Hello,
What would you advice to assess the physical memory utilisations of processes and vservers ? The RSS column of ps, as well the vserver-stat does not take into account the shared memory, due for instance to CoW between processes inside the same vserver but also across vservers thanks to the unification.
I could stop/start services and vservers, and call "free" before and after, make the difference. But is there a way more practical and more precise ?
Is there a tool to get the map of the physical memory and how each page is used (mapped to a process virtual space, kernel, etc...), or a tool to compute the amount of shared memory between 2 (or more) processes ?
