[Nagiosplug-help] check_nrpe CheckWMIValue help

[Louis Carreiro]

Hey everyone! I've got a problem that I've been banging my head against the
wall about. I'm trying to pull in performance data using "check_nrpe
CheckWMIValue" and I'm getting no where.

I've got a pretty standard Nagios install. Ubuntu 10.04, Nagios 3.2.2,
Plugins 1.4.15, NRPE 2.12, MRTG, NSClient++ 0.3.8, and NagiosGraph.

My command.cfg looks like this:
[code]
# 'check_nrpe' command definition
define command{
        command_name    check_nrpe
        command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
        }
[/code]

My service definition looks like this:
[code]
define service{
        use generic-service;
        host_name 172.28.200.7
        service_description     C Drive Read IO;
        check_command   check_nrpe!CheckWMIValue -a "Query=Select Name,
DiskReadsPersec from Win32_PerfFormattedData_PerfDisk_PhysicalDisk WHERE
Name like \'%C:%\'"  Check:DiskReads=DiskReadsPersec MaxWarn=0 MaxCrit=100
AliasCol=Name;
        action_url
 /nagios/cgi-bin/show.cgi?host=$HOSTNAME$&service=$SERVICEDESC$'
onMouseOver='showGraphPopup(this)' onMouseOut='hideGraphPopup()'
rel='/nagios$;
        }
[/code]

WIth that, all I get in Nagios is:
[code]
Status Information: OK: Everything seems fine.
Performance Data:
[/code]

The performance data is blank. If run check_nrpe from the command line with
the arguments listed above, I get:
[code]OK: Everything seems fine.|'DiskReads'=0;0;100; [/code]

When Nagios builds the macro, it looks like it processes fine. Below is the
Nagios.debug:

[/code]

I'm completely lost!!!! It looks like it's processing the macros correctly.
If I run check_nrpe with the arguments in the command line it works
correctly. It's just when Nagios processes the command it doesn't receive
the performance data. It's like it's dropping the end of completely. I know
if you omit the MinCrit and MaxCrit it won't display the performance data
but I have those in there. The macro processing even keeps it. It just seems
like when Nagios executes the command, it drops them or something. Does
anyone have any thoughts?

Thanks in advance everyone!

Louis
