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.
- Round Trip 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. This field is filled in by default with
the value from the Foreign Address column for the selected
connection, but you can change this value to be any IPv4 or IPv6 address.
If the Foreign Address column is blank, the field will display IP address
that matches all addresses. With this address as input, this link navigates
to the Current IP Filters By Destination Address Workspace showing the IP
filters that match the IP address that you provided.
- 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).
