In Azure Kubernetes Service (AKS), logging is a crucial aspect of monitoring and troubleshooting your applications. Azure Monitor Logs provides a powerful solution for collecting, analyzing, and visualizing log data from your AKS clusters. This tutorial will guide you through the process of setting up and utilizing Azure Monitor Logs for effective logging in AKS.
Prerequisites
Before getting started, ensure you have the following prerequisites:
- An Azure subscription
- An AKS cluster deployed
- Azure CLI installed
Step 1: Enable Azure Monitor Logs
To enable Azure Monitor Logs for your AKS cluster, execute the following Azure CLI command:
az aks enable-addons --addons monitoring --resource-group --name
Step 2: Configure Log Analytics Workspace
Next, you need to configure a Log Analytics Workspace to store the log data. Follow these steps:
- Create a new Log Analytics Workspace using the Azure portal or Azure CLI.
- Associate the Log Analytics Workspace with your AKS cluster using the following Azure CLI command:
az aks update -g -n --workspace-resource-id
Step 3: View and Query Logs
Once you have enabled Azure Monitor Logs and configured the Log Analytics Workspace, you can start viewing and querying logs.
For example, to retrieve the logs for a specific AKS node, use the following Azure CLI command:
az monitor log-analytics workspace query -g --workspace-name --analytics-query "ContainerLog | where TimeGenerated > ago(1d) | where Computer contains ''"
Common Mistakes to Avoid
- Forgetting to enable Azure Monitor Logs for your AKS cluster.
- Not configuring a Log Analytics Workspace or associating it with the AKS cluster.
- Using incorrect query syntax when retrieving logs.
