Reading the script, it looks like it is comparing the FREE percentage
against your threshold, so your thresholds are probably the inverse of
what you really want:
If InStr(Wscript.Arguments.Named("w"),"%") Then
Your plugin call means "warn me if there is less than 85% free" (15%
full) and "it's critical if there is less than 90% free" (10% full), so
it's working as designed.
I did the same thing when I first started using the check_disk plugins
(unix and windows).
As a side note, we have been talking about changing the plugin argument
style (at least for the unix plugins) to be something like this in
meaning, it's OK if the drive is between 30 and 80 % full, WARN if
80-90% full, but otherwise return critical.
We're hoping that will be easier to get right the first time :)
