Nagios setup & systemd

English Install/Boot/Login

Hi All,

Trying to setup nagios to monitor my network, I have everything installed from YaST, and have edited the config files as needed.

I have enabled the service with systemctl enable nagios
However when I attempt to start nagios with systemctl start nagios and then check it’s status with systemctl status it seems to shutdown immediately :frowning:

This leads to the web interface not working correctly.
running the ExecPre command (/usr/sbin/nagios -v /etc/nagios/nagios.cfg) reports no warnings or errors.

Manually running the ExecStart (/usr/sbin/nagios -d /etc/nagios/nagios.cfg) results in several nagios processes being launched and the web interface works.
So it seems there is a problem with the systemd file.

Does anyone have any idea how I may fix this?
Note: other than enabling it, I’ve not touched the systemd unit file.

Cheers.

Phill.

Can you also check the Nagios Core logs located at /usr/local/nagios/var/nagios.log?

No file there, I installed from Yast, not from source. Log file seems to be at :
/var/log/nagios/nagios.log

And after attempting to start and shutting down it’s empty. (Having first cleared it so as to only capture start / shutdown messages).

Cheers.

Phill.

After compairing the unit file to one on a Rocky 9 system at work, I have found that adding :

Type=forking

To the systemd unit file and doing a systemctl daemon-reload fixed the problem.

Cheers.

If you use openSUSE package from the default repositories, you should open bug report.
