Hi!

I have Nagios 3.5.1 running on CentOS 6.7

I run command ps aux in command line and got output (just part of command output related to nagios):

My question about line (reading main config):
nagios 46338 0.0 0.0 205680 1844 ? S 14:32 0:00 /usr/sbin/nagios -d /etc/nagios/nagios.cfg

Should I have so many processes related to main config reading? Is it normal? I didn't remark this before.

Thank you

That does seem to to many nagios processes running.
If you stop the nagios processes and kill off the extras, do they come back when you start the pagios process?
If so, can you post your nagios.cfg file so we can check it?

I killed all nagios processes.

Looks like it's better now

and one more

when I put ps aux | grep nagios on watch

# watch -n2 'ps aux | grep nagios'

periodically I have the next line in output (not constantly)
nagios 35591 0.0 0.0 0 0 ? Z 16:24 0:00 [nagios] <defunct>

Actually it is just one Zombie so I don't really care about this defunct process

The zombie process should be just a worker shutting down so that is normal.
Nothing in the nagios.cfg file looks wrong so keep an eye on the server and let us know if we can close this post.

actually my question is - how many lines like underneath are acceptable? :
or another words - when this process created?
nagios 21146 0.1 0.0 205708 2660 ? Ssl 15:50 0:09 /usr/sbin/nagios -d /etc/nagios/nagios.cfg
because periodically I have 5-9 such lines in ps output, after a few second - just one

When the server is not checking anything, there should be 2 processes running. One parent and one child.
When the server is busy, it will spawn more of them as needed and that number depends on how many checks are running at that moment, time it takes to run, etc.. but as long as they startup and shutdown, that number should be alright.

OK, thank you for you help

We can close the thread I guess
