# Production Metrics

sglang exposes the following metrics via Prometheus. The metrics are namespaced by `$name` (the model name).

An example of the monitoring dashboard is available in [examples/monitoring/grafana.json](../examples/monitoring/grafana.json).

Here is an example of the metrics:

```

## Setup Guide

To setup a monitoring dashboard, you can use the following docker compose file: [examples/monitoring/docker-compose.yaml](../examples/monitoring/docker-compose.yaml).

Assume you have sglang server running at `localhost:30000`.

To start the monitoring dashboard (prometheus + grafana), cd to `examples/monitoring` and run:

```bash
docker compose -f compose.yaml -p monitoring up
```

Then you can access the Grafana dashboard at http://localhost:3000.

### Grafana Dashboard

To import the Grafana dashboard, click `+` -> `Import` -> `Upload JSON file` -> `Upload` and select [grafana.json](../examples/monitoring/grafana.json).
