[one-users] Host information

[Tino Vazquez]

Hi Ranga,

The free memory is calculated with the following line:

$ free -k|grep "buffers\/cache"|awk '{print $4}'

As you can see, this will get the 854328 figure out of the free output
provided, similar to the 853588 shown in the output.

This value is the free memory counting the cached pages that can be flushed.

Regards,

-Tino
