There was a problem hiding this comment.
In the documentation, each section is enabled/disabled separately. If you introduce instance section, its metrics should be in a separate section.

It seems that box.info.memory().cache and box.stat.vinyl().tuple_cache are the same, so they're counted twice
cache– the 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.
(https://www.tarantool.io/en/doc/latest/reference/reference_lua/box_info/memory/)
The same goes for box.info.memory().data and box.info.memory().index
data– the 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.
index– the number of bytes used for indexing user data, including memtx and vinyl memory tree extents, the vinyl page index, and the vinyl bloom filters.
