Methods and apparatus for managing quality of service of computing resources are presented. For example, a method implemented on a processor for managing quality of service of computing resources includes identifying, by the processor, one or more devices of a user on a network of the user; obtaining, by the processor, at least one management module for the identified one or more devices; installing the at least one management module in the processor; monitoring, by the processor, the one or more devices of the user for a problem; and determining, by the processor, a domain in which a root cause of the problem resides and, optionally, the root cause of the problem. The management module comprises information pertaining to a corresponding device. Further, the method may detect quality of service (QoS) problems and determine if the problems reside in a user domain or a service provider domain.
