Nagios Support Forum

I have searched everywhere for a fix for a problem with NRDS. We have implemented NRDS data sender on 5 servers located in a secluded environment from our Nagios XI Server, and all is working fine except one portion.
4 of the 5 servers are running Server 2008 R2, and they are not correctly returning the CPU utilization - the checks always just return the result of 0%.
I have tested this on the actual servers via an RDP session and running the cmd command, and get the same results of 0% utilization regardless of the load on the CPU, and all other checks such as RAM work fine.
I have tried monitoring the CPU via two different plugins that come with NRDS: check-pdm.exe & cpuload_nrpe_nt.exe

The default command that was set during the NRDS setup was cpuload_nrpe_nt.exe, and this is working fine on the 5th server, which is running Server 2012, however there is a bug preventing it from returning correct results on a 2008 OS.
Please help!

Thanks,

What happens when you run these commands at a command line on these servers?

Command: cpuload_nrpe_nt.exe 90 95
Results: NOW: Mean:0.000000% Variance: 0.000000% CUMULATIVE: Mean:0.000000% Variance: 0.000000%

Command: check_pdm.exe --processor
Result: PROCESSOR OK - usage 0.00%|'processor usage'=0.00%;;;

These were both run from an administrative command prompt while cpu was under a 30%+ load.

It seems like this is a bug. I was able to recreate the issue and I filed an internal bug report to our system (TASK ID 6208).

Great! Thanks for your help! Will you be posting any updates here?

Most probably not as this is an internal task. However, you can always inquire about TASK ID 6208, and ask for updates. Thank you!

What is the best way to inquire on the status of a task? Through an email?

Feel free to just ask us about the task ID on the Nagios Forums - any tech can check on the status for you.

Is there any update on this task ID yet?

I've not seen it assigned to anyone as of yet, and there are no notes as to any progress. Unfortunately once it is in the devs' hands it is out of ours, so we have little influence over what gets changed and when.
