You can collect Event Monitor data (OpenVMS) or system accounting plus snapshot data (UNIX). Event Monitor data includes interactive think and response times per process and disk use per process. The Event Monitor data collector records process creation and deletion and image activation and deactivation.

The Data Collector window is displayed.
The Data Integrator processes measured, sampled, and event data collected by the data collectors. It produces a system resource use file and merged data file (.MERG or .merg) that can be used during workload characterization.
To integrate the collected data:

The Data Integrator window is displayed.
To draw a configuration:
or
The View Library window is displayed.
Characterizing a workload reduces the number of process profiles making up the workload into classes. It also builds and validates a base model.
To classify and model data:
or
The Workload Analysis window is displayed.
You can perform what-if analyses to predict performance and create a saturation analysis.
To perform a what-if analysis:
