RAM usage/Exclude from Widget

Hello there,

First of all, I thought I was facing an issue with the RAM used by my monitoring server.
Found some infos on LinuxAteMyRam and so now I think everything 's fine with it, though my problem looks different today.

I’m using Top Device Widget, to check memory usage on my servers.
The problem is that Linux servers are top devices and It doesn’t help me to check Windows server efficiently.

So the questions are:

  • Is there a way to have more accurate informations showing ram usage on Linux servers ?
  • If not, is there a way to exclude devices (or a group even) from a top device widget ?

By the way, I tried to disable memory polling per device in “modules”, but it was not a good idea since I lost RAM report AND the device still remained in Top Device, with no graph though.

Thanks for your help,
