Performance

There are counters that provide information about the number of messages, bytes, and packets sent and received for each TCP/IP application. This information is provided in the reports that are generated by data collection and reduction. The counts are incremented differently based on whether or not the application is defined in the TCP/IP network services database. See TCP/IP Network Services Database Support for more information about this data collection and how to define your applications in the TCP/IP network services database. See TPF System Performance and Measurement Reference for more information about data collection and reduction in general.

The ZSTAT command display shows the total number of weighted TCP/IP messages. See TCP/IP Network Services Database Support for more information about weighted TCP/IP messages. See TPF Operations for more information about the ZSTAT command.

The ZTTCP DISPLAY STATS command display shows the total number of packets sent and received by the TPF system. You can display this information periodically and calculate the rate at which packets are transferred between the TPF system and IP routers.

The ZVIPA command displays statistical information about your TPF system and can be used to balance the OSA TCP/IP workload. For more information, see Workload Balancing Using Movable VIPAs.
