NSClient++ Help (#1) - performance data of CheckDriveSize (#542) - Message List

Hi, I'm new to Nagios and NSClient++. I use NSClient++ version 0.3.8.19 2010-02-28 to check the disks of Windows servers. I use the following alias_disk:

alias_disk=CheckDriveSize MinWarnFree=20% MinCritFree=10% CheckAll FilterType=FIXED

If I execute

/usr/lib/nagios/plugins/check_nrpe -H abf024 -c alias_disk

I get the following output:

OK: All drives within bounds.|'C:\ %'=89%;20;10; 'C:\'=8.81G;14.90;7.45;0;74.5; 'D:\ %'=99%;20;10; 'D:\'=416.63M;7852.07;3926.03;0;39260.37;

Disk C: has a total of 74.5 GB and 8.81 GB are used.

If I look to the % values they look allright. They say 89% are free which is o.k.. But the absolut values show 8.81G which is not the free space, it is the used space! On the other hand the warning and critical values show the free space. This makes troubles to display a correct graph with PNP4Nagios.

Is this a bug?
