To setup a monitoring dashboard, you can use the following docker compose file: [examples/monitoring/docker-compose.yaml](../examples/monitoring/docker-compose.yaml). 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`. Assume you have sglang server running at `localhost:30000`, to start the server, ensure you have `--enable-metrics` flag enabled:
```bash
python -m sglang.launch_server --model-path meta-llama/Meta-Llama-3.1-8B-Instruct \
--port 30000 --host 0.0.0.0 --enable-metrics

### Grafana Dashboard ### Grafana Dashboard
In a new Grafana setup, ensure that you have the `Prometheus` data source enabled. To check that, go to `http://localhost:3000/connections/datasources` and ensure that `Prometheus` is enabled.
If not, click `Add data source` -> `Prometheus`, set Prometheus URL to `http://localhost:9090`, and click `Save & Test`.
To import the Grafana dashboard, click `+` -> `Import` -> `Upload JSON file` -> `Upload` and select [grafana.json](../examples/monitoring/grafana.json). To import the Grafana dashboard, click `+` -> `Import` -> `Upload JSON file` -> `Upload` and select [grafana.json](../examples/monitoring/grafana.json).
### Troubleshooting
#### Check if the variables are created
The example dashboard assume you have the following variables avaliable:
- `model_name` (name: `model_name`, label: `model name`, Data source: `Prometheus`, Type: `Label values`)
- `instance` (name: `instance`, label: `instance`, Data source: `Prometheus`, Type: `Label values`)
If you don't have these variables, you can create them manually.
To create a variable, go to dashboard settings, `Variables` -> `New variable`.
You should be able to see the preview the values (e.g. `meta-llama/Llama-3.1-8B-Instruct` for `model_name`).
#### Check if the metrics are being collected
Run `python3 -m sglang.bench_serving --backend sglang --dataset-name random --num-prompts 3000 --random-input 1024 --random-output 1024 --random-range-ratio 0.5` to generate some requests.
Then you should be able to see the metrics in the Grafana dashboard.
