Dashboards

In this page we see steps to setup dashboards for monitoring the clusters

Accessing Grafana Credentials:

First step is getting access to grafana servers at http://<server-ip>:30002. The username is admin. While the command below retrieves the admin password, which is stored as a Kubernetes secret in the default namespace:

kubectl get secret --namespace default grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo

Adding Prometheus as a Data Source:

Before to setup the dashboard, prometheus must be defined as a datasource for grafana

1. Access Grafana with web browser.
2. On the Grafana home page, click "Add your first data source".
3. From the list of available data sources, select Prometheus (under the "Time Series Databases" category).
4. In the HTTP URL field, enter the URL to Prometheus server http://<CLUSTER-IP>.

   kubectl get svc prometheus-server -o jsonpath='{.spec.clusterIP}'
   

   
5. Leave other settings as default unless you need specific configurations (e.g., authentication).
6. Scroll to the bottom of the page and click the "Save & Test" button. Grafana will confirm if the connection to Prometheus is successful.
7. Start Building Dashboards

Once the data source is added, you can use it to create panels and dashboards in Grafana.

Import a dashboard in Grafana:

1. Navigate: ☰ → Dashboards → New → Import
2. Upload: Select and upload the desired .json file.

json files with possible dashboards are available in ./grafana-dashboards .
