	box.info.memory()
	The memory function of ``box.info`` gives the ``admin`` user a picture of the whole Tarantool instance.
	To get a picture of the vinyl subsystem, use :ref:`box.stat.vinyl() <box_introspection-box_stat_vinyl>` instead.
	memory().cache -- number of bytes used for caching user data. The memtx storage engine does not require a cache, so in fact this is the number of bytes in the cache for the tuples stored for the vinyl storage engine.
	memory().data -- number of bytes used for storing user data (the tuples) with the memtx engine and with level 0 of the vinyl engine, without taking memory fragmentation into account.
	memory().index -- number of bytes used for indexing user data, including memtx and vinyl memory tree extents, the vinyl page index, and the vinyl bloom filters.
	memory().lua -- number of bytes used for Lua runtime.
	memory().net -- number of bytes used for network input/output buffers.
	memory().tx -- number of bytes in use by active transactions. For the vinyl storage engine, this is the total size of all allocated objects (struct ``txv``, struct ``vy_tx``, struct ``vy_read_interval``) and tuples pinned for those objects.
	An example with a minimum allocation while only the memtx storage engine is in use:
	tarantool> box.info.memory() --- - cache: 0 data: 6552 tx: 0 lua: 1315567 net: 98304 index: 1196032 ...
