Performance Management Assistant scans the load, job, and procedures libraries you define and locates all changed modules. Additionally, SMF job step termination (SMF 30, subtype 4) records are read, statistics calculated, and current consumption values checked for anomalies.

The measurements are stored for accessibility through the online panels for up to 18 months.
