Metrics Option 

The Metrics option is an unlabeled list box on the Forecasts command
dialog box.


            

You can forecast the following metrics:

   *   Global CPU Utilization. 

       Global CPU Utilization represents the percentage of elapsed time
       the CPU is busy executing instructions.

   *   Session CPU Utilization. 

       Session CPU Utilization is the percentage of elapsed CPU time
       spent executing instructions for interactive processes (sessions).

   *   Job CPU Utilization. 

       Job CPU Utilization is the percentage of elapsed CPU time spent
       executing instructions for batch processes (jobs).

   *   Transaction Rate. 

       Transaction Rate is the number of terminal transactions per hour.
       Each unit on the graph represents 1000 transactions.

       A terminal transaction is the activity that occurs between reads
       issued to a terminal.

       Interactive and job processes (but not system processes) read and
       write to a terminal and can generate terminal transactions.

   *   Phys Disc I/O Rate. 

       Physcial disc I/O rate is defined as the number of transfers per
       second made to or from the disc drives on behalf of user programs.
       It does not include transfers used in managing memory.

       This is an indication of overall disc activity.

   *   Disc Utilization. 

       Disc Utilization is the percent of time when transfers to or from
       the disc are in progress.

   *   First Response. 

       First Response is the time between pressing return-enter on the
       keyboard and the writing of the first line to the terminal screen.

   *   Response to Prompt. 

       Response to Prompt is the time between pressing return-enter and
       the next prompt to the user.

   *   Memory Manager I/Os. 

       Memory Manager I/Os is defined as the number of transfers per
       second made to or from the disc drives on behalf of the memory
       manager.

       This is an indication of swapping or memory management overhead.

   *   Busy Sessions. 

       Busy Sessions is defined as the average number of interactive
       sessions that had any activity.

   *   Busy Jobs. 

       Busy Jobs is defined as the average number of batch jobs that had
       any activity.

   *   Application CPU Utilization. 

       Application CPU Utilization is defined as the percentage of
       elapsed time that the CPU is busy executing instructions on behalf
       of the application.

   *   Application I/Os. 

       Application I/Os refers to physical application I/Os for the
       application you specified.  It is defined as the number of
       transfers per second made to or from the disc drives on behalf the
       application.

       It does not include transfers used in managing memory.

   *   Application First Response. 

       Application First Response is defined as the time between pressing
       return-enter on the keyboard and the writing of the first line to
       the terminal screen.

   *   Application Response to Prompt. 

       Application Response to Prompt is defined as the time between
       pressing return-enter and the next prompt to the user.

   *   Application Transactions. 

       Application Transactions is defined as the number of terminal
       transactions per hour.  Each unit on the graph represents 1000
       transactions.

If the highlighted logfile in the Available Logfiles list box does not 
contain any application data, the Metrics list box does not display
application metrics (the last five metrics listed above).

You can select multiple graphs by holding down the Shift key and clicking
the mouse on additional metrics you want to forecast.
