# Talos Monitoring Features

Talos exposes Prometheus metrics, OpenTelemetry tracing, and health endpoints.

- [Prometheus metrics](/content/docs/talos/operate/monitoring/metrics/index.html) — request counts, latencies, and pool sizes
- [OpenTelemetry tracing](/content/docs/talos/operate/monitoring/tracing/index.html) — distributed request traces
- [Health checks](/content/docs/talos/operate/monitoring/health-checks/index.html) — liveness and readiness probes

## Edition differences

Both editions record business-logic metrics in-process: counters for keys created, verified, revoked, and rotated, plus cache hit and miss counters. The editions differ in what they expose and which signals they collect:

| Feature | OSS | Commercial |
| --- | --- | --- |
| In-process metric collection | Yes | Yes |
| `/metrics` scrape endpoint (port 4422) | No | Yes |
| `/health/alive` and `/health/ready` (main port 4420) | Yes | Yes |
| `/health/alive` and `/health/ready` (metrics port 4422) | Yes | Yes |
| OpenTelemetry trace export (`otlp` exporter) | No | Yes |

The OSS edition doesn't register a `/metrics` route or export traces. To scrape metrics or ship traces to a collector, use the commercial edition. Health endpoints work in both editions on both ports.
