summary

MariaDB exposes concrete observability: Performance Schema with ~80 tables, almost 1,000 instrumentation points (≈300 time-instrumented) and picosecond timings; Information Schema tables like innodb_metrics and innodb_mutexes for min/max counters and mutex contention; SHOW STATUS and extended processlist with microsecond resolution; error, general and slow logs that can include EXPLAIN and ANALYZE output for actual row counts; Percona Monitoring and Management is offered as an open source visualization and query‑optimization tool.
