Prometheus Metrics

Expose and scrape process-wide RivetKit metrics from a worker.

RivetKit exposes Prometheus metrics that help diagnose actor activity, networking, SQLite behavior, and more.

Mount registry.routes.prometheusMetrics() in your HTTP router. For example, with Hono: app.get("/metrics", (c) => registry.routes.prometheusMetrics(c.req.raw)).

Configure Prometheus to scrape the mounted path on every worker instance.

By default, this endpoint is exposed without authentication. If your metrics may contain private information, protect it with a token or expose it only on a private router or network.
