As I have had those mouse syslogs filling up /var which cripples anything that
touches logs, mail, runs, pids, in other words, everything. So a monitor like
this would be very useful. The monitor would need to check partitions in a
conf file and then take action if any are filled. In the case of /var,
messaging, mailing, most anything will not work unless I set the limit low
enough. But that's the whole point.
Maybe post your perl.
