+
+Health checks verify that a worker is healthy, including its connection to the Rivet control plane.
+
+Mount `registry.routes.health()` in your HTTP router. For example, with Hono: `app.get("/health", () => registry.routes.health())`.
+
+A healthy worker returns `200` with its status, runtime, and version. If its connection to the control plane is unhealthy, it returns `503`. Point your liveness and readiness probes at the mounted path.

+description: "Expose RivetKit runtime metadata from a worker."
+---
+
+Exposing worker metadata is optional, but useful for verifying the RivetKit version and actor types running on a worker.
+
+Mount `registry.routes.metadata()` in your HTTP router. For example, with Hono: `app.get("/metadata", () => registry.routes.metadata())`.
+
+The endpoint returns the worker's runtime version, registered actor names, and connection metadata as JSON.

 - **Ensure log level is not set to debug.** Leave `RIVET_LOG_LEVEL` at its default or explicitly set it to `warn` to avoid excessive logging.
 - **Do not set `RIVET_EXPOSE_ERRORS=1` in production.** This exposes internal error details to clients. It is automatically enabled when `NODE_ENV=development`.

+- **Configure health probes.** Mount `registry.routes.health()` and verify your liveness and readiness probes receive `200`. See <SelfHostLink to="workers/health-checks">Health Checks</SelfHostLink>.
+- **Scrape Prometheus metrics.** This is recommended for monitoring worker performance and failures. See <SelfHostLink to="workers/prometheus-metrics">Prometheus Metrics</SelfHostLink>.

 ## Runtime Mode
 
 - **Configure a runner version.** Required for graceful upgrades and draining of old actors. Applies to both serverless and runner modes.

+title: "Prometheus Metrics"
+description: "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.
