Observing response times

There might be times where you are interested in monitoring response times for single users and groups of users. This may be the case if you have defined service level agreements based on response times, or if you get complaints from users about slow response times on the system. For this task, you will call the

• Monitor III - Sysplex Summary Report: This report displays the average response time for each service and report class period.

If you would like more information about one specific service class period, use the cursor-sensitive control of the Monitor III to navigate directly to the

• Monitor III - Response Time Distribution Report: With this report, you get detailed data for the service class period you are interested in:
  • If you have defined a response time goal for a service class period, you see a response time distribution graphic which is the lowest level of detail that is available.
  • In any case, you see the response time for each system from which this period is getting service.

If you want to concentrate on a single system, you get response time data from the

• Monitor III - System Information Report: This report shows the average response time for all workloads and service classes.

You get more detailed data for one group with the

• Monitor III - Group Response Time Report: The average response time is displayed as time that is split up into using and delayed time frames, so you can see how much time this group of address spaces was using the system resources, and how much time was spent waiting for resources.

If you need response time data for longer periods of time, then you will work with Monitor I data. Get the information by creating a

• Postprocessor - Workload Activity Report: This sysplex report provides response times for all service class periods and — if you have defined response time goals — response time distribution information. You select the level of detail by the corresponding report options.
