Change output to KB or MB..

[xerez]

Hi, I want monitor the memory usage of a process. I run the following:

Code: Select all

[nagios@hostname libexec]$ ./check_nrpe -H [IP] -c checkcounter -a "Counter=\\Process(nscp)\Working Set"
OK: \Process(nscp)\Working Set = 22421504|'\Process(nscp)\Working Setnone'=22421504;0;0

However, I prefer the output in other size, KB, MB... How can I get it?

Thanks.

Unit conversions aren't supported by default, you would have to write a wrapper script on the XI server or write a script on the remote server that would handle the conversions.

I did the script but in nagiosgraph I see an error:

Code: Select all

No data available: host=hostname service=Check NSClien db=

Why? How can I fix it?

Could you post the script so we can review it?

When you changed your code did you per-chance change the service name? This looks like a misspelling of sorts otherwise:

No data available: host=hostname service=Check NSClien db=

Actually, truth be told, it doesn't even look related to the plugin you're munging.
