Once the parameters for the TCP/IP components of the network have been set up and NV4IP is active on the Host, you are ready to monitor the network. It may be that only workload data is collected for a period of time until a feel for the network load has been determined. Workload monitoring does not require the Master to execute a Start Monitoring Command. The information collected is written to the NV4IP SMF record type (default: 251) and may be reviewed in the Real-Time Graphs/Reports module. The record contains the IP address of the resource, the packet sizes sent/received, and the round trip response time measured in milliseconds.
Real-time response time monitoring of your network requires that the Master workstation execute a Start Monitoring command. Once monitoring has been turned on, four packets of the size and for the frequency determined by you are sent to the critical resources defined for each Host Monitor. The Start Monitor command need only be done once at the Master for each Host being monitored. SysPoint provides an overview of all Hosts being monitored, and multiple hosts may be monitored simultaneously. Once you select a Stack for further study, only one host can be viewed at a time, so you will need to change Hosts in order to view all results. If you specify AUTOMON=YES in the AESTCPIP PROC, each time the Host Monitor is restarted, it automatically collects performance data for the critical resources that were last being monitored.
Access Real-Time Monitoring to interrogate mission critical application service levels and identify potential performance bottlenecks.
To begin monitoring, complete the following steps:
1. Click Start Monitoring from the Master Selections screen. The Select Resources to Start Monitoring screen appears.
2. From the table, select the resource(s) you wish to start monitoring by placing a checkmark in the Select column.
3. Click Start Monitoring. The following message appears: Monitoring started successfully for the resources selected.
4. Click on the Master tab to return to the Master Selections screen or, to start monitoring on another host, click the Change Host icon in the menu bar.
To stop monitoring, complete the following steps:
1. Click Stop Monitoring from the Master Selections screen. The Stop Monitoring screen appears. (If you are monitoring multiple hosts, you may need to use the Change Host option to access those resources you wish to stop monitoring.)
2. From the table, select those resource(s) you wish to stop monitoring.
3. Click Stop Monitoring. The following message appears: Monitoring stopped. It may take up to 15 seconds for all activity to stop completely.
4. Click on the Master tab to return to the Master Selections screen.
