On my Nagwin server, I am receiving the following when checking the HDD space on two out of four of my servers. I have one Windows Server 2008 box and the other three are running Windows Server 2003. I am getting this result on two of my Windows Server 2003 boxes, yet the other 03 box returns the correct value.
"DISK OK - usage: C: -5495.8 MB (-536.70% of total 1024.0 MB)"
All of them have identical configurations (winpre version, host.cfg on the nagwin server, nrpe.cfg on the clients). I have verified "check_pdm.exe --disk --drive c:" returns the correct HDD value when exeucted on the server directly. I have also removed and re-added the configurations, but this did not change a thing. Any help would be much appreciated.
If the command runs properly from a dos prompt, then the problem must be related to permissions. Try to give winrpe service account local administrator privileges.
I gave the SvcXinet account administrator rights and restarted the service but this did not change the output.
I forgot to mention in my original post that both of the servers I am having this issue with are Domain Controllers. I have a feeling that has something to do with it. I have again verified that the output from the "check_pdm --disk --drive C: " command is returning the correct result on both servers.
Maybe this information will help pin point the issue as well.
I added the same command (as listed above) to monitor the other volumes on the server. All of these values are being returned correctly to nagios. It is only the C: drive on Domain Controllers that are reporting a negative number.
Thoughts? Suggestions? I'm stuck on this one.
Try to run the plugin in verbose mode (--verbose) and publish results here.
Do you want me to run this argument with the check_pdm plugin on the monitored server? I tried on both the server (check_pdm --disk --drive C: --verbose) and (check_pdm --verbose) and on the Nagios server (check_nrpe -h xxx.xxx.xxx.xxx -c check_pdm_c --verbose), both made no difference in the output. I know I'm entering it in wrong, but not sure where.
If you run check_pdm on the monitored server with --verbose option, it will list WQL command used for getting disk information.
Ok, I have ran the check_pdm command with the --verbose option but no output is produced. Not sure what I'm doing wrong but again, I feel like I'm missing something way simple here.
If you could give me step by step directions, that would be very helpful.
Try double --verbose --verbose to get more detailed info.
I have tried the double --verbose --verbose argument on the monitored server, again, with no results or output being displayed. Would it be possible to communicate through email or setup a time to maybe have you work with me for a few minutes? I keep investing time into this issue and I feel like I'm getting nowhere.
Again, this is only happening on the system drive on DC's. Additionally monitored volumes on the DC are returning the correct results and non DC servers are returning correct results on the system drive.
I'm going crazy here!
I am not sure what i can do here. You say that it works everywhere except your domain controller. This plugins uses WMI and i have no idea why wmi doesn't work on your DC. There may be group policies, user rights restrictions. That may be an access issue (maybe you get better results if you run as administrator).
