Netdata Monitoring

Overview

Netdata is a real-time performance monitoring solution that provides comprehensive insights into the health and performance of systems and applications. This guide will cover how to set up Netdata monitoring within the HostSpace Kubernetes Engine (HKE), an enterprise-grade Kubernetes orchestration platform.

Key Features/Components

  • Real-time monitoring of system and application metrics
  • Visualizations for easy analysis
  • Alerts for proactive issue resolution
  • Extensible with custom plugins

Step-by-step Instructions or Configuration Details

  1. Deploy Netdata on Kubernetes: Use the following YAML manifest to deploy Netdata: 
    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: netdata
    spec:
      replicas: 1
      selector:
        matchLabels:
          app: netdata
      template:
        metadata:
          labels:
            app: netdata
        spec:
          containers:
          - name: netdata
            image: netdata/netdata
            ports:
            - containerPort: 19999
  2. Expose Netdata Service: Expose the Netdata service to access the dashboard:
    Terminal window
    kubectl expose deployment netdata --port=19999 --target-port=19999
  3. Access Netdata Dashboard: Access the Netdata dashboard using the exposed service.

Best Practices and Recommendations

  • Secure the Netdata dashboard with authentication mechanisms.
  • Regularly update Netdata to benefit from the latest features and security patches.
  • kubectl get pods - View running pods
  • kubectl describe pod <pod_name> - Get detailed information about a pod
  • Netdata API documentation for advanced integrations
