Monitoring Azure Kubernetes Cluster
Azure Monitor for containers is a feature designed to monitor the performance of container workloads deployed to either Azure Container Instances or managed Kubernetes clusters hosted on Azure Kubernetes Service (AKS). Monitoring your containers is critical, especially when you’re running a production cluster, at scale, with multiple applications.
Azure Monitor for containers gives you performance visibility by collecting memory and processor metrics from controllers, nodes, and containers that are available in Kubernetes through the Metrics API. Container logs are also collected. After you enable monitoring from Kubernetes clusters, these metrics and logs are automatically collected for you through a containerized version of the Log Analytics agent for Linux and stored in your Log Analytics workspace.
Here you find awesome documentation about Understanding AKS cluster performance with Azure Monitor for containers
What I really like is that you now can see the Container Live logs from the Azure portal and see what is going on in the background of a Container 🙂
Activate Azure Kubernetes Container Live Logs
Here you see the Container Live logs
This feature provides a real-time view into your Azure Kubernetes Service (AKS) container logs (stdout/stderr) without having to run kubectl commands. When you select this option, new pane appears below the containers performance data table on the Containers view, and it shows live logging generated by the container engine to further assist in troubleshooting issues in real time.
Live logs supports three different methods to control access to the logs:
- AKS without Kubernetes RBAC authorization enabled
- AKS enabled with Kubernetes RBAC authorization
- AKS enabled with Azure Active Directory (AD) SAML based single-sign on
You even can search in the Container Live Logs for Troubleshooting and history :
Search on ssh
Azure Monitor for containers uses a containerized version of the Log Analytics agent for Linux. After initial deployment, there are routine or optional tasks you may need to perform during its lifecycle.
Because of this agent you can work with Log Analytics in Azure Monitor :

Conclusion :
When you have your production workload running on Azure Kubernetes Clusters, It’s important to monitor to keep you in Control of the solution in Microsoft Azure and watch for improvements like performance for the business. With Container Live logs you can see what is going on in the Containers when you have issues and that’s great for troubleshooting to get your problem solved fast. Get your workload into Azure Containers and make your Azure DevOps CI/CD Pipelines in the Cloud.
