[Xymon] journalctl support for RHEL/Alma Linux 9

[Lists]

Hi everyone, 

I've been introducing a few AlmaLinux 9 hosts into my monitored network. I'm happy to share my 
build notes, so far, but specifically am wondering about "msgs" monitoring - it does not seem 
that journalctl is supported?

EL9 install notes below 

COMPILING: EL9 (CLIENT ONLY) 
1) yum -y groupinstall "Development Tools" 
 yum install pcre-devel 
 useradd xymon 
2) cd /usr/src 
3) ./configure --client 
 DON'T FORGET TO PUT IN THE RIGHT SERVER IP!! 
4) ./make 
5) tar -zcf xymon.client.not.installed.el9.tgz 
6) scp xymon.client.not.installed.el9.tgz root at monitor:/var/www/html/. 


INSTALLING CREATED CLIENT 
1) Verify the hostname matches xymon server config 
hostname # set as necessary: 
hostnamectl set-hostname $HOSTNAME 

2) Run the following 
cd /usr/src # NOTE THE VERSION!!  
wget http://monitor.effortlessis.com/xymon.client.not.installed.elVERSION.tgz 
tar -zxvf xymon.client.not.installed.tgz 
useradd xymon 
yum install libtirpc libtirpc-devel 
yum groupinstall "Development Tools" (if needed) 
cd xymon-4.3.30 
make install 

3) Verify it works 
su - xymon 
xymon --debug # make sure it runs ok - WHAT DOES THIS DO? 

4) yum groupremove "Development Tools" (if installed just for this) 

./runclient.sh start # wait a few minutes  
# see it on the server:  
http://monitor.effortlessis.com/xymon/ 

run xymon directly to see it works. As user xymon on client

4) Make it work via init. 
cp -av /root/repo/xymon/xymond /etc/rc.d/init.d/xymond4) 
ln -s /etc/rc.d/init.d/xymond /etc/rc.d/rc3.d/S99xymond; 
cd /etc/rc.d/init.d; 
chcon --reference=functions xymond 
systemctl enable xymond; 
systemctl start xymond; 

4a) Make it work via systemctl ## not done yet  


5) Common issues: 
A) /var/log/messages 
 chown root.xymon /var/log/messages; 
 chmod g+r /var/log/messages 
B) on xymon server, edit procs 
C) SELinux error on start xymond via systemctl  ( ??? WTF IS THIS? )
