memory.stat file includes following statistics
memory.stat file includes following statistics:
per-memory cgroup local status
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* per-memory cgroup local status
=============== ===============================================================
cache # of bytes of page cache memory.
rss # of bytes of anonymous and swap cache memory (includes
transparent hugepages).
rss_huge # of bytes of anonymous transparent hugepages.
mapped_file # of bytes of mapped file (includes tmpfs/shmem)
pgpgin # 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 # of uncharging events to the memory cgroup. The uncharging
event happens each time a page is unaccounted from the cgroup.
swap # of bytes of swap usage
dirty # of bytes that are waiting to get written back to the disk.
writeback # of bytes of file/anon cache that are queued for syncing to
disk.
inactive_anon # of bytes of anonymous and swap cache memory on inactive
LRU list.
active_anon # of bytes of anonymous and swap cache memory on active
LRU list.
inactive_file # of bytes of file-backed memory and MADV_FREE anonymous memory(
LazyFree pages) on inactive LRU list.
active_file # of bytes of file-backed memory on active LRU list.
unevictable # of bytes of memory that cannot be reclaimed (mlocked etc).

hierarchical_memsw_limit # of bytes of memory+swap limit with regard to
hierarchy under which memory cgroup is.
