1. API Description

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

This API is used to 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 obtain the data of up to 10 instances and up to 1,440 data points.
This API may fail due to the rate limit if you need to call a lot of metrics and objects. We recommended that you spread the call requests over time.

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

Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: monitor.ap-shanghai-fsi.tencentcloudapi.com

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.
