    Making incorrect changes to a configuration file can cause serious system errors. Before you start, back up tmsplx.xml in case you need to restore your original settings.
  2. Add the following lines to rotate logs:
    /var/log/messages /{path}/{splxlog} {
    sharedscripts
    postrotate
        /usr/bin/systemctl kill -s HUP rsyslog.service >
/dev/null 2>&1 || true
    endscript
}
  3. Save and close the rsyslog file.
