Free Memory Details

[Senthil_15]

I need to determine the total free memory available in the server . Will the output of kmeminfo and swapinfo will provide me the required info..??

Hi Senthil

Try with vmstat.

greetings

vmstat and glance -m will give you required details. kmeminfo gives infomation about kernel memeory. swapinfo is about swap space details.

man vmstat for details.

Hi,

Thanks for your information but we are not running GLANCE in our server . What will
be the alternate..??

vmstat
Look for free column. The values is in pages. Eah page is 4096bytes.

Also, you can 30 days evaluation copy of Glance.

Hi,

Thanks again for your info.

Does the "free" column in vmstat output will
include total free memory available for both Physical and Virtual (swap ) as well.( both inclusive )

RAC,

Thank You very much.

Senthil, also you can always use sam to check on memory.
Performance monitors ---> system properties ---> memory.

Hope that helps,

Jaime.
