Nagios Support Forum

Is there any plugin available for checking DISK IO stat and only RAM(physical memory) instead of MEMUSE which checks virtual memory for windows servers.

Have you considered using windows performance counters to attain this information? Lets see if this would be the right fit for you, run the following from your command line and add values in for "-H" MaxWarn and MaxCrit.. this assumes that you have a C drive on the Windows machine and that you have NSClient++ already installed and configured to send and receive data via NRPE:

To respond on the physical memory question... You can use check_nrpe with nsclient++ and run something similar to this:
Hope this helps.

I see this error in remote system logs

You need a to change a few lines in you nsc.ini/nsclient.ini file if you have not done so already:

Global settings
Under [NRPE] what version of nsclient are you using? We suggest 0.3.9.

Installed nsclient++ version 0.3.9.
uncommented and changed allow_nasty_meta_chars=1

We do not have any nsclient password.


Below is the test result

Do you have the correct ports open on the Windows system? Check for port 5666 and 12489, then run:

/usr/local/nagios/libexec/check_nrpe -H xxx.xx.xxx.xx

xxxx= Nagios IP string, rather than taking time to write the whole check out, we need to make sure that the server's can communicate in the most rudimentary form first.

See paragraphs 5 and 6 located on this page for more information:

I assume 13.129.109.85 is your Nagios XI server's IP. It seems it is not in the allowed hosts. Please, add this line in the NRPE section of the NSC.ini file: Restart the NSClient++ service, so that the changes can take effect and try your check again.

Hope this helps.

We have changed the Ip to new one and gave the same ip in NSC file.Still it is giving same error .

You are putting your Nagios server IP in the NSC.ini correct?

after making changes to the NSC.ini you will need to restart the NSClient++ service
