9 | # ========================= | ||
10 | # 7-Aug-1999 - Michael Anthon | ||
11 | # Created from check_disk.pl script provided with netsaint_statd (basically | ||
12 | # cause I was too lazy (or is that smart?) to write it from scratch) | ||
13 | # 8-Aug-1999 - Michael Anthon | ||
14 | # Modified [warn] and [critical] parameters to accept format of nnn[M|G] to | ||
15 | # allow setting of limits in MBytes or GBytes. Percentage settings for large | ||
16 | # drives is a pain in the butt | ||
