System Report - Communications Summary

The Communications Summary section of the System Report shows the use of the communications lines and processors.

Example

Note: The line utilization in the sample system report shown does not correspond with the "Component Report - IOP Utilizations" for an IOP running SDLC remote work stations. A low SDLC line utilization value results in a high IOP utilization value due to polling. However, because the SDLC line transfers a larger percentage of user data, an IOP polls less frequently. Usually this results in an overall increase in IOP utilization. In some cases, though, especially when the SDLC lines have a low utilization, this results in an overall decrease in IOP utilization. Thus, a high IOP utilization value is significant only if at least one of the attached SDLC lines is active.

The values that display in the report header reflect the configuration metrics obtained from the QAPMCONF file when the collection started. These values might change for each interval within a collection period due to dynamic changes in logical partition configuration.
