HP GlancePlus User's Manual (for MPE/iX Systems)

Workload Screen 

The Workload screen summarizes activity for user-defined collections of
processes called applications.  You can use it to view information on
resource usage and transactions for groups of specific processes.
Application definitions are specified in a configuration file (for more
information, see appendix D).

The detail area of the display is divided into two parts:

   *   Interesting Applications.
   *   Top CPU Consumer and Top Disc Consumer.


          Figure 5-14.  Workload Screen 

Interesting Applications 

The Workload screen displays only applications that use CPU during the
interval to allow you to concentrate on applications currently affecting
performance.  Interesting applications scroll down as new entries are
added to the top of the listing thus keeping the latest information just
below the Global bars.  You can scroll the terminal display to examine
previous applications and intervals again.  You can also press the A key
to see a one-time display of all applications.

Some interesting applications will have fields highlighted to indicate an
event that might require closer attention.  On colored monitors, these
highlights are in color, on monochrome monitors they are underlined.

Since applications represent groups of processes, the thresholds for CPU
usage, disc transfers, and transaction rate are set higher than they are
for single processes.  These values are set by highlight specifications
in the GlancePlus configuration file GLANCNFG. Since response time is an
average for all processes in the application, the response time threshold
value used for single processes is also used for applications.  See
chapter 7 for more information on customizing GlancePlus.

Interesting Application Fields 

The application bars and fields appear below the Global bars and present
information about how the applications are using CPU and Disc resources
and information on their transaction rates and response times.

The Application bars and fields contain the following information: 

Application  This is the name of the application as specified
Name         in the application definitions (see appendix D).

CPU          This CPU bar shows the percentage of central
             processing unit time used by the application
             during the last interval.

             The bar contains the following codes: 

                *   L - Linear queue (AS or BS).
                *   C - CS queue.
                *   D - DS queue.
                *   E - ES queue.

             The number at the right of the bar is the
             percentage of time the application used the CPU
             during the last interval.  A bar will not be
             displayed if the percentage of CPU used was not
             high enough to occupy one character space on the
             bar.

          Table 5-1.  (cont.) 

DISC         This bar shows the application's disc transfer
             rate (transfers/second) during the interval.

             The bar contains the following codes:

                *   R - Disc reads.
                *   W - Disc writes.

             The number at the right of the bar is the
             application's disc transfer rate during the
             interval.

TRN          This field indicates the rate of terminal
             transactions (number/minute) during the last
             interval.

RESP         This field indicates the average terminal
             response time (seconds) during the last
             interval.

Top CPU and Disc Consumer 

GlancePlus names the processes that are consuming the most CPU resources
and the most Disc resources on the two lines following the application
bars and summary fields.

The top CPU consumer is identified by its PIN (process identification
number), the percentage of CPU it used during the last interval, and the
program name or MPE/iX Command Interpreter (CI) command last issued.  If
an MPE/iX system process is the top consumer, it is identified by the
program name or by the text:  running program on behalf of MPE/iX.

The top Disc consumer is identified in the same way as the top CPU
consumer except that the rate of disc transfers (transfers/second) for
the process during the last interval is displayed instead of CPU
percentage.  If no disc activity occurred during the interval, the Top
Disc Consumer line will not appear on the screen.


NOTE  If you do not have System Manager (SM) capability, you will see the
      letters CI instead of the command string text when the program is a
      Command Interpreter.
