Below is what I have on Rocky8 and Rocky9, and both the server and client startup fine for me.  Update the path to xymon appropriately for your installation.

Hi

 

I am looking for some clues to autostart xymon in Rocky9

 

I copied my method from a Centos 7 box which has been running successfully for quite a number of years

 

I made a xymonlaunch.service file which I placed in /etc/system/system, contents below

# xymonlaunch.service

# systemd file for Fedora 18 and up, or RHEL 7 and up

 

[Unit]

Description=Xymon systems and network monitor

Documentation=man:xymon(7) man:xymonlaunch(8) man:xymon(1)

After=network.target

 

[Install]

# Compatibility with "xymon" and "xymon-client"

Alias=xymon.service

Alias=xymon-client.service

WantedBy=multi-user.target

 

[Service]

#EnvironmentFile=/etc/sysconfig/xymonlaunch

User=xymon

# We wrap in xymoncmd to eliminate the need for the bulk of the old init script

ExecStart=/opt/BB/bbsw/server/bin/xymoncmd /opt/BB/bbsw/server/bin/xymonlaunch --no-daemon $XYMONLAUNCHOPTS

Type=simple

 

# Kill xymonlaunch, but don't send kills to the underlying procs, since they

# might be doing important things (like writing checkpoints and flushing caches)

KillMode=process

# SendSIGHUP=yes

SendSIGKILL=no

 

I then did systemctl enable xymonlaunch.service, and this made 2 symbolic links in the same directory one named xymon.service and one named xymon-client.service

 

What is happening on Rocky9 is that on the server is being started, the client part does not start

 

Any ideas what may be awry? The same method worked/works without issue on Centos 7

 

 

Any help, guidance, clues would be much appreciated. I know that I would be able to cobble something together to stick into rc.local, but the powers that be up above would rather I did it using the method that uses systemctl

 

 

Best regards

 

David
