1 Overview of HP StorageWorks XP Performance Monitor Performance Monitor lets you obtain usage statistics about physical hard disk drive, volumes, processors or other resources in your storage system. Performance Monitor also lets you obtain statistics about workloads on disk drives and traffic - HP XP24000 | HP StorageWorks XP24000 Performance Monitor User's Guide, - Page 14
