This report shows what percent of the time each of the system dispatching queues was a given length. There are nine queues reported on in two separate reports. In report 151A, the In and Ready queue length percentages are reported. In 151B, the following queues are reported on: In, Out and Ready, Out and Waiting, Logical Out and Ready, Logical Out and Waiting. Along with the dispatcher queues, the percentage of the Ready counts are produced for these five types of address spaces/processes: Batch, Started Tasks, TSO, APPC/MVS Scheduler, Unix System Services.
This report could be used to determine if a system needs tuning. For example, if the longer Out and Ready queue lengths seem to have a high percentage, it may mean that more real memory is needed for a given system.
