Per-memory cgroup local status

Fields

cache: usize

of bytes of page cache memory.

rss: usize

of bytes of anonymous and swap cache memory (includes transparent hugepages).

rss_huge: usize

of bytes of anonymous transparent hugepages.

mapped_file: usize

of bytes of mapped file (includes tmpfs/shmem)

pgpgin: usize

of charging events to the memory cgroup. The charging event happens each time a page is accounted as either mapped anon page(RSS) or cache page(Page Cache) to the cgroup.

pgpgout: usize

of uncharging events to the memory cgroup. The uncharging event happens each time a page is unaccounted from the cgroup.

swap: usize

of bytes of swap usage

dirty: usize

of bytes that are waiting to get written back to the disk.

writeback: usize

of bytes of file/anon cache that are queued for syncing to disk.

inactive_anon: usize

of bytes of anonymous and swap cache memory on inactive LRU list.

active_anon: usize

of bytes of anonymous and swap cache memory on active LRU list.

inactive_file: usize

of bytes of file-backed memory on inactive LRU list.

active_file: usize

of bytes of file-backed memory on active LRU list.

unevictable: usize

of bytes of memory that cannot be reclaimed (mlocked etc).
