- IPRATES.CMD 1 July 1996
-
- What It Is:
- Graphical display of the TCP/IP connection showing:
- o Momentary and overall data receive rate
- o Percent utilization (active time/total time)
- o Momentary and overall data send rate
-
- Requires:
- TCP/IP and VREXX (HOBBES - os2/ibm/ews/vrexx2.zip)
-
- Parameters:
- Single, numeric, value representing the amount of time
- (seconds) to wait between TCP/IP poll operations. Missing or
- invalid(character) values result in default wait of 10
- seconds.
-
- How To Install:
- Copy IPRATES.CMD to the CMDs directory listed in your PATH.
- (You do have a CMDs directory, don't you?) Create a program
- object which refers to IPRATES.CMD.
-
- I've set the parameters to: [Wait] 1
- which will prompt for a wait time. If I click on OKAY without
- entering a value then IPRATES will wait >1 second between poll
- operations.
-
- Other program object settings you may want to set are:
- [Session] (check) Start minimized
- (uncheck) Close window on exit
- [Window] (radio) Display existing window - !required!
- [General] Assign any personally pleasing title
- Create/assign/find/modify any convenient icon
-
- Warnings, Comments, Caveats:
- [Window] (radio) Display existing window - !required!
- This is important. VREXX does not operate well when there are
- more than one(1) process using it at the same time. Not sure
- why.
-
- The display window is sized and positioned to occupy the
- upper-left 1/16th corner of the desktop window. It may be
- resized and moved while running but, the new size and position
- are not remembered between invocations. Again, VREXX does not
- return data to the REXX program about the window's position.
-
- Several operational parameters (including window position and
- size) can be permanently changed by editing IPRATES.CMD.
-
- BackGround = 'BLACK' /* window background */
-
- win_pos.top = 100 /* position of 100+---+ */
- win_pos.bottom = 75 /* window as | | */
- win_pos.left = 0 /* percent of 0+---+ */
- win_pos.right = 25 /* maximum extents 0 100 */
-
- np = 50 /* number of points to draw */
-
- recv.0 = "GREEN" /* colors with which to draw */
- rovr.0 = "CYAN" /* the lines of the graph */
- util.0 = "YELLOW" /* VREXX supports color choices */
- send.0 = "RED" /* BLACK WHITE RED GREEN */
- sovr.0 = "PINK" /* BLUE CYAN YELLOW PINK */
-
- IPRATES must be started AFTER the TCP/IP connection has been
- established. IPRATES may be terminated with Ctrl-Break in the
- (minimized) command window. When IPRATES is stopped or the
- TCP/IP connection is broken the command window displays final
- statistics then waits for a keyboard entry. The graph window
- will not be dismissed until the keyboard entry is received.
-
- Modifications:
- 28 June 1996 - initial release - worked okay but needed
- something
-
- 29 June 1996 - added the something missing. prior version
- would redraw the graph all over from the beginning on a
- redraw; (REXX meta-file?) This version clears and redraws
- the display window for each poll interval. Strangely
- enough, this was much more pleasing.
-
- 1 July 1996 - Final iteration - "production version" - 29 June
- did not rescale the "overall" graph when a new maximum was
- set. Also, added axes to the graphs. Receive rate marks
- the maximum with a vertical line; send rate marks the
- minimum (0 bytes/sec) with a vertical line. Together,
- they mark the utilization graph. Removed some commented
- instructions.
