1. API Description

Domain name for API request: cdb.intl.tencentcloudapi.com.

This API is used to search for instance slow logs under usage conditions. Only allow viewing slow logs within one month.
During use, pay attention: a single slow log may be too large, causing the entire http request return content to be too large, furthermore leading to API timeout. Once timed out, narrow down the Limit parameter value when querying, thereby reducing the size and enabling the API to return content promptly.

A maximum of 50 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.
