Querying Time Series Objects

Function

This API is used to query the time series objects that can be monitored in the system. You can specify a namespace, name, dimension, and resource ID (format: resType_resId). You can also specify the start position and the maximum number of returned records for a pagination query.

Calling Method

For details, see Calling APIs.

Example Requests

Query time series objects by namespace and metric_name.

https://{Endpoint}/v2/{project_id}/series

{
  "series" : [ {
    "namespace" : "PAAS.CONTAINER",
    "metric_name" : "aom_process_cpu_usage"
  } ]
}

Example Responses

Status code: 200

OK: The request is successful.

{
  "meta_data" : {
    "count" : 1,
    "offset" : null,
    "total" : 1,
    "nextToken" : 0
  },
  "series" : [ {
