I/O operations which are directed to a set of storage resources and received at a data storage system from a first application are monitored. First information characterizing the I/O operations from the first application is collected in accordance with said monitoring. Using the first information, a first execution profile for the first application characterizing I/O operations of the first application is determined. It is determined whether the first execution profile of the first application matches any of a set of predetermined execution profiles for known applications. Each of the predetermined execution profiles characterizes I/O operations of one of the known applications. First processing is performed in accordance with one or more criteria including whether the first execution profile matches any of the set of predetermined execution profiles. ## Claims ### Claim 1 A method of analyzing storage resources comprising: monitoring I/O operations received at a data storage system from a first application, said I/O operations being directed to a set of one or more storage resources;
