Queries the monitoring data on a time series metric of a cloud service in a specified period.

For more information about how to assign values to the Namespace, Project, Metric, Period, and Dimensions parameters for cloud services, see DescribeMetricMetaList or Appendix 1: Metrics.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes DescribeMetricList

The operation that you want to perform. Set the value to DescribeMetricList.

MetricName String Yes cpu_idle

The name of the metric.

Namespace String Yes acs_ecs_dashboard

The namespace of the service.

Specify the value in the format of acs_Service name.

Period String No 60

The time interval at which monitoring data is queried. Unit: seconds. Valid values: 60, 300, and 900.

Set this parameter as needed.

StartTime String No 2019-01-30 00:00:00

The beginning of the time range to query. Supported formats:

  • UNIX timestamp: the number of milliseconds that have elapsed since the epoch time January 1, 1970, 00:00:00 UTC.
  • Time format: YYYY-MM-DDThh:mm:ssZ.
Note The period specified by StartTime and EndTime includes the time point specified by EndTime but does not include the time point specified by StartTime. StartTime must be earlier than EndTime.
EndTime String No 2019-01-30 00:10:00

The end of the time range to query. Supported formats:

  • UNIX timestamp: the number of milliseconds that have elapsed since the epoch time January 1, 1970, 00:00:00 UTC.
  • Time format: YYYY-MM-DDThh:mm:ssZ.
Dimensions String No [{"instanceId": "i-abcdefgh12****"}]

The dimensions that specify the resources for which you want to query alert rules.

Set the value to a collection of key-value pairs. A typical key-value pair is instanceId:XXXXXX.

The key and value must be 1 to 64 bytes in length, respectively. Excessive bytes are truncated from the string.

The key and value can contain letters, digits, periods (.), hyphens (-), underscores (_), forward slashes (/), and backslashes (\).

Note Dimensions must be organized in a JSON string and follow the required order.
NextToken String No 15761485350009dd70bb64cff1f0fff750b08ffff073be5fb1e785e2b020f1a949d5ea14aea7fed82f01dd8****

The pagination cursor.

Note If this parameter is not specified, the data on the first page is returned. The returned value indicates that not all entries have been returned. You can use this value as an input parameter to obtain entries on the next page. If a response is empty, all query results have been returned.
Length String No 1000

The number of entries to return on each page.

Express String No {"groupby":["userId","instanceId"]}

The expression for real-time computation on the query results.

Only the groupby expression is supported, which is similar to the GROUP BY statement used in databases.

Response parameters

Parameter Type Example Description
RequestId String 3121AE7D-4AFF-4C25-8F1D-C8226EBB1F42

The ID of the request.

Code String 200

The HTTP status code.

Note The status code 200 indicates that the call was successful.
Success Boolean true

Indicates whether the call was successful. The value true indicates a success. The value false indicates a failure.

NextToken String 15761441850009dd70bb64cff1f0fff6d0b08ffff073be5fb1e785e2b020f7fed9b5e137bd810a6d6cff5ae****

The pagination cursor.

Note If this parameter is not specified, the data on the first page is returned. The returned value indicates that not all entries have been returned. You can use this value as an input parameter to obtain entries on the next page. If a response is empty, all query results have been returned.
Period String 60

The time interval at which monitoring data was queried. Unit: seconds. Valid values: 60, 300, and 900.

Datapoints String [{"timestamp":1548777660000,"userId":"123","instanceId":"i-abc","Minimum":9.92,"Average":9.92,"Maximum":9.92}]

The obtained monitoring data of the metric.

Message String The Request is not authorization.

The returned message.
