Nagios Support Forum

We are experiencing constant abnormalities in my Nagios server.

I have configured host and services of multiple clients of multiple location through NCPA and all hosts(which are virtual machines at the backend) are communicating through NCPA agent for both Windows and LINUX(mostly CENTOS) of 64-bit OS.

What we are facing from some days is that hosts and services shows down at NAGIOS XI some shows socket time out or some shows service check time out but when we chcek the host by accessing them, NCPA service must be running fine on the host they are reachable at that time but shows down on nagios xi and triggering the alerts and no latency is also there in accessing the host from within the nagios server.

Tried changing service check time out parameter but still issue persists, kindly help me in finding the root cause.

Hi @riya_g2,

How are you determining that the hosts marked as down in XI are reachable at that moment? Are you sure they aren't going down and then recovering before you can check?

If it is in fact just going down and you would like to avoid false positives in XI, you can change the check settings in the host's config.

Let us know what you find.

Thank you!

Also it may help if you post the exact text of the error.
