Hello,

I'm using the built-in memory check command for linux ($USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c check_mem -a '-w 20 -c 10') and I'm getting the following service response: WARNING - 1378 / 1877 MB (%) Free Memory, Used: 499 MB, Shared: 0 MB, Buffers: 70 MB, Cached: 237 MB

My linux knowledge is not the best, however I don't think I should be seeing a warning here. If I'm reading this correctly it looks like I have 73% free memory, which shouldn't cause a warning.

I'm running CentOS 6.3

Thanks for any help you can give me.

Run on the client machine:

Code: Select all

yum install dc -y

or

Code: Select all

sudo apt-get install dc

depending on the distro.

Hope this helps.

When running the yum command I get:

Awesome! Now I'm seeing
OK - 1375 / 1877 MB (73%) Free Memory, Used: 502 MB, Shared: 0 MB, Buffers: 71 MB, Cached: 239 MB

Thanks so much!
