(Optional) Step 4: Install Prometheus Node Exporter

The following example shows how to create a Grafana dashboard based on a Grafana template. The Grafana template is used with Prometheus Node Exporter to monitor a node in an Elastic Compute Service (ECS) instance.

Download Prometheus Node Exporter.
- Download Prometheus Node Exporter from the official website of Prometheus .
- Download Prometheus Node Exporter by running the following command.
```
wget https://github.com/prometheus/node_exporter/releases/download/v1.2.0/node_exporter-1.2.0.linux-amd64.tar.gz
```
Check the connectivity of Prometheus Node Exporter.
Start Prometheus Node Exporter and run the following command:
```
curl http://localhost:9100/metrics
```
Note
- Replace the localhost and port in the command based on your business requirements.
- We recommend that you try to access http:// [ECS IP]:9100/metrics from other ECS instances to check whether the network connectivity is blocked by a security group rule.
Add the IP address of Prometheus Node Exporter for service discovery.
- Managed Service for Prometheus:
  1. Log on to the Application Real-Time Monitoring Service (ARMS) console. In the left-side navigation pane, choose Managed Service for Prometheus > Instances.
  2. In the top navigation bar, select the region in which the Managed Service for Prometheus instance resides. In the Instances section, click the name of the instance that you want to manage.
  3. On the instance details page, click Settings in the left-side navigation pane. On the Settings tab, click Edit Prometheus.yaml to add the IP address of Prometheus Node Exporter that is specified in the preceding command.
- Self-managed Prometheus instance:
  Add the IP address of Prometheus Node Exporter to the Prometheus.yml file.
```
scrape_configs:
    - job_name: 'prometheus'
      static_configs:
      - targets: ['[Node Exporter IP]:9100']
```
