TKE provides users with an out-of-the-box audit dashboard and can automatically configure dashboards of auditing overview, node operation overview, K8s object operation overview, and aggregation search for the clusters with the feature of Cluster Auditing enabled. With user-defined filter items, and built-in CLS global search, TKE makes it convenient for users to observe and search various cluster operations, so as to find and locate problems in time.

Node operation overview

When you need to troubleshoot node problems, you can set filters on the Node operation overview page to view dashboards of various node operations, including create, delete, patch, update, block, and evict.

K8s object operation overview

When you need to troubleshoot problems related to K8s objects (such as a certain workload), you can go to the K8s object operation overview page, and set filter conditions to view the details of the operation overview, the corresponding users, and the corresponding audit log list of various K8s objects.

Aggregation search

When you want to view the distribution trend of audit logs in a certain dimension, you can set filter conditions on the "Aggregation search" page to view the sequence diagrams of various important operations. The dimensions include the user, namespace, operation type, status code, resource type, and the corresponding audit log list.

Global search

Global search dashboard, with built-in CLS search analysis page, is convenient for users to quickly search all audit logs in the TKE console.
