Memory saved by KSM

demon007 · 03-07-2012, 03:01 AM

I am using madvise() in my program to mark the allocated memory as mergeable. In the KSM, I can see that pages are getting merged.

My problem is that I am not able to monitor the actual memory being saved from the top command.

Is there a way to monitor the memory saved by using KSM and the overheads of using KSM.

Please help me. I really need it.

Thank you in advance.

Why you can't use top?
You can see RES and SHR fields and also can check cpu load of ksmd worker thread there.
