kleines perl script umbauen
ich hab hier ein perl script vom nagios projekt. damit wird der freie speicher eines shares überwacht.
die ausgabe schaut in etwa so aus:
Code:
Domain=[Work] OS=[Windows 5.0] Server=[Windows 2000 LAN Manager]
Disk ok - 2.92G (73%) free on \\192.168.0.1\hdiskc
nun möchte ich schöne grafiken über den verbrauch des freien speichers diverser shares in cacti einrichten, dazu benötige ich aber einen reinen zahlenwert. es muß nicht unbedingt dieses perlscript sein, eine lösung als shellscript/php würde es auch tun.
hier das perl script, ich habe es auf 2 threads aufteilen müssen:
Code:
#! /usr/bin/perl
#-wT
#
#
# check_disk.pl <host> <share> <user> <pass> [warn] [critical] [port]
#
# NetSaint host script to get the disk usage from a SMB share
#
# Changes and Modifications
# =========================
# 7-Aug-1999 - Michael Anthon
# Created from check_disk.pl script provided with netsaint_statd (basically
# cause I was too lazy (or is that smart?) to write it from scratch)
# 8-Aug-1999 - Michael Anthon
# Modified [warn] and [critical] parameters to accept format of nnn[M|G] to
# allow setting of limits in MBytes or GBytes. Percentage settings for large
# drives is a pain in the butt
