Hi,  as xinetd is not provided for RHEL 9, I wrote a couple of systemd units to make this work.  I am sure someone smarter than me could make this better, but I have confirmed this does work on any modern systemd implementation.

Would it be possible to get this in the documentation so the knowledge is not lost?

Here is the info:

Create a new file: /etc/systemd/system/observiumagent.socket

Paste this into the file:

[Unit]

Description=Observium Agent Socket

Requires=observiumagent@.service

[Socket]

ListenStream=36602

Accept=yes

[Install]

WantedBy=sockets.target

Change permissions on the file: Chmod 660 /etc/systemd/system/observiumagent.socket

Create another new file: /etc/systemd/system/observiumagent@.service

Paste this into the file:

[Unit]

Description=Observium Agent Server

PartOf=observiumagent.socket

[Service]

ExecStart=-/usr/bin/observium_agent

#User=example

#Group=example

StandardInput=socket

Sockets=observiumagent.socket

Change permissions on the file: Chmod 660 /etc/systemd/system/observiumagent@.service

Reload systemd: systemctl daemon-reload

Enable and start the service: systemctl enable --now observiumagent.socket

That’s it, of course, follow the rest of the direction on the page (UNIX Agent - Observium), just ignore the ones involving xinetd

Thanks
