assistance for auto start of xymon in Rocky 9 🔗 link

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

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 Josh

 

 

Yes I did

 

I have followed those to the letter and I still have only the server starting, and no client data being sent

 

It is really peculiar that it does not work on the newer machine

 

Forgive me for not responding earlier as I do appreciate any help or input given

 

Thanks

 

David

The only different in Tom's post and the Terabithia package is the ExecStart xymonlaunch binary location FWIW (I'm using Alma9).

Hi Tom

 

I  checked the file, it exists, and was full of cant find netstat.

 

I highly suspect my issue is that I built my machine with one name (vms1m-xymon.our.domain), and to satisfy the management gods I made a dns alias for the old machine I was migrating from (vmsg-xymon1.our.domain). This is just so that some folks do not have to change favourites in their browsers ( goodness knows how they got on when twitter changed to X)

I then had to crock a bunch of stuff on new machine to make it look as if it had a different name, and I must have some sort of error in there.

 

Thanks

 

 

David

David,

     Have you checked to see if there are any errors in the /var/log/xymon/xymonclient.log file?  This file is created by the xymon client.  If there are no errors, this file may be empty or non-existent.

 

Tom

Can I see a copy of the contents of one or both of those EnvironmentFiles?

I'm dealing with a very similar issue and it seems to be related to the
environment variables not being populated and things that depend on them
failing.

E.g. using a full path in place of $XYMONCLIENTHOME in clientlaunch.cfg
helps.
