Hi @msyyc. Is the issue still valid? if you don't mind, I want to deal with it about metricsadvisor.

@wonder6845 This issue is mainly for mgmt package. I am not sure which version of autorest.python you use to generate azure-ai-metricsadvisor. You can refer to https://github.com/Azure/autorest.python/blob/autorestv3/packages/autorest.python/ChangeLog.md to update your min dependency.
