DescribeLimitation - Auto Scaling - Alibaba Cloud Documentation Center

Queries resource quotas. You can call the DescribeLimitation operation to query the upper limits on resources such as scheduled tasks that can be created in a scaling group, load balancers that can be attached to a scaling group, instances that can be contained in a scaling group, and scaling configurations that can be created in a 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.
