Monitoring

API Version

The monitoring API version is bumped to v1alpha3.

Time format

The time format for query parameters must be in Unix timestamp, which is the number of seconds that has elapsed since the Unix epoch. Decimal is no longer allowed. The change affects the parameters start, end and time.

Response Fields

In KubeSphere 3.0.0, the response fields metrics_level, status and errorType are removed.

In addition, the field name resource_name has been replaced with the specific resource type names. These types are node, workspace, namespace, workload, pod, container and persistentvolumeclaim. For example, instead of resource_name: node1, you will get node: node1. See the example response below:
