Here is what I got when I did ps -ef | grep bin/nagios: (seems like double services)

Code: Select all

I did killall nagios and then got:

root     14334 14085  0 09:30 ?        00:00:00 grep bin/nagios
Should I expect there to be nothing running with the name nagios? no matter how many times I try to do killall nagios it's the same.

What should I do?

Thanks

Having 2 nagios processes is a normal thing. We do not count the workers as a process.
Here is your parent process

Code: Select all

nagios   14317 18969  2 09:30 ?        00:00:00 /usr/local/nagios/bin/nagios /usr/local/nagios/etc/nagios.cfg
And here is the child process

Code: Select all

nagios   14330 14317  0 09:30 ?        00:00:00 /usr/local/nagios/bin/nagios /usr/local/nagios/etc/nagios.cfg
The issue was your system you had multiple parent / child processes and that causes issues but they look correct now after the killall command was run.
