How to get WEB APPS VMs information

Hi,

1. Through Service management API, we get hosted services and related VMs. However, for VMs related to "WEB APPS", those are not exposed. How can we get such VMs and their performance metrics?

2. Are VMs related to "WEB APPS", managed by Microsoft i.e. no administration possible for those VMs?

Thanks and Regards,
