Nagios Support Forum

Hi Team,

find the below routers as an attachment which are showing down from 106 and 148 days in Nagios tools. I can able to ping these routers from backend and the routers and links are UP from past 2 hrs.why Nagios monitoring is not happening Properly.

Please provide the resolution ASAP along with the possibility reason for the same.

You cut off the status information which is what we would need to see, but it looks like all the ping requests are being blocked. Does the device not respond to a standard ping? It looks like you did some sort of SNMP query instead of a ping.
