MPE/iX Measurement Differences Some performance metrics are not available on all releases of the MPE/iX operating system. SCOPEXL is the Performance Collection Software data collector for MPE/iX systems. The way SCOPEXL calculates values for these metrics is described in the following sections. Individual Disc I/Os by Device Counts of individual disc I/Os by device are not available at the application level, therefore the total disc I/Os for the Application Detail data (zoom-by-application) are accumulated into a single disc device. On MPE/iX systems, counts of logical disc I/Os for an individual device will be available in a future release of the operating system. Until then, these values are set to zero on GLOBAL DISC DETAIL graphs.
