check_nagios and system log

Hi,

I'm running two Nagios-Boxes which should monitor themselves. Server A
monitors Server B and viceversa. I'm using check_nagios, executed remote
via ssh. This setup works fine, check_nagios looks for one or more
running nagios processes and for an entry in the system log not older
than 5 minutes.

This is a perfect solution to monitor if nagios is still working
correctly - almost. Nagios only logs if there is an issue with a
monitored service or an user action. But in a perfect world there isn't
any entry.. ok, in my world there is an entry, but not every five
minutes. So check_nagios reports "NAGIOS WARNING: 1 process, status log
updated 1379 seconds ago".

Is there an option to enable a "I'm still alive!"-entry in the logfile
each minute or so? Or is there a more gentle way to monitor if nagios is
working fine?

Regards,

Falk
