+Health latency history
+
+Returns the database healthcheck latency (ms) as three series, each oldest first with unix-ms timestamps. `raw` holds the per-minute samples of the last 3 hours; `avg` and `max` hold the 30-minute aggregates (over the last 4 hours of samples) kept for 30 days. Requires a valid JWT; no company selection needed.
