Key Default Description
state.backend.rocksdb.metrics.actual-delayed-write-rate
false Monitor the current actual delayed write rate. 0 means no delay.
state.backend.rocksdb.metrics.background-errors
false Monitor the number of background errors in RocksDB.
state.backend.rocksdb.metrics.compaction-pending
false Track pending compactions in RocksDB. Returns 1 if a compaction is pending, 0 otherwise.
state.backend.rocksdb.metrics.cur-size-active-mem-table
false Monitor the approximate size of the active memtable in bytes.
state.backend.rocksdb.metrics.cur-size-all-mem-tables
false Monitor the approximate size of the active and unflushed immutable memtables in bytes.
state.backend.rocksdb.metrics.estimate-live-data-size
false Estimate of the amount of live data in bytes.
state.backend.rocksdb.metrics.estimate-num-keys
false Estimate the number of keys in RocksDB.
state.backend.rocksdb.metrics.estimate-pending-compaction-bytes
false Estimated total number of bytes compaction needs to rewrite to get all levels down to under target size. Not valid for other compactions than level-based.
state.backend.rocksdb.metrics.estimate-table-readers-mem
false Estimate the memory used for reading SST tables, excluding memory used in block cache (e.g.,filter and index blocks) in bytes.
state.backend.rocksdb.metrics.mem-table-flush-pending
false Monitor the number of pending memtable flushes in RocksDB.
state.backend.rocksdb.metrics.num-deletes-active-mem-table
false Monitor the total number of delete entries in the active memtable.
state.backend.rocksdb.metrics.num-deletes-imm-mem-tables
false Monitor the total number of delete entries in the unflushed immutable memtables.
state.backend.rocksdb.metrics.num-entries-active-mem-table
false Monitor the total number of entries in the active memtable.
state.backend.rocksdb.metrics.num-entries-imm-mem-tables
false Monitor the total number of entries in the unflushed immutable memtables.
state.backend.rocksdb.metrics.num-immutable-mem-table
false Monitor the number of immutable memtables in RocksDB.
state.backend.rocksdb.metrics.num-live-versions
false Monitor number of live versions. Version is an internal data structure. See RocksDB file version_set.h for details. More live versions often mean more SST files are held from being deleted, by iterators or unfinished compactions.
state.backend.rocksdb.metrics.num-running-compactions
false Monitor the number of currently running compactions.
state.backend.rocksdb.metrics.num-running-flushes
false Monitor the number of currently running flushes.
state.backend.rocksdb.metrics.num-snapshots
false Monitor the number of unreleased snapshots of the database.
state.backend.rocksdb.metrics.size-all-mem-tables
false Monitor the approximate size of the active, unflushed immutable, and pinned immutable memtables in bytes.
state.backend.rocksdb.metrics.total-sst-files-size
false Monitor the total size (bytes) of all SST files.WARNING: may slow down online queries if there are too many files.
