Scenario

Host Metrics - DimensionThis secHost Metricstion describes how to query time series objects about a node's CPU usage.

Obtaining Basic Information

Before querying time series objects, obtain the value of the node ID from dimensions on the ECS console, and the value of the cluster ID from dimensions on the cluster management page of the CCE console.

For metric_name of CPU usage, see Host Metrics. For the name corresponding to the cluster ID or node ID, see Host Metrics - Dimension. For the namespace, see Table 4 QuerySeriesOptionParam.

Querying Time Series Objects

URI format
POST /v2/{project_id}/series

Example request

POST https://{aom_endpoint}/v2/{project_id}/series

To obtain the value of {aom_endpoint}, see Regions and Endpoints..
