mon_procd service utility syntax

Ubuntu 22.04 LTS z/VM guest

If you run the mon_procd daemon as a systemd service unit, you configure the daemon through specifications in a configuration file.

Where:

start: starts monitoring of guest process data, using the configuration in /etc/sysconfig/mon_procd.
stop: stops monitoring of guest process data.
status: shows current status of guest process data monitoring.
restart: stops and restarts guest process data monitoring.
reload: reloads the configuration. Use reload to re-read the configuration file when it was changed.
enable: starts the service automatically at boot time.
disable: disables automatic start of the service at boot time.

Configuration file keywords

PROC_INTERVAL="<n>": specifies the desired sampling interval in seconds.
PROC="yes | no": specifies whether to enable the mon_procd daemon. Set to "yes" to enable the daemon. Anything other than "yes" will be interpreted as "no".

This example configuration file for mon_procd (/etc/sysconfig/mon_procd) sets the process monitoring interval to 60 seconds:

PROC_INTERVAL=60

Examples of mon_procd use:

To display the status:

# systemctl status mon_procd
| mon_procd.service - Monitor Linux on z/VM
...
   Active: active (running) since Mon 2018-02-26 12:16:00 CET; 4s ago

To display the status again and check that monitoring is now stopped:

# systemctl status mon_procd
| mon_procd.service - Monitor Linux on z/VM
...
   Active: inactive (dead)
...

To restart the daemon and re-read the configuration file:
```
# systemctl restart mon_procd
```
