try man du. It will give you file sizes of all the files in a directory
tree, which you can then pass to sort and head to pull out the biggest
offenders, like this
# cd /
# du | sort -rn | head -10
for monitoring my system, I use tripwire, but that might be a bit much
just for watching disk usage. Try putting a "df -h" in your periodic
scripts to have the output of that command mailed to you each day.
