TCP Connections Workspace
The TCP Connections workspace provides performance for TCP connections
with current activity.
Though the Connections workspace is the default workspace accessed from
branches on the Navigator physical tree, the TCP Connections workspace can
also be displayed by doing the following:
- Click the Connections Navigator item.
- Right-click the Connections Navigator item.
- Select Workspaces and select the TCP Connections from the menu.
The TCP Connections workspace displays the following views:
- Response Time Variance > 5 msec - This bar chart
displays response time variance by connection number or ID.
- Retransmission Rate > 0 - This bar chart displays
retransmissions per minute by connection number or ID.
- Byte Rates for TCP Connections - This bar chart
displays the bytes sent and received, per minute, by connection number or
ID.
- Segment Rates for TCP Connections - This bar chart
displays the segments sent and received, per minute, by connection number
or ID.
- TCP Connections Summary Table - Provides detailed
connections and performance information.
TCP Connections Summary Table
The TCP Connections summary table provides detailed information about the
connections and performance data displayed in the charts on the TCP Connections
workspace.
The TCP Connections summary table filters the number of rows that can be
retrieved for display using the Byte Rate attribute.
The filter for this workspace is byte rate greater than or equal to 1024.
For a complete list of the attributes available in the TCP Connections
summary table, and a brief description of each, see the TCPIP Details Attributes help panel.
Note: If you clicked a link in an FTP or TN3270 workspace
to access the TCP Connections workspace and the TCP Connections workspace
displays no data, check the collection interval in the summary table on the
workspace you navigated from. If this is a new connection, there is no data
until the next collection has occurred.
These following additional workspaces can be accessed by left-clicking
on the Link icon for a row in the TCP Connections Summary
Table:
- Current IP Filters by Destination Address Workspace:
If the Connection Type is TCP, this link causes a dialog
box to be displayed that prompts you for a destination IP address that is
compared to the currently active filters for a TCP/IP stack. The IP address
input field in the dialog box is filled in by default with the value from
the Destination Address column for the selected filter,
but you can change this value to be another IPv4 or IPv6 address found on
this TCP/IP stack. Specify an IP address that has the same IP address version
as the selected connection. If you specify an IPv6 address and the selected
connection has an IPv4 address, then the linked-to workspace will not find
any filters to display. Note that if the Destination Address column in the summary table is blank, the IP address input field in
the dialog box is filled with an IP address that has a value of zero (0) for
all subnets in the address.
- IBM Tivoli NetView for z/OS DVIPA Definition and Status
Workspace: This link uses the IP address specified by the Local IP Address attribute to link to the NetView DVIPA Definition and
Status Workspace. This conditional link is available only if the DVIPA attribute
in these workspaces has the value of Yes (1).
