nrpe check_mem

[sal@coned]

using: Nagios XI 2011R3.2

I have added a Ubuntu 12.04 server to be monitored and the NRPE check_mem is not behaving properly.
I have the service configured to be applied to a host-group and I'm getting different results depending on the version of Ubuntu.

The older Ubuntu release sends back the correct string, I have tried it with both with and without the % sign.

Any ideas ?

Thanks
Sal

This guest is the older Ubuntu and works as expected:
./check_nrpe -H cdais -t 30 -c check_mem -a '-w 20 -c 10'
OK - 1566 / 3024 MB (51%) Free Memory, Used: 1458 MB, Shared: 0 MB, Buffers: 210 MB, Cached: 1173 MB | total=3024MB free=1566MB used=1458MB shared=0 buffers=210MB cached=1173MB
./check_nrpe -H cdais -t 30 -c check_mem -a '-w 20% -c 10%

This is the Ubuntu 12.04 and it does not return the % used
./check_nrpe -H mrtg-dr-1 -t 30 -c check_mem -a '-w 20 -c 10'

You will get this if the dc package is not installed

Try running this on the 12.04 machine

Code: Select all

apt-get install dc

That worked.
