Copyright ©1993, 1994 Scott Hess All Rights Reserved. Welcome to TimeMon3.2 TimeMon gives a graphical representation of where the CPU cycles are going. It's coarse, but better than nothing. TimeMon3.2 requires NeXTSTEP3.0 or better, and can run on NeXT, Intel, and HP PA-RISC hardware. TimeMon3.2 made minor updates in the source code, and fixed a bug with the lagFactor which caused the inner ring to work incorrectly. Also, the ability to use separate sets of defaults for color and monochrome machines was added. TimeMon3.1 added color support and fixed a significant bug in previous versions' calculation of the CPU average times. See the README.BUGFIX that comes with the source code. Amazingly enough, the buggy version came up with almost the same results, even though it was incorrect. Sigh. TimeMon3.1 also does a hide when autolaunched, so that it doesn't aquire focus when you login. What Am I Seeing? There are three general usages of CPU time under Unix. System time is that time spent within the kernel. User time is that time spent executing a user's programs, but not within the kernel. Nice time is user time that has been set to a low priority. There is also one other type of CPU time ± idle time. This is time during which there is no productive work to do, so your machine essentially twiddles its thumbs at a high speed. Lucky enough, the NeXT supplies four ``colors'', which maps well to the four types of timing information. Black is for system time, dark gray for user, light gray for nice, and white for idle time. You can change these colors using the ``wells'' at the top of this panel. TimeMon displays this information within the program's icon. There are three rings displayed. The innermost ring is updated according to the Update Period, which specifies the number of seconds between updates, and Lag Time which specifies how many update periods should be averaged together for the innermost ring. The middle ring is an average of the last Layer Factor update periods, and the outer ring is an average of the values over the course of the square of the Layer Factor update periods. The values in the fields are automagically stored in the user's defaults database. The difference between Lag Time and Layer Factor are subtle but useful. Both values cause the program to average information over some period of execution, resulting in a more stable display. Lag Time should give a short amount of time useful to even out the ``bumps'' on the innermost ring. A Lag Time of zero can result in a very dynamic display. A similar effect could be achieved by increasing the Update Period. TimeMon has been extensively tuned to use as few CPU cycles as possible. But, if you feel the need to pause it, click the Pause menu item. Otherwise, adjust your Update Period to a higher value so that it updates less often Other Very Important Information Here we get into a blatant advert. While I'm not writing TimeMon, I spend some of my time developing shareware programs, and some of my time doing custom programming for random clients (or is that random programming for custom clients?). http://www.winternet.com/~shess/ is my WWW home page and contains links to the following packages. One program which I've been developing and distributing is a vt100 terminal emulator named Stuart. Stuart is extremely similar to Terminal under NeXTSTEP2.0 and 3.0 ± check Terminal's Info panel to see why. I've added nearly a billion features to Stuart, though. As of December 1994, Stuart2.4 is still the latest released version. You can download Stuart from the archive site sonata.cc.purdue.edu under the directory /pub/next/2.0-release/demos, filename Stuart2.4.tar.Z. There are newer unreleased versions of Stuart on the archive site ftp.winternet.com under /users/shess. These versions include Intel and HPPA support. Another package of mine is TickleServices. TickleServices is a NeXTSTEP Services menu framework. It includes a scripting language which can be used to write services, and a slew of ``example'' services, some of which are worth the registration price on their own. The latest version is TickleServices1.11, which includes support for NeXT, Intel, and HPPA. TickleServices1.11.tar.gz is available on ftp.cs.orst.edu under /software/NeXT/demos/programming. If you cannot use anonymous ftp from your site, feel free to contact me. Likewise, if you need versions of these programs for new hardware or old operating systems, let me know.
