Contribution: quick monitoring script

[aj]

I wrote the following little *nix monitoring script when I needed to
know more about a nocturnal critter that was grabbing too much CPU..
Perhaps you can use it. Just put something like this in crontab and
you're off:

#*/3 01-03 * * * (~/sqllib/db2profile 2>&1 /dev/null ; cd /mydir ;
/mydir/snapshot.sh 2>&1 | mail -s "snapshot" aj)
