Health dashboards

Per-engine live metrics: pg_stat_*, MySQL processlist, Redis SLOWLOG, Mongo currentOp, SQLite PRAGMA. Pause / resume. Magellan attach.

Every database engine surfaces a Health tab with engine-specific metrics:

EngineReads
Postgrespg_stat_database / pg_stat_activity / pg_stat_replication + cache-hit % + dead-tuple bloat
MySQLSHOW PROCESSLIST + SHOW GLOBAL STATUS
RedisINFO sections + SLOWLOG
MongoDBserverStatus + currentOp
SQLitePRAGMAs + per-table row counts

Refresh

Refresh interval is user-controlled with pause / resume.

Magellan integration

The Health panel’s Magellan button sends the engine’s HealthSnapshot — sections, metrics, tone hints, slow-query tables — as context. See Magellan over DB Health.
