The IBM iDoctor for IBM i PEX-Analyzer Service includes a software tool specifically geared towards pinpointing issues affecting system and application performance. The detailed analysis it provides picks up where the PM for Power Systems and Performance Tools products leave off and supplies a drill down capability that provides low-level summary of disk operations, CPU utilization, file opens, MI programs, wait states, DASD space consumption and much more.

The PEX-Analyzer client allows a user to create, delete, copy, save, FTP, and analyze PEX collections and create, change or delete PEX definitions. The client allows the user to graphically display PEX collection data to help quickly identify performance problems.
