Reported RAM usage is wrong?

x-cimo
In the dashboard. I have 35% of 1.5 GB use. But if I ssh into ASG and run top, I have a totally different picture. Top report 1283 MB is use with 249Mb free.

Who's lying? [:S]

    Sounds about right, but keep in mind that nightly processes such as accounting, and up2dates, may make it higher at times.

    used    - buffers - cached:

    1270408 - 250056  - 545468 = 474884

    (so, around 30% of total memory)

    These 30% are the amount of RAM it really needs. Buffers and cached stuff is only used if there is free space in the RAM.

    A Linux system will always try to fill up your memory as much as possible for a better performance.

    On our 425 for example, we have 3GB: 

    used:    3244916k

    buffers: 186680k

    cached:  2462260k


    So, if the Astaro would show the amount of memory it uses including buffers and cached, it would be always be between 80 and ~97%.

    And that would be confusing for users too, because specially the cached stuff is only used because there was free memory left.
