Service Performance Dashboard Documentation

Overview​

The Service Performance Dashboard provides insights into the resource usage of Kubernetes pods, including memory and CPU utilization. It is designed to help operators monitor and optimize resource allocation by visualizing key metrics.

Panels Overview​

1. Memory Usage​

Memory Usage as % of Pod Memory Requests (All Pods)​

  • Description: Displays memory usage as a percentage of the total memory requested by each pod in the specified namespace.
  • Metrics Used:
    • Memory Usage: node_namespace_pod_container:container_memory_working_set_bytes
    • Memory Requests: cluster:namespace:pod_memory:active:kube_pod_container_resource_requests
  • Thresholds:
    • Green: Healthy (value < 80%)
    • Red: Critical (value ≥ 80%)

Memory Usage as % of Pod Memory Requests (Specific Pod)​

  • Description: Displays memory usage as a percentage of the total memory requested by a specific pod.
  • Metrics Used:
    • Memory Usage: node_namespace_pod_container:container_memory_working_set_bytes
    • Memory Requests: cluster:namespace:pod_memory:active:kube_pod_container_resource_requests
  • Thresholds:
    • Green: Healthy (value < 80%)
    • Red: Critical (value ≥ 80%)

2. CPU Usage​

CPU Usage as % of Pod CPU Requests (All Pods)​

  • Description: Displays CPU usage as a percentage of the total CPU requested by each pod in the specified namespace.
  • Metrics Used:
    • CPU Usage: node_namespace_pod_container:container_cpu_usage_seconds_total:sum_irate
    • CPU Requests: cluster:namespace:pod_cpu:active:kube_pod_container_resource_requests
  • Thresholds:
    • Green: Healthy (value < 80%)
    • Red: Critical (value ≥ 80%)

CPU Usage as % of Pod CPU Requests (Specific Pod)​

  • Description: Displays CPU usage as a percentage of the total CPU requested by a specific pod.
  • Metrics Used:
    • CPU Usage: node_namespace_pod_container:container_cpu_usage_seconds_total:sum_irate
    • CPU Requests: cluster:namespace:pod_cpu:active:kube_pod_container_resource_requests
  • Thresholds:
    • Green: Healthy (value < 80%)
    • Red: Critical (value ≥ 80%)

Setting Up the Dashboard​

To set up the Service Performance Dashboard, you need to manually import the dashboard JSON file into Azure Managed Grafana.

  1. Click the import button on the right-hand side.

    import button

  2. Click import JSON.

    import json

  3. Choose the service-performance-dashboard.json file from the docs/observability directory.

Once imported, you can start monitoring the resource usage of your system using the panels described above.

Conclusion​

The Service Performance Dashboard provides a centralized view of in-cluster resource utilization, enabling proactive monitoring and optimization. Each panel is tailored to highlight specific metrics and thresholds, ensuring that operators can quickly identify and address potential inefficiencies.
