Claim Text:
1. A method of diagnosing a root cause of a problem in a component of a data storage system, the method comprising: collecting current state data of the component in the data storage system over a current period of time, the current state data indicating a current state of the component at instants of time within the current period of time, the current state of the component at an instant of time being defined by current values of parameters of a set of parameters that describe the component; extracting, from storage, previous state data of the component in other data storage systems over a previous period of time, the previous state data indicating a previous state of the component at instants of time within the previous period of time, the previous state of the component at an instant of time being defined by previous values of the parameters; performing a comparison operation on the current state data and previous state data, the comparison operation generating a comparison result that indicates a difference between i) the current values of parameters over several of the instants of time within the current period of time and ii) the previous values of the parameters over several of the instants of time within the previous period of time; and mapping the difference to an anomalous behavior of the component over the current period of time, the anomalous behavior providing a diagnosis of the root cause of the problem.
