TCP/IP Summary Workspace
The TCP/IP Summary workspace is a multi-pane workspace that shows
the general health and activity of the TCP/IP stack. It provides performance
data for the TCP layer of a z/OS(R) Communications
Server TCP/IP protocol stack that is running in z/OS system images.
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.
The TCP/IP Summary workspace is displayed when the TCP/IP Navigator
icon for a monitored stack is selected.
An alternate workspace is the TCP/IP Summary History workspace,
which displays historical performance data for the layers of the TCP/IP
stack during the specified time period. This workspace displays the
most recent 24 hours of historical data by default. This workspace
can be displayed by right-clicking on the TCP/IP Navigator icon for
a monitored stack. For more information, see TCP/IP Summary History Workspace.
The TCP/IP Summary workspace contains the following views:
- Resource Summary: Displays the count of
TCP/IP resources by type in a bar chart, where:
- Yellow represents the Gateway Count.
- Blue represents the Connection Count.
- Pink represents the Application Count.
- Green represents the Device Count.
- Turquoise represents the Telnet Session
Count.
- Traffic Summary: Displays the count of TCP/IP
resources by type in a bar chart, where:
- Yellow represents the Input Segment Count.
- Blue represents the Output Segment Count.
- Pink represents the TCP Input Segment Count.
- Green represents the TCP Output Segment
Count.
- Turquoise represents the UDP Input Datagram
Count.
- Orange represents the UDP Output Datagram
Count.
- Discard Percentages: Provides the following
data in a line chart, where:
- Yellow represents the Input Discard Percentage.
- Blue represents the Output Discard Percentage.
- Pink represents the UDP Discard Percentage.
- Fragmentation Percentages: Provides the
following data in a line chart, where:
- Yellow represents the Fragmentation Percentage.
- Blue represents the Fragmentation Failure
Percentage.
- Reassembly Percentages: Provides the following
data in a line chart, where:
- Yellow represents the Reassembly Percentage.
- Blue represents the Reassembly Failure Percentage.
- Retransmission Percentages: Shows the percentage
of TCP segments retransmitted over time in a line graph.
- Throughput Rate: Shows the byte rate, or
number of bytes received or sent, per minute, over time in a line
graph.
- TCP/IP Summary Table: Displays
the TCP/IP Summary attributes that can be used to view information
about TCP/IP stack conditions, find and fix problems in your network,
or create situations that monitor information for a selected TCP/IP
stack.
TCP/IP Summary Table
The TCP/IP Summary Table displays the TCP/IP Summary attributes
that can be used to view information about TCP/IP stack conditions,
find and fix problems in your network, or create situations that monitor
information for a selected TCP/IP stack.
The TCP/IP Address Space workspace and the TCP/IP Summary workspace
share a common attribute table, TCPIP_Address_Space. Only a subset
of the attributes are displayed in each workspace.For a complete list
of the attributes available in the TCP/IP Address Space Summary Table,
and a brief description of each, see the Address
Space Attributes help panel.
