Fixed In Version: gluster-nagios-addons-0.2.1-1.el6rhs.x86_64.rpm Doc Type: Bug Fix
Doc Text:
Previously, the Memory utilization plugin was not deducting cached memory from used memory. This caused Nagios to alert for a low memory condition when none actually exists. With this fix, the used value is obtained by deducting cached value from it. Now, the Memory utilization plugin will return the correct value for used memory and hence there will be no false low memory alerts.

Kevin,

      We will have to deduct both cached and buffered space from the used space to get the *actual* used space right ?

Please provide your inputs on this.

Comment 9 RamaKasturi 2015-05-29 08:52:34 UTC 
Verified and works fine with build gluster-nagios-addons-0.2.1-1.el6rhs.x86_64.rpm.

with this fix cached memory is also being deducted from the Used space to get the actual used space.
