Nagios Support Forum

hi Vinh,
the issue happen in both aix and linux, so you can test on any system.

i tried your commands and send you attach files.
easy to see when i write a new plugin with sar command inside, the result the same with check on client server.

i assume that ncpa's plugin do not work exact.

thanks.

Hi Hang,
How are you doing?
Sorry, but I'm a bit confuse.
Based on the pictures provided, "sar" gave "Idle %", where as NCPA gave "CPU %" per each CPU (total 16).

"%idle" means CPU is not being used .... it is opposite to "CPU %"
"CPU %" means CPU is being used by users and all those processes in your system.
Have you try writing your own script using either "sar" or "top"? .... since you are thinking they give more accurate results.

Please share your script, when you have it completed.

Also, have you had a chance to try the below script for AIX which I found on Nagios Exchange:
https://exchange.nagios.org/directory/P ... IX/details

Please let me know.


Best Regards,
Vinh

hi Vinh,
Have you ever try the lastest command you sent me?
It will show very details on every cpu, not average, so we can not compare with the last previous (without "sleep5").Don't understand "sleep5" for what?

you can see the result :

check ncpa with &SLEEP=5

check ncpa WITHOUT &SLEEP=5

OK: Percent was 11.02 % | 'percent'=11.02%;20;40;

And how about the TESTCASE2 i sent you? what do you think about it. I guess ncpa's plugin have wrong.

pls find attach file for scripts's details

Hi Hang,
Hope you are having a good day!! ...

I brought this issue up in today group meeting, and here's what their suggestion:

The next step would be to have him create a BR here so he can work with development on it: https://github.com/NagiosEnterprises/ncpa/issues

I'm very sorry, if you think this is a bug, please open a bug report (url above) and work with developer.

As I said before, you can write your own script, then put that under "/usr/local/ncpa/plugins", then use:
./check_ncpa -H x.x.x.x -t 'yourToken' -p 5693 -M 'plugins/yourScript'

Example (oneline) script: If you strongly want to use "sar", you could try the above command.
Please note that the above command was just for you to test out "sar". If you want to use it, you will need to add more condition checking into the script.

Also, if your system have Python's "psutil" installed, you can try this: You can use "pip install psutil" to install "psutil", if you want to try .... just a suggestion ...

ok done.
pls close the topic.

Great!! .... closing thread!! ...
