Monitor Cloud Exchange with Prometheus and Grafana - Netskope Technical Documentation

Configure a Metric Exporter for Cloud Exchange

Download the latest version of the linux node exporter from: Releases · prometheus/node_exporter.

$ wget https://github.com/prometheus/node_exporter/releases/download/v1.7.0/node_exporter-1.7.0.linux-amd64.tar.gz

Extract the node exporter and start it in the background.

$ tar -xvf node_exporter-1.7.0.linux-amd64.tar.gz
$ cd node_exporter-1.7.0.linux-amd64
$ ./node_exporter &

Verify the connectivity by opening your machine address with port 9100.
```
> http://<machine_IP>:9100
```

Note

If this is to be used for an EC2 instance, make sure you expose the port from AWS console > inbound rules.

Note

We recommend that you configure Prometheus and Grafana on a new instance so it will not affect existing Cloud Exchange performance.

You will need to install docker and docker-compose on the new machine, and then use the steps in the following sections to configure Prometheus and Grafana on the new machine.

Configure Prometheus

Create a prom directory in /opt.
```
$ cd /opt
$ mkdir prom
```

Create a Prometheus config file with the following content.

$ vi prom/prometheus.yml

Note

Change your machine IP in the targets section.

global:
  scrape_interval: 15s
  scrape_timeout: 10s
  evaluation_interval: 15s
alerting:
  alertmanagers:
  - follow_redirects: true
    enable_http2: true
    scheme: http
    timeout: 10s
    api_version: v2
    static_configs:
    - targets: []
scrape_configs:
- job_name: machines
  scrape_interval: 5s
  scrape_timeout: 5s
  scheme: http
  metrics_path: /metrics
  static_configs:
  - targets:
    - :9100

Create a docker-compose file with following content.

$ vi prom/docker-compose.yml

version: "3.3"
services:
  prometheus:
    image: prom/prometheus
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
    ports:
      - "9090:9090"

Start Prometheus.

$ cd prom
$ docker-compose up -d
$ cd ..

Verify the connectivity by going to: http://<your machine ip>:9090/

Configure Grafana

Create a grafana directory in /opt.
```
$ cd /opt
$ mkdir grafana
```

Create a docker-compose file with following content.

$ vi grafana/docker-compose.yml

version: "3.3"
services:
  grafana:
    user: "0"
    image: grafana/grafana-enterprise
    volumes:
      - ./data:/var/lib/grafana:z
    ports:
      - "3000:3000"

Start Grafana.

$ cd grafana
$ docker-compose up -d
$ cd ..

Open the Grafana UI by going to: http://<your machine ip>:3000/
1. Log in with default credentials admin / admin).
2. Change the default password.
Log in to Grafana with the new password.
Now add Prometheus as the Data Source.
1. Click the menu icon, expand Connections, and click Data sources.
2. Click Add data source.
3. Select Prometheus.
4. Enter the Prometheus settings, and then scroll down and click Save & test.
Create a Dashboard.
1. Go to the home page and click Create your first dashboard.
2. Click Import dashboard.
3. Enter 1860 for the ID and click Load.
4. Enter a Dashboard name, select the Prometheus data source that you added previously, and then click Import.
Now you can see the dashboard for a Cloud Exchange instance.
