Nagios Support Forum

I'm investigating a Weird situation: from time to time we bump with a screen that says "maybe this page is inactive or might been moved" (original Message in Spanish).

we use Nagios Core 4.4.5 o Centos 7.6 and our Browser is Chrome

How many hosts/hostgroups/services/servicegroups do you have configured on the system, and what are the hardware specs of the machine?

We have 150 hosts, organized in 8 groups. We have about 400 services monitored.

We run Nagios Core 4.4.5, on Centos 7.7. We run it on a VM with 2 CPU, 2 GB RAM.

Do you load the page by IP address or hostname? Is there a possibility that the hostname isn't resolving?

It is also possible if someone or something restarted the apache process this could happen, is there any correlation to the time the apache (httpd) process was started to when this happens?

The page is loaded by it hostname. Name resolution seems to work fine. This happens from time to time, and no apache restarts are related.

It would be interesting to see if this would happen at all if loaded by IP, it would rule out possible DNS issues. For example, one of the DNS server not able to resolve the hostname
