5.2 stat file
-------------
-memory.stat file includes following statistics
-
-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).
-=============== ===============================================================
-
-status considering hierarchy (see memory.use_hierarchy settings)
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-========================= ===================================================
-hierarchical_memory_limit # of bytes of memory limit with regard to hierarchy
- under which the memory cgroup is
-hierarchical_memsw_limit # of bytes of memory+swap limit with regard to
- hierarchy under which memory cgroup is.
-
-total_<counter> # hierarchical version of <counter>, which in
- addition to the cgroup's own value includes the
- sum of all hierarchical children's values of
- <counter>, i.e. total_cache
-========================= ===================================================

-The following additional stats are dependent on CONFIG_DEBUG_VM
