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.
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:
|
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 About Viewing Alerts on page 66 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. |
