Nagios Support Forum

I'm trying to install NCPA on Windows Server 2012 R2. It doesn't seem to be working. The only other post I could find on the forum with the same issue ended with the user switching to another agent. Anyone know how to fix this, or if Windows Server 2012 R2 is even supported in NCPA? This is a new install, have not touched or changed the cfg file.

What is the NCPA version that you are currently using? I believe you need to run: "diskperf -y" command to on the Windows box to fix this problem. In any case, the issue has been fixed in NCAP ver. 1.7.1. See the change log:

https://github.com/NagiosEnterprises/nc ... CHANGES.md

You can download it from here:

http://assets.nagios.com/downloads/ncpa/download.php

Using 1.7.1. Just in case, tried to run 'diskperf -y' anyway, and got a notice that "Disk performance counters are permanently enabled on systems beyond Windows 2000."

Any other ideas?

I've also tried 1.7 and 1.5 just to make sure they didn't help, and had similar issues.

Just to give you heads up - I was told by our developers that they will be releasing NCPA ver. 1.7.2 very soon - most probably tomorrow. These issues *should* be fixed in 1.7.2.

Sounds good, thanks. I'll wait till 1.7.2 comes out to do more testing.

I also was getting this error and figured there was a clue in the output

So I went and downloaded Python 2.7 (from https://www.python.org/download/releases/2.7.8/) and installed it into the folder suggested.

Is Python a prerequisite?

Then I reinstalled, and it went through ok.

Yes, NCPA is driven by python, though the installer should take care or the pre-reqs for you which I believe is the issue here.

Just installed 1.7.2 and everything seems to be working. Thanks!

Correction:
1.7.2 only works if I first run 'diskperf -y', and then run the installer. Otherwise the service doesn't install correctly and I still get the disk error. It's working enough for me to use though. Thanks!
