- ΓòÉΓòÉΓòÉ 1. General Help ΓòÉΓòÉΓòÉ
-
- General Pegasus Help
-
- Pegasus (The Greek Myth) A winged horse that with a stroke of his hoof caused
- the fountain Hippocrene to spring forth from Mount Helicon.
-
- Pegasus Resource Monitor (The Product) A 32 bit application that with a click
- of a mouse causes a fountain of performance statistics to spring forth from
- Mount OS/2 2.x!
-
- Unlike other OS/2 system monitors, the measurements in Pegasus come directly
- from the operating system. This provides accurate measurement data as opposed
- to 'approximated' information found in other monitor systems.
-
- In addition, Pegasus can be upgraded to the C.O.L. Systems Inc. network
- performance and capacity management tool Osrm2 Version 2.0. As a matter of
- fact, Osrm2 uses the same data collection as Pegasus
-

- counts, are displayed in pages. A page represents 4,096 bytes of memory.
-
- The Paging metrics contain:
-
- o PageIn Count - The number of pages swapped in from the swapper.dat file.
-
- o Page Faults - The number of times a page 'miss' occured. This is denoted as

-
- This option can be used if Pegasus detects that Theseus/2 is installed on your
- system and you want to run a working set analysis.
-
- Working set analysis allows you to determine how much memory a particular
- application is using over time.
-
-
- ΓòÉΓòÉΓòÉ 5.7. Help For Application Kill ΓòÉΓòÉΓòÉ
-
- Application Kill
-
- Although a brutal term for it, in the rare occasion a runaway process must be
- stopped, or it is convenient to stop a process from Pegasus, this option will
- send a kill signal to the selected process.
-
- If the target process has a signal handler that chooses to ignore the kill
- signal, this option will not always work.
-
-
- ΓòÉΓòÉΓòÉ 6. Help For I/O Activity ΓòÉΓòÉΓòÉ
-
- I/O Activity

- is available for use on the logical disk.
-
- For Communication Ports, the metrics are the same as those for Logical disk
- except there are no storage metrics.
-
- For Printers, the metrics are the same as those for Communication Ports except
- there are no Read Event metrics.
-
-
- ΓòÉΓòÉΓòÉ 7. Help For Configuration Options ΓòÉΓòÉΓòÉ
-
- Pegasus Settings
-

- item from the Help Manager's Options action.
-
- Note: All changes, with the exception of the Auto-Start options, take effect
- immediatley.
-
-
- ΓòÉΓòÉΓòÉ 7.1. Help For Window Position Save ΓòÉΓòÉΓòÉ
-
- Save Window Positions
-
- This option, when set, will cause Pegasus to save the last known positions of
- the active tables and graphs.
-
- When Pegasus is run again, all windows that are set for automatic open will
- re-appear in their last position. If not set for automatic open, the windows
- will appear in their last position when started from the View menu option.
-
-
- ΓòÉΓòÉΓòÉ 7.2. Help For Process ID in hex ΓòÉΓòÉΓòÉ
-
- Display Process ID in hexadecimal
-
- When this option is set, Pegasus will display the process id (PID) in
- hexadecimal instead of decimal.
-
- The hexadecimal display shows a 4 digit number. For example:
-
- The hexadecimal process id of : 0FD3
-
- converts to (0x4096)+(15x256)+(13x16)+3 = 4051.
-
-
- ΓòÉΓòÉΓòÉ 7.3. Help For System View Auto Start ΓòÉΓòÉΓòÉ
-
- Auto Start Options
-
- Pegasus can automatically open the system resource monitor table when started.
-
- The system resource table is still available after startup from the Views
- action bar.
-
-
- ΓòÉΓòÉΓòÉ 7.4. Help For I/O Display Auto Start ΓòÉΓòÉΓòÉ
-

- The I/O activity table is still available after startup from the Views action
- bar.
-
-
- ΓòÉΓòÉΓòÉ 7.5. Help For Application View Auto Start ΓòÉΓòÉΓòÉ
-
- Auto Start Options
-
- Pegasus can automatically open the Application resource table when started.
-
- The Application resource table is still available after startup from the Views

-
- Swap Percent Warning
-
- This control determines when Pegasus should change the color of the Swap
- activity bar to red in the Mini-Monitor.
-
- Swap percent is that percentage of available space used by swapper.dat. The
- higher the value the less free space remains.
-
- Setting this to 0 will turn off color changes.
-
-
- ΓòÉΓòÉΓòÉ 7.12. Help For Settings Reset ΓòÉΓòÉΓòÉ
-
- Settings Reset

- ΓòÉΓòÉΓòÉ 8. Help For Pegasus Mini Monitor ΓòÉΓòÉΓòÉ
-
- Pegasus Mini-Monitor
-
- The Mini-Monitor displays bar graphs for the following resources:
-
- o CPU Busy - The bar measures the percent CPU busy from 0 to 100%.
-
- o RAM Used - The bar measures the percent of total Physical (BLUE/RED) memory
- in use and the percent of Resident memory (GREEN).
-
- o Swap Used - The bar measures the percent of available space (BLUE/RED)
- consumed by swapper.dat and the percent that was originally allocated at boot
- time (GREEN).
-
- You can set when the bar color changes from blue to red (warning) from the
- Options->Configuration Dialog.
-
- Exception Log
-
- The Mini-Monitor maintains an exception log. This log can be displayed by
- double clicking on the client area of the Mini-Monitor with the Right Mouse
- Button.
-
-
- ΓòÉΓòÉΓòÉ 9. Help For Exception Log ΓòÉΓòÉΓòÉ
-
- Exception Log
-
- The Exception Log contains a list of exceptions that have been generated based
- on the warning thresholds as set in the Options->Configuration dialog.
-
- Exceptions are list by:
-
- 1. Time Stamp
-
- 2. Type ( Cpu, Ram, Swap )
-
- 3. Threshold Exceeded ( set in Configuration )
-
- 4. Current Value
-
- The list is added at the top, this way the most recent exceptions will be
- displayed.
-
- To save the data to an ascii text file, select the Save button. You will be
- prompted for a file name.
-
- Once the exceptions have been viewed or saved, you can clear the list by
- clicking on the Clear button.
-
- CAUTION:
- If there are a large number of exceptions and you do not clear them out from
- time to time Pegasus will begin to discard the messages.
-
-
- ΓòÉΓòÉΓòÉ 10. Help For Working Set Dialog ΓòÉΓòÉΓòÉ
-
- General
-
- This dialog allows you to track a single applications working set.
-
- A working set is defined as the amount of memory references over a period of
- time (working set interval) by the application.
-
- Note: Working set interval and sample rate are not the same. The working set
- interval is how many time tics qualify a memory page as part of the working
- set. The sample rate is how often do you want to update the display with this
- information.
-
- After setting the Working Set Interval and the Sample rate, and clicking the
- Start button, the display will begin to update the following:
-
- o Date-Time The date and time stamp of the Sample.
-
- o Now(k) The amount of memory accessed at the time of the Sample.
-
- o WS(k) The amount of memory found to be accessed within the Working Set
- Interval specified.
-
- o Accessed(k)
-
- Note: 1 k = 1024 bytes.
-
-
- ΓòÉΓòÉΓòÉ 10.1. Help For WS Interval ΓòÉΓòÉΓòÉ
-
- Working Set Interval
-
- In short, the working set interval determines the number of memory pages
- referenced over a period of time. For example, if you set this value to 3, the
- working set analysis will see how many pages have been referenced within the
- last 3 timer tics intervals.
-
- Use the Sample Rate to set how often you want the display updated.
-
-
- ΓòÉΓòÉΓòÉ 10.2. Help For Working Set Sample Rate ΓòÉΓòÉΓòÉ
-
- Working Set Sample Rate
-
- The working set sample rate determines how often the screen is updated with the
- analysis data. Each new sample is placed at the top of the screen to avoid
- scrolling.
-
- Use the Working Set Interval to set how many intervals should be considered in
- the working set analysis.
-
-
- ΓòÉΓòÉΓòÉ 11. Help For Process Memory Dialog ΓòÉΓòÉΓòÉ
-
- Process Memory
-
- This dialog displays per process memory usage information. A snapshot taken
- when the dialog is invoked and the user is warned that the dynamics of memory
- ownership are likely to change the values once the snapshot is taken.
-
- For each process in the system, the following information is provided:
-
- 1. Process Name
-
- 2. Process ID
-
- 3. Private Memory The amount of memory, in kilobytes, in the private arena of
- this process. If there are more than one process that has a map to this
- private page, the process with the lowest process id (PID) is charged with
- ownership.
-
- 4. Shared Memory The amount of memory, in kilobytes, from the shared arena
- owned by this process.
