tried the steps on the following link ==>

What is the output of:
?

I got that working. I was able to install Nagios. I did a restore, but the problem I am seeing now is that the monitoring engine doesn't seem to be running

everything seems green.

I am using Mod_gearman, and mod_gearmand is running including the worker.

I dont see jobs running.

I tried disableling mod_gearman module from the nagios.cfg but I see the same result. So mod_gearman doesnt seem to be creating the problem

What data are you seeing in the nagios.log when you restart the nagios service?

No Errors

what I notice is that when I stop and start nagios. I see stuff flowing. I see JOBs running, but then all stops. but again, everything seems to be running, and I dont see anything on the logs. i.e. nagios.log, mysql, ewtc

This is odd that this is happening twice. can you share your nagios.cfg ?

good catch

I had these lines twice. at the top and bottom

broker_module=/usr/lib64/mod_gearman2/mod_gearman2.o config=/etc/mod_gearman2/module.conf eventhandler=no

removed the line, but unfortunately I still see the issue

restarting Nagios seems to help for few minutes. I see jobs running in garman_top2, then after few minutes everything stops.

Is it possible to comment out the other mod_gearman line and run the checks locally to verify it's not a problem with your version of mod_gearman?

I tried that already. that was one of the first things a I did

I meant so neither are running, just Nagios Core with no mod_gearman

Also can you post the output of the following
