GetMonitorData

Last updated: 2021-10-13 10:54:42

1. API Description

Domain name for API request: monitor.tencentcloudapi.com.

This API is used to get the monitoring data of Tencent Cloud services except TKE. To pull TKE’s monitoring data, please use the API DescribeStatisticData.
You can get the monitoring data of a Tencent Cloud service by passing in its namespace, object dimension description, and monitoring metrics.
API call rate limit: 20 calls/second (1,200 calls/minute). A single request can get the data of up to 10 instances for up to 1,440 data points.
If you need to call a large number of APIs to pull metrics or objects at a time, some APIs may fail to be called due to the rate limit. We suggest you evenly arrange API calls at a time granularity.

A maximum of 20 requests can be initiated per second for this API.

We recommend you to use API Explorer
Try it
API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

2. Input Parameters

The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

Parameter Name Required Type Description
Action Yes String Common parameter. The value used for this API: GetMonitorData.
Version Yes String Common parameter. The value used for this API: 2018-07-24.
Region Yes String Common parameter. For more information, please see the list of regions supported by the product.
Namespace Yes String Namespace, such as QCE/CVM. For more information on the namespaces of each Tencent Cloud service, please see Tencent Cloud Service Metrics
MetricName Yes String Metric name, such as CPUUsage. Only one monitoring metric can be pulled at a time. For more information on the metrics of each Tencent Cloud service, please see Tencent Cloud Service Metrics. The corresponding metric name is MetricName.
Instances.N Yes Array of Instance The dimension combination for instance objects, which is in the form of a set of key-value pairs. The dimension fields for instances of different Tencent Cloud services are completely different. For example, the field is [{"Name":"InstanceId","Value":"ins-j0hk02zo"}] for CVM instances, [{"Name":"instanceId","Value":"ckafka-l49k54dd"}] for CKafka instances, and [{"Name":"appid","Value":"1258344699"},{"Name":"bucket","Value":"rig-1258344699"}] for COS instances. For more information on the dimensions of various Tencent Cloud services, please see Tencent Cloud Service Metrics. In each document, the dimension column displays a dimension combination’s key, which has a corresponding value. A single request can get the data of up to 10 instances.
Period No Integer Monitoring statistical period in seconds, such as 60. Default value: 300. The statistical period varies by metric. For more information on the statistical periods supported by each Tencent Cloud service, please see Tencent Cloud Service Metrics. The values in the statistical period column are the supported statistical periods. A single request can get up to 1,440 data points.
StartTime No Timestamp ISO8601 Start time such as 2018-09-22T19:51:23+08:00
EndTime No Timestamp ISO8601 End time, which is the current time by default, such as 2018-09-22T20:51:23+08:00. EndTime cannot be earlier than StartTime

3. Output Parameters

Parameter Name Type Description
Period Integer Statistical period
MetricName String Metric name
DataPoints Array of DataPoint Array of data points
StartTime Timestamp ISO8601 Start time
EndTime Timestamp ISO8601 End time
RequestId String The unique request ID, which is returned for each request. RequestId is required for locating a problem.
