# Monitoring

> Health checks, metrics, logs, and tracing

Use this page after the node starts cleanly. It covers the endpoints and telemetry knobs you can wire into probes and observability.

## Health

```bash theme={null}
curl http://localhost:8000/healthz
```

Use `/healthz` for load balancers, container probes, and uptime checks.

## Metrics

Enable the Prometheus server with telemetry and use the metrics port for scraping.

```toml theme={null}
[telemetry]
enabled = true

[prometheus]
port = 8001
```

## Logging

```toml theme={null}
[log]
format = "Text"
```

Switch to `Json` when you want structured logs for a collector or log shipper.

## Tracing

Enable tracing under `[log.tracing]`. The current node builds its OTLP gRPC
exporter with the library's default collector endpoint; TinyCloud config does
not currently expose an endpoint override.

```toml theme={null}
[log.tracing]
enabled = true
```

The node exports OTLP spans; your collector can forward them to whatever
backend you use when it is reachable at that endpoint.

## What to avoid

* Do not expose the metrics port publicly
* Do not rely on tracing being on by default
* Do not assume the Prometheus server starts unless telemetry is enabled

<Note>
  The node's tracing code uses OpenTelemetry OTLP export. The docs here stay at that level instead of naming a specific collector backend.
