The MySQL MyRocks Metrics dashboard is missing
couple of crucial information.
I suggest to add equivalent of InnoDB Row Operations - "RocksDB Row Operations" graph, with series like:
Also, graph showing "Memtable Size", with for example:
mysql_global_status_rocksdb_memtable_total/1024/1024 as Memtable Total MB
mysql_global_status_rocksdb_memtable_unflushed/1024/1024 as Memtable Unflushed MB
Another graph IMHO worth adding: "RocksDB Stalls", including rate variables:
- mysql_global_status_rocksdb_stall_micros (this one may be very fast growing, not like the others, so should be probably scaled differently)
