TCP Connections workspace
The TCP Connections workspace provides performance data 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 following product-specific Take Action Commands can
be issued from this workspace:
Take Action command |
Attribute |
Drop Connection |
Hex Connection Number |
NSLookup IP Address |
Remote IP Address |
Ping IP Address |
Remote IP Address |
Tracerte IP Address |
Remote IP Address |
For more information, see Take Action Commands.
The TCP Connections workspace displays the following views:
- Response Time Variance > 5 msec: Displays
response time variance by connection number or ID in a bar chart.
- Retransmission Rate > 0: Displays retransmissions
per minute by connection number or ID in a bar chart.
- Byte Rates for TCP Connections: Displays
the bytes sent and received, per minute, by connection number or ID
in a bar chart, where:
- Yellow represents Transmit Byte Rate.
- Blue represents Receive Byte Rate.
- Segment Rates for TCP Connections: Displays
the segments sent and received, per minute, by connection number or
ID in a bar chart, where:
- Yellow represents Transmit Segment Rate.
- Blue represents Receive Segment Rate.
- 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(R) Tivoli(R) NetView(R) for z/OS(R) 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).
