ERXT0162/EZXT0162: XCF Path Activity

This report lists all XCF paths into and out of a system, whether they are channel-to-channel adapters (CTCAs) or coupling facility structures. The report lists the path definition (which is the structure name or the device addresses on both the local system and the remote system) as well as the transport class for the path. The number of messages sent and/or received for each path (CTCA paths are one way, CF structure paths are bidirectional), the average queue length, and the times a path was selected when it was busy versus when it was not busy.

With this, a path that is causing a bottleneck can be seen if the average queue length is very high.
