Channel Path Activity Report (Analyzer report)
The Channel Path Activity Report, in the figure below, shows information about the input/output definition file (IODF), and about the channels, including utilization percentages, channel speed, and read and write rates.
It is produced by using the CHANNEL Analyzer control statement. The data is obtained by using CHANNEL Extractor control statements.
This report can have the following sections:
- IODF Section
This section shows information about the input/output definition file (IODF). - Overview of DCM Channels
