    1. API Description

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

    This API is used to trigger a command on the specified instance and returns the execution activity ID (inv-xxxxxxxx) on success. Each execution activity 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.
