Collect the logs of control plane components in a managed Kubernetes cluster

Enable log collection for control plane components

When you create a cluster, select Enable for Log Collection for Control Plane Components on the Component Configurations wizard page. For more information, see Create a managed Kubernetes cluster or Create a professional managed Kubernetes cluster.

Note

• By default, Enable is selected when you create a professional managed Kubernetes cluster. By default, this check box is unselected when you create a standard managed Kubernetes cluster.
• You can select an existing Log Service project in the Log Collection for Control Plane Components section.

View the logs of control plane components

After you create the managed Kubernetes cluster, you can view the logs of the control plane components by using one of the following methods:

Method 1: View the logs of control plane components in the Log Service console.

1. Log on to the Log Service console.
2. In the Projects section, click the name of the Log Service project that is used for the cluster.
3. On the Log Storage page, click the Logstores tab on the left side of the page and click the Logstore where the logs of control plane components are stored. You can query the logs of the following components: kube-apiserver, kube-scheduler, and kube-controller-manager. For more information, see Overview of Log Service.

Method 2: View the logs of control plane components in the ACK console.

1. Log on to the ACK console.
2. In the left-side navigation pane, click Clusters.
3. On the Clusters page, find the cluster that you want to manage and click the name of the cluster or click Details in the Actions column. The details page of the cluster appears.
4. View the three control plane components.
   • You can view the three control plane components through the Cluster Information menu.
     1. On the cluster details page, click the Cluster Resources tab and click the URL of the Log Service project.
     2. On the Log Storage page, click the Logstores tab on the left side of the page and click the Logstore where the logs of control plane components are stored. You can query the logs of the following components: kube-apiserver, kube-scheduler, and kube-controller-manager. For more information, see Overview of Log Service.
   • You can also view the three control plane components through the Operations menu.
     1. In the left-side navigation pane of the cluster details page, choose Operations > Log Center.
     2. Click the Logs of Control Plane Components tab. You can select a component and view its logs.

Logstores for control plane components

ACK allows you to collect the logs of the following control plane components. The logs of each component are stored in a separate Logstore. For more information about the components, see Kubernetes components.
