Cursor-阿里云帮助中心

Operation description

Before you begin

Make sure that Hybrid Cloud Monitoring is activated. For more information, see Activate Hybrid Cloud Monitoring.

Background information

Call this operation to obtain an initial cursor, and then call the BatchExport operation to export monitoring data.

Usage notes

This topic provides an example to define the export scope for the cpu_idle metric of the acs_ecs_dashboard cloud service at a 60-second interval from 1641627000000 (2022-01-08 15:30:00) to 1641645000000 (2022-01-08 20:30:00). The response displays the Cursor information.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
Namespace	string	Yes	The data namespace of the cloud service. For more information about how to obtain the data namespace of a cloud service, see Cloud service monitoring metrics.	acs_ecs_dashboard
Metric	string	Yes	The name of the metric for cloud service monitoring. For more information about how to obtain the metric name for cloud service monitoring, see Cloud service monitoring metrics.	cpu_idle
Period	integer	Yes	The time interval of the metric. Unit: seconds. Note The time interval of a metric is typically 60 seconds. For special values, see the `Period` parameter in Cloud service monitoring metrics.	60
StartTime	string	Yes	The start timestamp. The ISO 8601 format (YYYY-MM-DDThh:mm:ssZ) is supported. Example: 2023-01-01T00:00:00Z, which specifies 00:00:00 on January 1, 2023 (UTC). Note The time-to-live (TTL) of monitoring data in CloudMonitor varies with the time granularity. Refer to the data TTL corresponding to the `Period` request parameter to set a reasonable time interval.	1641627000000
EndTime	string	No	The end timestamp. Unit: milliseconds. Note UNIX timestamp: the number of milliseconds that have elapsed since January 1, 1970. The ISO 8601 format (YYYY-MM-DDThh:mm:ssZ) is also supported. Example: 2023-01-01T00:00:00Z, which specifies 00:00:00 on January 1, 2023 (UTC). If you do not specify the end time, the end time is infinite. In real-time export scenarios, you can leave this parameter empty. The TTL of monitoring data in CloudMonitor varies with the time granularity. Refer to the data TTL corresponding to the `Period` request parameter to set a reasonable time interval.	1641645000000
Matchers	array	No	The dimension information of the metric.
	Matcher	No	The dimension information of the metric.
