How are Ubuntu users configuring Xymon to monitor any log files? I just installed 18.04.1 LTS.

Are you modifying Xymon's client-local.cfg file to match whatever OS Ubuntu is sending to Xymon or are you modifying the rsyslog config files to generate a /var/log/messages file?

Aside - Wish this was configured ahead of time as a part of the Ubuntu Xymon packages.

After installing the Ubuntu Xymon packages, Xymon is matching an OS configured to monitor /var/log/messages in the client-local.cfg file.

However, the stock Ubuntu distribution does not generate a /var/log/messages file.

According to the /etc/rsyslog.d/50-default.conf file, Ubuntu by default generates these log files:

Default rules for rsyslog.

For more information see rsyslog.conf(5) and /etc/rsyslog.conf

First some standard log files. Log by facility.

auth,authpriv.* /var/log/auth.log *.*;auth,authpriv.none -/var/log/syslog #cron.* /var/log/cron.log #daemon.* -/var/log/daemon.log kern.* -/var/log/kern.log #lpr.* -/var/log/lpr.log mail.* -/var/log/mail.log #user.* -/var/log/user.log

Logging for the mail system. Split it up so that

it is easy to write scripts to parse these files.

#mail.info -/var/log/mail.info #mail.warn -/var/log/mail.warn mail.err /var/log/mail.err

Some "catch-all" log files.

#*.=debug;\

auth,authpriv.none;\

news.none;mail.none -/var/log/debug

#*.=info;*.=notice;*.=warn;\

auth,authpriv.none;\

cron,daemon.none;\

mail,news.none -/var/log/messages

Emergencies are sent to everybody logged in.

*.emerg :omusrmsg:*

I like to have messages displayed on the console, but only on a virtual

console I usually leave idle.

#daemon,mail.*;\

news.=crit;news.=err;news.=notice;\

*.=debug;*.=info;\

*.=notice;*.=warn /dev/tty8

Another option would be to create a file like /etc/rsyslog.d/xymon.conf

consolidate logs into single file for Xymon to monitor

*.=info;*.=notice;*.=warn;
auth,authpriv.none;
cron,daemon.none;
mail,news.none -/var/log/messages

If that would be agreeable, it could conceivably be included in the Ubuntu Xymon packages.
