Hello, I am trying to get the VSZ of the pids of a cgroup and its descendants, but I am not finding which is the best way to achieve this in any of the interfaces of cgroups. In kernel code I can see how memory.current includes anon and pagecache (file), and memory.swap.current includes all the swap. I also see how pages accounted in memory.current are discharged when they are charged to memory.swap.current. Also, I tested with a simple program which just does a malloc uses VSZ. I get the value from /proc, but I see no way to get this value in cgroups (e.g. from memory.stat fields). Does cgroups account for virtual memory? Is it too expensive to account for it? I cannot find it by reading the kernel but I might be wrong. Thanks Pd. I don't know where to ask it, so please forward me to the correct mailing list/source if this is not the one.
