Connections Workspace
The Connections Workspace displays information that identifies
current connections and performance information on connections with
current activity.
This workspace is displayed by clicking on the Connections Navigator
item of any monitored TCP/IP stack.
The Connections workspace displays the following views:
- Current Byte Rate >= 2048: Displays the
number of bytes sent or received, per minute, during the most recent
time interval by connection number or ID as a bar chart.
- Current Datagram Rate > 0: Displays the
number of datagrams, per minute, transmitted to or from connections
during the most recent time interval as a bar chart.
- Current Retransmits > 0: Displays the retransmits
in the last sample and the total retransmits by connection number
or ID as a bar chart, where:
- Yellow represents Retransmits Last Sample.
- Blue represents Total Retransmits.
- Response Time > 0.2 Seconds: Displays the
response time and response time variance, in 1/10 seconds, by connection
number or ID as a bar chart, where:
- Yellow represents Response Time.
- Blue represents Response Time Variance.
- Connections Summary Table: Displays
performance summary data for each TCP/IP connection.
The following product-specific Take Action Commands can
be issued from this workspace:

The Connections workspace can be displayed from the Connections
Navigator item of each monitored TCP/IP stack. Though the Connections
workspace is the default workspace, the following workspaces can also
be displayed by right-clicking the Connections leaf in the navigation
tree:
Connections Summary Table
The Connections Summary Table displays the collection time, connection
number, application name, and port number for each connection. It
also shows the following information:
- Byte rate
- Input and output bytes
- Datagram rate
- Input and output datagrams
- Retransmitted segments
- Round trip time and variance
The TCPIP 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 is
greater than or equal to 2048. For a complete list of the attributes
available in the TCPIP Connections Summary Table, and a brief description
of each, see the TCPIP Connections Attributes help
panel.
These following additional workspaces can be accessed by left-clicking
the Link icon for a row in the Connections Summary
Table:
- Current IP Filters by Destination Address:
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).
- NetView for z/OS: Packet
Trace - Start: Launches a session to Tivoli NetView for
z/OS V5.4 inside Tivoli Enterprise Portal using the Dynamic Link to
3270 feature, if the NetView program is configured for packet trace
and active on the system in which this instance of the OMEGAMON XE
for Mainframe Networks monitoring agent is running. This link launches
directly into the NetView for z/OS V5.4 product and starts NetView
IP packet trace for the selected connection. At the end of the process,
you are left in the NetView for z/OS PKTTRACE Control panel. You can
then view the captured packets from Tivoli Enterprise Portal or perform
other NetView functions once this script terminates.
- NetView for z/OS: Packet
Trace - Stop: Launches a session to Tivoli NetView for
z/OS V5.4 inside a Tivoli Enterprise Portal terminal view using the
Dynamic Link to 3270 feature, if the NetView program is configured
for packet trace and active on the system in which this instance of
the OMEGAMON XE for Mainframe Networks monitoring agent is running.
This link runs a script which stops IP packet trace for the selected
connection. At script termination, you are left in the NetView for
z/OS PKTTRACE Control panel. You can then view the captured packets
from Tivoli Enterprise Portal or perform other NetView functions
