TCP/IP Summary History workspace

The TCP/IP Summary workspace displays historical performance data for the general health and activity of the TCP/IP stack. A TCP/IP protocol stack is uniquely defined within a z/OS® system image by the TCP/IP job name and the fully qualified host name or IP address. This workspace displays the most recent 24 hours of historical data by default.

Short Term History support is an optional feature that must be enabled for this workspace to display attribute and metric values. If this workspace does not contain data, you will see message KFWITM220E Request failed during execution. displayed in the Tivoli Enterprise Portal message area. Contact your system administrator to request that historical collection be started for this attribute group.

Note: If the address space being monitored is running on z/OS v1.11 or earlier, the values for this attribute group are retrieved using SNMP. If the address space being monitored is running on z/OS v1.12 or later, the values for this attribute group are retrieved using the z/OS Communications Server callable network management interface (NMI).

TCP/IP Summary History Summary table

The TCP/IP Summary History table provides detailed performance information about the TCP/IP stack displayed in the charts on the TCP/IP Summary History workspace for the specified time period.

The attributes displayed in the history workspace represents a subset of the attributes supported by the TCP/IP Summary workspace (for enhanced performance). For a complete list of the attributes available in the TCP/IP Summary History Summary table, and a brief description of each, see the TCPIP Summary Attributes help panel. Because this is a history panel, a unique attribute is listed in addition to the TCP/IP Summary attributes:

Recording Time
The time and date of the data sampling. Recording time displays the exact collection interval boundary (such as every 00:15:00 minutes). This value is displayed in the following format:
