TKE Serverless Cluster collects and displays metrics for clusters, workloads, pods, and containers.

Prerequisites

An TKE Serverless cluster has been created and is in the Running state. For more information, see Creating a Cluster.

Procedure

1. Log in to the TKE console and click Elastic Cluster in the left sidebar.
2. On the Cluster Management page that appears, click the ID of the TKE Serverless cluster.
3. On the cluster resource management page, view the metrics and configure alarms for them. For more information, see the following documents:

Setting Alarms

Monitoring and Alarm Metrics

Monitoring metrics

TKE currently provides monitoring metrics in the following dimensions. All metrics are average values of the statistics collected within the statistical period.
Note:
For monitoring metrics for persistent volumes (PVs) used by a workload, see Block Storage and Cloud File Storage.
For network monitoring metrics for a CLB associated with a Service, see the Cloud Load Balancer.
For more information on how to create an alarm policy, see Creating an Alarm Policy.
