Monitoring dashboard for Kubernetes hosted node.

Monitoring a Kubernetes hosted node requires installing Grafana agent on your Kubernetes cluster and passing the agent.yaml as ConfigMap. Follow these steps to get your nodes monitored!

Before you begin

A Kubernetes cluster with role-based access control (RBAC) enabled.
Your node metrics endpoint need to be exposed via a service.
The kubectl command-line tool installed on your local machine, configured to connect to your cluster. To learn more about kubectl, see the Kubernetes documentation.
To install using Helm (best practice) verify Helm is running in your Kubernetes configuration. See https://github.com/kubernetes/helm for more information.
A Scale3 Autopilot tenant remote-write endpoint. You will need this to populate the values.yaml file. Get in touch here to have a tenant provisioned for you.

There are two supported methods of installation:

Deploy using Helm (Recommended)
Deploy using YAML (TBD)

Deploy using Helm

Helm, maintained by the CNCF, allows the Kubernetes administrator to install, upgrade, and manage the applications running in their Kubernetes clusters. For more information on how to use and configure Helm Charts, see the Helm site and repository for tutorials and product documentation.

To install and configure with Helm:

Add Grafana Agent chart repo

helm repo add grafana https://grafana.github.io/helm-charts
helm repo update

Create a values.yaml file with the tenant information provisioned as part of the prerequisites.

values.yaml example for ETH node

Example values.yaml file. Please copy and customize with your tenant specific information. Replace all values indicate by #REPLACE_ME with your tenant specific values.

# Various agent settings.
agent:
  # -- Mode to run Grafana Agent in. Can be "flow" or "static".
  mode: "static"
  configMap:
    # -- Create a new ConfigMap for the config file.
    create: true
    # -- Content to assign to the new ConfigMap. This is passed into `tpl` allowing for templating from values.

                max_samples_per_send: 500

                max_backoff: 15s
          external_labels:
            tenant_id: YOUR_TENANT_ID #REPLACE_ME
            hostname: ${HOSTNAME}
        configs:
          - name: "lighthouse_vc"
            scrape_configs:
              - job_name: "lighthouse_vc Metrics" 
                honor_timestamps: false
                static_configs:
                  - targets: ["localhost:5064"]
          - name: "lighthouse_bc"
            scrape_configs:
              - job_name: "lighthouse_bc Metrics" 
                honor_timestamps: false
                static_configs:
                  - targets: ["localhost:5054"]
          - name: "geth"
            scrape_configs:
              - job_name: "geth Metrics" 
                metrics_path: /debug/metrics/prometheus
                scheme: http
                honor_timestamps: false
                static_configs:
                  - targets: ["target"]

Once you’ve customized the values.yaml file with your tenant information. Install the chart with by running

helm install my-grafana-agent -f values.yaml grafana/grafana-agent

Navigate to your node monitoring dashboard within Scale3 Autopilot, you should see data from your node starting to populate.
