1. API Description

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

This API is used to execute a command and returns the execution activity ID (inv-xxxxxxxx) on success. Each execution has one or more execution tasks (invt-xxxxxxxx) and each execution task indicates an execution record on a CVM or Lighthouse instance.

  • If the agent is not installed on the instance or is offline, an error is returned.
  • If the command type is not supported by the agent runtime environment, an error is returned.
  • The specified instance needs to be in a VPC network.
  • The specified instance needs to be in the RUNNING status.
  • Only one type of instances (CVM or Lighthouse) can be specified in a single request.

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.
