Managing An Application's Resource Stack

Abstract

A method for managing an application's resource stack is disclosed. The method includes identifying, by a storage system, a root cause of an anomaly predicted at the external component that affects a performance of the storage system based on a relationship between metrics of the storage system and metrics of a component external to the storage system; and reconfiguring the external component based on the identified root cause.
