The recording level for all metrics will be INFO
...
Estimated memory in bytes used for reading SST tables, excluding memory used in block cache (e.g., filter and index blocks). This metric records the memory used by iterators as well as filters and indices if the filters and indices are not maintained in the block cache. Basically this metric reports the memory used outside the block cache to read data. For segmented state stores, the sum of the estimated memory over all segments is reported.
estimate-oldest-key-time
Estimated oldest key timestamp in the RocksDB instance. This metric is currently only available for FIFO compaction with compaction_options_fifo.allow_compaction = false. For segmented state stores, the minimum of the estimated oldest key timestamp over all segments is reported.
background-errors
Accumulated number of background errors. For segmented state stores, the sum of the number of background errors over all segments is reported.
