machine agent not reporting memory utilization correctly

Hi all,

We have a machine agent installed on a linux and it is reporting to controller but when when we check the memory utilization statics is show showing a lower value than what we get when we run top command on the linux box in our case memory utiliztion in AppD is 1.8GB but top command on the machine is showing 12GB. Can you please let how to fix this issue.

Thanks,

Hari
