| 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 | ||
