Grafana Dashboard
-------
There are two dashboard to choose from:  
### The First
Grafana Dashboard ID: 10477, name: RocketMQ Exporter Overview.
For details of the dashboard please see [RocketMQ Exporter Overview](https://grafana.com/grafana/dashboards/10477-rocketmq-dashboard/).

SkyWalking Dashboard
-------

Since 10.0, SkyWalking has provided bundled native monitoring dashboards for RocketMQ through this exporter and OpenTelemetry collector.
For settings details, please read [RocketMQ monitoring doc](https://skywalking.apache.org/docs/main/next/en/setup/backend/backend-rocketmq-monitoring/).

### The Second
[rocketmq_exporter.json](./rocketmq_exporter.json)

**Note**: It must be configured with two additional labels(Env and Cluster), when configured on the prometheus, as shown bellow:
```yaml
  - job_name: 'rocketmq-exporter'
    static_configs:
    - targets: ['localhost:5557']
      labels:
        Env: 'develop'
        Cluster: 'local'
```
Quick Start
-------------
This [guide](./rocketmq_exporter_quickstart.md) will tell you how to build and run rocketmq exporter with Prometheus and Grafana Integration from scratch.
