AKS Node Health

By enabling this toolset, HolmesGPT will be able to perform specialized health checks and troubleshooting for Azure Kubernetes Service (AKS) nodes, including node-specific diagnostics and performance analysis.

Prerequisites

  1. Azure CLI installed and configured
  2. Appropriate Azure RBAC permissions for AKS clusters
  3. Access to the target AKS cluster
  4. Node-level access permissions

Configuration

First, ensure you're authenticated with Azure:

az login
az account set --subscription "<your subscription id>"

Then add the following to ~/.holmes/config.yaml, creating the file if it doesn't exist:

toolsets:
  aks/node-health:
    enabled: true
    config:
      subscription_id: "<your Azure subscription ID>"
      resource_group: "<your AKS resource group>"
      cluster_name: "<your AKS cluster name>"

holmes:
  toolsets:
    aks/node-health:
      enabled: true
      config:
        subscription_id: "<your Azure subscription ID>"
        resource_group: "<your AKS resource group>"
        cluster_name: "<your AKS cluster name>"

Advanced Configuration

You can configure additional health check parameters:

toolsets:
  aks/node-health:
    enabled: true
    config:
      subscription_id: "<your Azure subscription ID>"
      resource_group: "<your AKS resource group>"
      cluster_name: "<your AKS cluster name>"
      health_check_interval: 300  # Health check interval in seconds
      max_unhealthy_nodes: 3  # Maximum number of unhealthy nodes to report
