XCF System Statistics workspace

The XCF System Statistics workspace displays information about cross system coupling facilities (XCF) signals (messages) sent between z/OS systems in the sysplex. The workspace lets you identify where changes to transport class definitions can be made to optimize XCF performance and resource utilization. You can link to this workspace from the XCF Systems table of the XCF Systems Data for Sysplex workspace.

The XCF System Statistics table provides the system from and the system to which the signals are sent, the transport class, the number of signals sent and received, the times the path or transport buffer was unavailable, the buffer length, the number of messages that fit or were larger or smaller than the buffer, and the percentage of all messages which were degraded because the length was larger than the buffer.

By default, the Times Path Unavailable, Times Buffer Unavailable, and Percent Degraded columns have predefined thresholds that trigger a warning indicator when the value is greater than 0.

This workspace also has a bar chart that graphically shows XCF outbound buffer utilization for the sysplex.
