ΓòÉΓòÉΓòÉ 5. About CPU Monitor Plus ΓòÉΓòÉΓòÉ

Use CPU Monitor Plus to monitor and control the programs executing on your
computer.  CPU Monitor Plus provides you with facilities to:

 o Start and stop programs under your control;
 o Change the execution priority and state for a process or its threads;
 o Continuously monitor the CPU and RAM usage for processes and threads.

 Under OS/2, a program, its data, and its threads of execution are collectively
 called a process.  A process is created when a program is loaded into memory
 by the OS/2 system loader (part of the OS/2 kernel).

 Threads in a process run independently, each with their own stack and
 execution privileges.  OS/2 is multitasking in that threads from multiple
 processes all compete for and share the computer's CPU, memory, and device
 resources.

 CPU Monitor Plus allows you to closely examine and control the operation of
 OS/2.  You select the data that you want to monitor and how you want that data
 displayed.

 Use the File pull-down menu to:

 o Log CPU Monitor Plus output to a file;
 o Save or reset current display selections and preferences;
 o UnInstall CPU Monitor Plus;

 Use the Edit pull-down menu to copy the current CPU Monitor Plus display to
 the clipboard.

 The Commands pull-down menu allows you to:

 o Start a new process from CPU Monitor Plus;
 o Stop a currently executing process;
 o Change the execution priority of individual threads within a process;
 o Suspend a currently executing thread;
 o Instantaneously examine the current CPU Utilization data.

 Use the View pull-down menu to:

 o Select specific processes and threads to display;
 o Fully customize the CPU Monitor Plus display;
 o Choose from several useful predefined displays.

 Use the Options pull-down menu to customize, enable, and disable the display.
 Also use this to set the statistics gathering parameters.

 Additional help is available for all menu choices.

ΓòÉΓòÉΓòÉ 10.1.4. Statistics gathering frequency ΓòÉΓòÉΓòÉ

Use this to change the statistics gathering mode and frequency. There are two
different modes of operation:

 o Statistics gathering using the CPU Monitor Plus device driver;

 o Statistics gathering from CPU Monitor Plus

 The Slow, Normal, and Fast options specify that statistical data be collected
 by the CPU Monitor Plus device driver at a rate of 5, 10, and 32 times per
 second respectively.  Fast provides the highest level of accuracy for CPU
 utilization estimates.  Slow and Normal both provide high levels of accuracy
 while using less CPU time to gather the data.

 The Alternate mode specifies that CPU Monitor Plus itself gather all
 statistical information.  This method is less accurate than using the CPU
 Monitor Plus device driver, since CPU Monitor Plus runs only as a standard
 OS/2 application.  As such, its own CPU allocation is in contention with all
 other applications running on the system.

 BonAmi Software recommends using the Slow or Normal gathering frequency for
 most environments.  Use the Alternate mode to disables all statistics
 gathering by the CPU Monitor Plus device driver.

 Note:  The Alternate mode gathers data at a rate dependent on the display
 frequency. In general, shorter display frequencies provide higher accuracy for
 the Alternate method.  The display frequency rate has little effect when using
 one of the device driver modes.

 Refer to the CPU Monitor Plus User's Guide for more details on the statistics
 gathering options available in CPU Monitor Plus.

 The statistics gathering frequency may be modified in the Configure dialog.
 Select Configure from the Options menu or with the Ctrl-C hot key.


ΓòÉΓòÉΓòÉ 10.1.5. Display frequency ΓòÉΓòÉΓòÉ

Use this to change the display update frequency.  You may select any value
between 1 and 60 seconds.

Note:  When using the CPU Monitor Plus device driver, process statistics are
gathered independently of the display frequency.  Different display frequency
rates will influence statistics gathered by CPU Monitor Plus only when the CPU
Monitor Plus device driver is not used.

Refer to the CPU Monitor Plus User's Guide for more details on the statistics
gathering methods used in CPU Monitor Plus.

The display frequency can be automatically set when CPU Monitor Plus starts via
a command line switch.  See the CPU Monitor Plus User's Guide for details on
using the command line switches.

The display frequency may be modified in the Configure dialog.  Select
Configure from the Options menu or with the Ctrl-C hot key.

also disable logging output to a file.

Select the Enable menu item to restart the screen display.

Disable is selected from the Options menu or with the Ctrl-D hot key.


ΓòÉΓòÉΓòÉ 10.3. Enable ΓòÉΓòÉΓòÉ

Use this to enable the timed display of statistics to the screen.  By default,
the display is normally enabled.  If the Disable option has been invoked,
Enable will restart the timed display.  This will also restart logging output
to a file.

Enable is selected from the Options menu or with the Ctrl-E hot key.


ΓòÉΓòÉΓòÉ <hidden> Log File Help ΓòÉΓòÉΓòÉ

ΓòÉΓòÉΓòÉ <hidden> Configure Display Help ΓòÉΓòÉΓòÉ

Configure the CPU Monitor Plus display and statistics collection mode.  The
following parameters can be set:

Display Frequency

Enter the number of seconds to wait between screen updates.  You may select any
value between 1 and 60 seconds.

Note:  The CPU Monitor Plus device driver carries out statistics gathering
independently of the display frequency.  Nevertheless, the display frequency
influences statistics gathering when CPU Monitor Plus itself collects the
statistics without a device driver.

Refer to the CPU Monitor Plus User's Guide for more details on the statistics
gathering methods used in CPU Monitor Plus.

The display frequency can also be automatically set when CPU Monitor Plus
starts via a command line switch.  See the CPU Monitor Plus User's Guide for
details on using the command line switches.

Statistics Gathering Frequency

Enter the  desired statistics gathering frequency mode.  The Slow, Normal, and
Fast options specify that statistical data be collected by the CPU Monitor Plus
device driver at a rate of 5, 10, and 32 times per second respectively.  Fast

ΓòÉΓòÉΓòÉ <hidden> Display Process Data Fields Help ΓòÉΓòÉΓòÉ

Select the data fields to include in the Custom display.  Each of the fields is
described below.

 o Process ID is the unique identifier for every process.

 o Process Name is the name assigned to the current process.  More than one
   program with the same name or more than one instance of the same program may
   be simultaneously loaded for execution; use the Process ID to distinguish
   between these programs.

 o Process Priority has a two-part value.  The first digit is the priority
   class.  OS/2 gives a task with a higher priority class preference over a
   lower priority class.  The priority classes from lowest to highest are:

    - 1:  Idle Priority
    - 2-7: Regular and Foreground Priority
    - 8:  Time Critical Priority

      Each priority class has 32 levels, 0 the lowest priority and 31 the
      highest (0 to 1F in hexadecimal).

      Be aware that OS/2 normally adjusts each task's priority within a class
      dynamically, to insure that every task gets some CPU time.

      Note:  The Foreground (or fixed high) priority class actually has a
      higher priority than the Regular class.  This allows the current screen
      group to respond more favorably to an interactive user.

 o All Threads displays all the threads for each process.

 o State displays the execution state of a process or thread.  It may be Ready
   if the process or thread is ready or currently executing.  If the thread is
   not Ready, it may be Blocked or Frozen.

 o Session ID is the session or screen group identifier.

 o Parent's ID displays the parent's process identifier for each thread or
   process.

 o Total CPU Time displays the cumulative CPU time used by a process as
   recorded by CPU Monitor Plus.  Any time used by the process when CPU Monitor
   Plus was not enabled is not included.

 CPU Utilization values are displayed as specified below:

 o CPU Utilization will display a bar graph or decimal number representing the
   percent CPU time used by the process or thread during the last display
   period.

 o Idle Time displays the estimated percentage of the time that the CPU was
   idle during the last display period.

 Numeric fields are displayed in the current number base, either decimal or
 hexadecimal.  Percentages are always displayed in decimal.  The number base is
 changed from the Configure dialog.

ΓòÉΓòÉΓòÉ <hidden> Suspend Thread Help ΓòÉΓòÉΓòÉ

Select the process and thread to be suspended or resumed.  If the state for a
thread is displayed as 'Suspend', then that thread is currently suspended.
'Normal' indicates that the thread is not suspended.

Since OS/2 places restrictions on suspending threads in other processes, only
those threads belonging to most Presentation Manager programs can be suspended
or resume executing.

Press Refresh to update the display for any processes that have recently
terminated or started.  Be aware that CPU Monitor Plus retains process
information for a period of time dependent on the current display frequency.

Press Set to change the execution state for the selected thread.  Press Cancel
to return to the CPU Monitor Plus display.

Warning: It may NOT be possible to resume a process whose sole 'Message Loop'
thread has been suspended.  In many programs, the first thread (Thread 1) has
the responsibility for dispatching all messages for that process in a message
loop.  This thread is referred to as the message loop thread.  Therefore, if
you choose to suspend Thread 1 in any process, a warning will be displayed.

Suspended threads may sometimes be identified by a "Frozen" entry in CPU
Monitor Plus' "State" column.  "State" is included in the Custom View display
via the Fields menu item.

ΓòÉΓòÉΓòÉ <hidden> Installation Help ΓòÉΓòÉΓòÉ

Use the CPU Monitor Plus Setup program to install CPU Monitor Plus in your
system.  Setup performs the following operations:

 o Initializes the CPU Monitor Plus executable file;
 o Copies the program files to your hard disk;
 o Updates the CONFIG.SYS and OS2.INI files.

 CPU Monitor Plus can perform some installation functions itself.  These are
 limited to updating the OS2.INI file to automatically load the CPU Monitor
 Plus dynamic link libraries.  This feature may be useful if you reinstall CPU
 Monitor Plus after having previously selected UnInstall.

 To allow CPU Monitor Plus to install itself, select YES when prompted to
 continue with the installation.  CPU Monitor Plus will then backup and update
 the OS2.INI system file.  The CONFIG.SYS file is not updated, nor are any
 files copied to the hard disk.

 After installation is complete, the computer should then be restarted to
 enable all CPU Monitor Plus functions.

 Note:  Part of the installation process requires that the CPU Monitor Plus
 help file, dynamic link libraries, and device driver be referenced from the
 CONFIG.SYS file.  These functions are only performed by the Setup program.
 Refer to the CPU Monitor Plus User's Guide for more information.

 To permanently unload CPU Monitor Plus from your system, select the UnInstall
 menu item from the File menu.  The Un-Installation process will be complete
 after the computer has been restarted.  CPU Monitor Plus may be reinstalled
 later at your convenience.


ΓòÉΓòÉΓòÉ <hidden> Installation Error Help ΓòÉΓòÉΓòÉ

CPU Monitor Plus was unable to complete the installation process.  If you press
OK to continue, not all CPU Monitor Plus functions will be available.


ΓòÉΓòÉΓòÉ <hidden> Installation Error Help ΓòÉΓòÉΓòÉ

CPU Monitor Plus was unable to backup the system OS2.INI file.  Since CPU
Monitor Plus makes changes to OS2.INI, it first makes a backup copy called
OS2INI.BA.  This backup file is put in the same directory where OS2.INI is
found.

At this point, you may still continue installing CPU Monitor Plus.  However, in
the very unlikely event that the OS2.INI file becomes corrupt, CPU Monitor Plus
will not have created the OS2INI.BA backup.

Select YES to continue with the installation process.  Select NO to abort the
installation.

startup information.  UnInstall does not update the CONFIG.SYS file. After
Un-Installing, CPU Monitor Plus will be completely removed once the computer
has been restarted.

Note:  Part of the installation process requires that the CPU Monitor Plus
device driver, dynamic link libraries, and help file be referenced from the
CONFIG.SYS file.  These references are not removed by UnInstall.  Refer to the
CPU Monitor Plus User's Guide for more information.

CPU Monitor Plus may be installed later at your convenience.

ΓòÉΓòÉΓòÉ 11. Command Line Switches ΓòÉΓòÉΓòÉ

The following command line switches are available:

 o /START=<fname>
 o /LOG=<fname>
 o /FREQUENCY=<seconds>

 For /START, <fname> is the name of a file containing the program names to be
 started.

 For /LOG, <fname> is the name of the file where logging information will be
 written.

 For /FREQUENCY, <seconds> is the number of seconds (1 to 60) between screen
 updates.

 Note:  No spaces are allowed between the equals sign ('=') and the value in a
 command line switch.  Spaces are required between each command line parameter.

  Example:
    CPUMONP /FREQUENCY=5 /LOG=C:\mylog.log /START=C:\bastart.ba
 will do the following:

 o Sets the initial display frequency to 5 seconds;
 o Enables file logging to the file C:\MYLOG.LOG;
 o Starts the programs as specified in the file C:\START.BA.

 Once CPU Monitor Plus is running, data logging may be changed by selecting the
 Log menu item; Additional programs may be started via the Start menu item; The
 display frequency may be changed via the Configure menu item.

 See the CPU Monitor Plus User's Guide for more details on using the command
 line switches.
