Up	
4 %
20.12.2019 8:29:06	System Health CPU	Warning	
No response (check: firewalls, routing, snmp settings of device, IPs, SNMP version, community, passwords etc) (SNMP error # -2003)
20.12.2019 6:59:13	System Health CPU	Up	
5 %

Ping sensor is ok, but all snmp sensors have the same behavior. I tried to recreate sensors and device, but the problem presents

cisco no-response snmp

Hi there,

Since it seems that every second scan fails here, maybe the device is having issues to those requests in time I would recommend to try a higher scanning interval and a higher SNMP timeout in the device settings.

Please let us know if the issue persists afterwards.


Kind regards,
