I know it is an old thread, but I was trying to solve the same issue, and was not able to find a solution.

After going through check_wmi_plus.pl code and experimenting, I was able to get it right.

Get Warning and Critical when free space drops below certain number of GB instead of percentage.


in example mentioned

Command view
$USER1$/check_wmi_plus.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -m checkdrivesize -a "$ARG3$" -w _FreeGB=$ARG4$ -c _FreeGB=$ARG5$ $ARG6$

ARG3=C|D|E|Q|H|I|L|M|N
ARG4=5G
ARG5=4G

5G and 4G need to be appended with colon
so part of the string will look something like

according to this

EXAMPLE RANGES
This table lists example WARN/CRIT criteria and when they will trigger an alert.
10 < 0 or > 10, (outside the range of {0 .. 10})
10: < 10, (outside {10 .. infinity})
~:10 > 10, (outside the range of {-infinity .. 10})
10:20 < 10 or > 20, (outside the range of {10 .. 20})
\@10:20 = 10 and = 20, (inside the range of {10 .. 20})
10 < 0 or > 10, (outside the range of {0 .. 10})
10G < 0 or > 10G, (outside the range of {0 .. 10G})

Thanks for sharing and glad to see this got straightened out! Did you have any other questions or may we lock this thread, seeing it is 1,100 days running?

Hi,
I've just tested the following syntax in my template and apply it to a service
It doesn't work :

Try wrapping the $ARG3$ value in single quotes. I tried the following, which worked for me:

Hi,
I tried the following with command $USER1$/check_wmi_plus.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -m checkdrivesize -a "$ARG3$" -w _FreeGB=$ARG4$ -c _FreeGB=$ARG5$ $ARG6$ :
$ARG3$='C:'|'D:'|'E:'|'Q:'|'H:'|'I:'|'L:'|'M:'|'N:' doesn't work
$ARG3$='C:|D:|E:|Q:|H:|I:|L:|M:|N:' doesn't work
$ARG3$='C|D|E|Q|H|I|L|M|N' doesn't work

$ARG3$=C:|D:|E:|Q:|H:|I:|L:|M:|N: works with command $USER1$/check_wmi_plus.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -m checkdrivesize -a "$ARG3$" -w $ARG4$ -c $ARG5$ $ARG6$

I tested the following scenario - in my command, $ARG4$ is NOT wrapped in quotes, and in the $ARG4$ field I have -a 'C|D' -w _FreeGB=5G -c _FreeGB=4G, which seems to work fine.

Hi,
I tried your configuration : (please see the attached screen capture)

$ARGG$4=-a 'C|D|E|Q|H|I|L|M|N' -w _FreeGB=10G -c _FreeGB=5G

Here's the result of test command on a host having a disk size problem :

COMMAND: /usr/local/nagios/libexec/check_wmi_plus.pl -H xxxxxxxx -u domcompta/svc_riverbed -p dsisvc -m checkdrivesize -a 'C\|D\|E\|Q\|H\|I\|L\|M\|N' -w _FreeGB=10G -c _FreeGB=5G
OUTPUT: UNKNOWN - Could not find a drive matching 'C\|D\|E\|Q\|H\|I\|L\|M\|N' or the WMI data returned is invalid. Available Drives are C:, D:, E:, F:, M:, N:

The test check command will not act as a regular Nagios check would due to escaping and permissions. When the check runs it's full course, does it work successfully, or what error do you see?

Hi,
You're right, the test doesn't work but the check works, so you can close the post.
Thanks,

Frederic

Glad to hear it is resolved. I am going to lock the thread. Please feel free to post again if you have you another issue. Thank you for using the Nagios forums!
