# Monitor private probes

The Synthetic Monitoring Agent exposes metrics that you can collect with Prometheus or Grafana Alloy to monitor a private probe. For help with an agent that isn’t working as expected, refer to [Troubleshoot private probes](/docs/grafana-cloud/observe-and-act/testing/synthetic-monitoring/set-up/set-up-private-probes/troubleshoot/).

## Production deployments

The agent process exposes Prometheus-style metrics on an HTTP server running on port 4050 with the “/metrics” endpoint.

You can scrape and monitor your private probe using Prometheus or [Grafana Alloy](https://github.com/grafana/alloy).
