RPC Usage
Last updated
Last updated
Fetch RPC reverse-proxy usage analytics — request volume, latency p50/p95, failover + error rate, cache-hit rate, per-endpoint distribution, and bounded time buckets for heatmaps — over a 7d or 30d window (computed live from the store telemetry).
Trailing lookback window the response is computed over, ending at the most recent data point rather than at today. Accepts 7d, 30d. A longer window is not a superset of a shorter one -- rankings and rates are recomputed over the whole window, not summed.
