Connect Expert Main Page

The Connect Expert screen is accessed by clicking a Stack IP Address hyperlink from the SysPoint screen and then clicking Show Connect Expert from the drop-down menu. You can also access Connect Expert by clicking its hyperlink under the Workload group in the Real-Time tab. If you are not logged on to the Host whose Stack IP Address you have selected to view, you are prompted for your User ID/Password and logged onto the selected Host after entering the requested information.

The Enterprise Extender Expert table at the top of the screen shows the current EE workload by port. The table shows the number of ports, bytes in/out, percent (of bytes) in/out actually being used by the port, and the throughput in bytes per second.

The UDP Sessions (non-EE) table shows the application name, port number, bytes in/out, percent (of bytes) in/out actually being used by the port, and the throughput in bytes per second.

Two sets of data are shown in the two tables at the bottom of the screen: Listeners and TCP Sessions. The Listeners set displays applications and ports that have at least one "Listener" session running. A Listener session allows remote ports to connect to the TCP/IP application on the mainframe. If you do not have a Listener session for a particular application that uses Listener sessions, it may be an indication of a network problem. For example, if you want to have Telnet (TN3270) sessions, there must be a Listener active on the well-known Port 23.

Note:   Some applications do not use Listener sessions. Verify your application's design with your Systems Administrator.

The fields in the Connect Expert tables are:

Enterprise Extender

EE

The VTAM application name for Enterprise Extender on that system. Hyperlink to the Enterprise Extender Expert report to view details on the current EE UDP workload for each of the assigned EE ports.

Number of Ports

The count of ports assigned to the EE application.

Bytes In

Number of bytes coming in to all assigned EE UDP ports.

Percent In

Percentage of bytes received relative to the total number of bytes coming in for all assigned EE UDP, UDP (non-EE), and TCP ports.

Throughput In Bytes/Sec

Data transfer rate inbound in bytes per second.

Bytes Out

Number of bytes transmitted out from all assigned EE UDP ports.

Percent Out

Percentage of bytes received outbound relative to the total number of bytes transmitted out for all assigned EE UDP, UDP (non-EE), and TCP ports.

Throughput Out Bytes/Sec

Data transfer rate outbound in bytes per second.

UDP Sessions (non-EE)

UDP

Name of non-EE UDP application. Hyperlink to the UDP report.

Number of Ports

The count of ports currently in use by the UDP (non-EE) application.

Bytes In

Number of bytes coming in for all UDP (non-EE) sessions.

Percent In

Percentage of bytes received relative to the total number of bytes coming in for all assigned EE UDP, UDP (non-EE), and TCP ports.

Throughput In Bytes/Sec

Data transfer rate inbound in bytes per second.

Bytes Out

Number of bytes transmitted out for all UDP (non-EE) sessions.

Percent Out

Percentage of bytes received outbound relative to the total number of bytes transmitted out for all assigned EE UDP, UDP (non-EE), and TCP ports.

Throughput Out Bytes/Sec

Data transfer rate outbound in bytes per second.


 

Listeners

Name

Application name. The applications listed in the Listeners Name fields have Listener sessions active on the ports noted.

Port

Local port number. An application may be active on more than one port. The ports listed in the Listeners Port fields have Listener sessions active on the ports noted.

TCP Sessions

Name

Application name. Hyperlink to the Port Workload report to view details on the sessions for that application (all ports).

Port

Local port number. An application may be active on more than one port. Hyperlink to the Port Details report to view details on the sessions for that port.

Bytes In

Bytes in to TCP/IP on the mainframe since the session was started.

Percent In

Percentage of bytes received relative to the total number of bytes coming in for all assigned EE UDP, UDP (non-EE), and TCP ports.

Bytes Out

Bytes out to the remote IP address since the session was started.

Percent Out

Percentage of bytes received outbound relative to the total number of bytes transmitted out for all assigned EE UDP, UDP (non-EE), and TCP ports.

Number of Sessions

Total sessions.

Session Percent

The percentage of total sessions attributable to this local port or application.

Sessions Not Established

Total number of sessions in a status other than established by port. These sessions may need further investigation.

Sessions Time-Wait or Closed

Total number of sessions in a Time-Wait or Closed status. These sessions may need further investigation.
