Windows performance counters

[vhoover]

I am trying to monitor logical disks % of free space via the windows server 2003 r2 (x64) performance counters in Nagios XI. I can get the Nagios to accept the counter, however, it states that 0% is used regardless of what the thresholds are set to. It does not matter it the service check is "OK", "Warning", or "Critical", the data displayed is the same. I run a VBscript on the local box and can see that one is at 52% used. Here is what I have for the service check command:
check_xi_service_nsclient!flidata!COUNTER!-l "\\LogicalDisk[D:\Data1]\% Free Space","Data1 usage is %.2f%%" -w 0.5 -c 0.6!!!!!

Here is the data displayed on the service check:
Data1 usage is 0.00%

What am I doing wrong, or better yet how can this be resolved?

Performance counters can be fickle as they do not always report an error when there is one. It may be that D:|Data1 does not exist. If you change Data1 to something that you know, for sure, doesn't exist, do you still get a 0% usage status?

In addition to what Andy said are you able to get a valid return from this command if you run it from the CLI?:

Code: Select all

/usr/local/nagios/libexec/check_nt -H <windows IP> -p <nsclient port> -s <password> -v COUNTER -l "\\LogicalDisk[D:\Data1]\% Free Space" -w 30 -c 10

I know for sure that Data1 exists but in changing it to Data001 I got the following response:
Data001 usage is 0.00% | 'Data001 usage is %.2f%%'=0.000000%;0.000000;0.000000;

when I ran the following command from the Nagios Server I get a response of "0"
/usr/local/nagios/libexec/check_nt -H <IP address> -p <port> -s <password> -v COUNTER -l "\\LogicalDisk[D:\Data1]\% Free Space" -w 30 -c 10

Essentially what I am trying to do is to monitor mount-points on some windows servers one is 2003 and the other two are 2008. The hard part is they do not have letters assigned they are sitting on a single drive in the case of the 2003 server all 13 mount points are sitting on the D drive.

I get the impression that either:
1. Your mount point or folder name is incorrect
2. The syntax for the performance counter is wrong
3. Or the performance counter does not like in-filesystem mount points.

I finally got this resolved with the following syntax (censored)
check_xi_service_wmiplus!<username>!<password>!checkmountpoint!-a 'D:/Data10/' -w 86 -c 96 -t 60!!!!
Now if I can olny get it to show the results in gb instead of tb, but I am sure that is a change in one of the three files related to the check_xi_service_wmiplus.
