ResumeProcesses - Auto Scaling - Alibaba Cloud Documentation Center

Resumes suspended processes in a scaling group. This operation allows Auto Scaling to proceed with executing these processes according to their predefined rules and logic. For example, if you resume the health check process in your scaling group, Auto Scaling automatically detects and removes any instances deemed unhealthy from the scaling group.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
