SysPoint Screen

The SysPoint screen provides an overview of network activity for Operations, Systems, and Network staff. The data is displayed in a table for quick reference and provides the ability to drill down by clicking in a cell when further information is needed. The SysPoint screen provides information on Hosts, Alerts, stack workload, channel activity, and traffic for connections.

Figure 17. SysPoint

The fields on the SysPoint screen are:

Stack Name

Host name of the TCP/IP stack as defined in the TCPIP.DATA dataset.

Stack IP Address

IP address of the selected host.

CSM Buffer Alerts

There are two types of Buffer Alerts:

  • Low Availability
  • High Usage

Link Alerts

Total count of Alerts sent during the current time period for channel links found in a Not Ready state for the channel device or link and/or for exceeding the queue size.


 

Port Alerts

Total count of Alerts sent during the current time period for unavailable ports.

Session Alerts

Total count of Alerts sent during the current time period for applications/sessions that have exceeded the threshold values for throughput, data size, and/or hung sessions.

Crit. Res. Avail. Alerts

Total count of Alerts sent during the current time period for Critical Resources that were unreachable (Ping command timed out).

Crit. Res. Perf. Alerts

Total count of Alerts sent during the current time period for Critical Resources that exceeded the value set for acceptable response time when the device was defined in the Master.

Stack Bytes In

Total number of bytes received by this connection since the last sampling interval.

Stack Bytes Out

Total number of bytes sent by this connection since last sampling interval.

Total Channel Links

Count of all the channel-attached processors and links associated with the selected TCP/IP address space for the current time period.

Not Ready Channel Links

Count of those channel links showing a status of Not Ready.

Not Ready Channel Device s

Count of those channel processors showing a status of other than Ready. These states could be any of the following conditions: Starting, Sent SETUP request, Enabling, Connecting, Connecting2, Negotiating, Deactivating or Not Ready.

Active Listeners

A Listener session is established and application transactions are occurring between the remote port and the TCP/IP application. The Listeners group contains ports and applications which have at least one "Listener" session. A Listener session allows remote ports to connect to the TCP/IP application on the mainframe.

InActive Listeners

A Listener session is established but no activity is present.

UDP Sessions

Total number of User Datagram Protocol instances since last sampling interval.

TCP Sessions

Total number of Transfer Control Protocol instances since last sampling interval.

% Avail. Critical Resources

Percentage=((All monitored Critical Resources-Unavailable Critical Resources)/All monitored Critical Resource) * 100%

Further analysis can be done using the SysPoint's drill-down features: Alerts, LinkView, and Connect Expert. Each feature is briefly described below:

Alerts

When an Alert occurs for a stack during the current interval, the Alert shows in red. The SysPoint screen provides a count per Alert for the listed activities and a drill-down capability for Alerts. SysPoint provides both Summary and Detail Reports by Alert Type to assist in the analysis of related network problems. To obtain further information about a particular Alert, simply place your cursor in the appropriate cell and click. Refer to Viewing Alerts for further information.

LinkView

To obtain further information on channel link activity in real time or near-time IP throughput information on channel-attached devices, use LinkView. LinkView shows all the channel-attached processors and links associated with your TCP/IP address space on one screen. Channel-attached processors include Channel-to-Channel devices, LAN channel stations, ATM devices, CLAW devices (ex: RS 6000s), FDDI devices, or router cards such as the CISCO CIP card. The LinkView screen also provides access to the Thru24 Summary/ Detail reports which show near-time IP throughput data for channel-attached devices.

LinkView is accessed from the SysPoint screen by clicking on a Stack IP Address and then clicking Show LinkView from the drop-down menu.

Connect Expert

Connect Expert allows you to view UDP (EE and non-EE) workload/session connectivity information as well as monitor sockets and the connectivity to all your sessions in real time. You can also view further UDP details (EE and non-EE) by accessing the Enterprise Extender Expert or UDP report, or zoom in to any port/application or session to view TCP/IP details using the Port Workload/Port Details reports.

Connect Expert is accessed from the SysPoint screen by clicking on a Stack IP Address and then clicking Show Connect Expert from the drop-down menu.
