Connections Workspace
The Connections workspace displays information that identifies current
connections and performance information on connections with current activity.
The Connections workspace displays the following views:
- Current Byte Rate >= 2048 - This bar chart displays
the number of bytes sent or received, per minute, during the most recent time
interval by connection number or ID.
- Current Datagram Rate > 0 - This bar chart displays
the number of datagrams, per minute, transmitted to or from connections during
the most recent time interval.
- Current Retransmits > 0 - This bar chart displays
the retransmits in the last sample and the total retransmits by connection
number or ID.
- Response Time > 0.2 Seconds - This bar chart displays
the response time and response time variance, in 1/10 seconds, by connection
number or ID.
- Connections Summary Table - Displays performance
summary data for each TCP/IP connection.
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 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).
