This monitor program puts a small icon in your Window's systray. The icon changes depending upon the state of Level 3, and when exceptional things happen it will put up a balloon for a short while. You can see the black square for the rate meter (no beam at this moment) and the green lights indicating no missing events!

The program does almost all of its work in JScript (JavaScript), so it is very easy to extend.

Installation

This program requires a relatively advanced version of the Microsoft Scripting system installed. I am not confident this will run on NT4 (not tested, but the program does use advanced features of the shell).  The following steps must be taken to use it:

1. Install 5.5 or better of the Windows Scripting Host. The downloader is on the download page (natch), and if that isn't available, you can look for a more recent release on the top level page (an up-to-date Win 2000 or XP system won't need to do this).
   • Not well tested on Win 98 or ME. Please, let me know how it goes if you try it.
2. If you are running NT4 or an older version of W2K (no service packs) you may have to upgrade the installer service. I recommend just trying to install the program and see if you get an installer version error. If you do, then download and install the below file.
   • Windows Installer Version 2
3. Install the L3 Monitor. The install file is about 1 megabyte big. After you have it on your system, just double click it.
   • Installation File (1mb)
4. The first time you need to run L3 Monitor yourself (look in the start menu). After that it will start when you log in.

Versions

• Version 2.1.1 released 2/22/03
  • Uses new monitor information source.
• Version 2.1.0 released 3/31/02
  • If luminosity isn't present, don't display it and don't not display other information.
  • Fixed some bugs in how the Sound Muted menu item was handled.
• Version 2.0.1 released 3/26/02
  • Bug prevented open of URLs fixed (duh)
  • Built in release mode instead of debug mode
• Version 2.0.0 released 3/26/02
  • Can switch between DAQ1 and DAQ2 for rate information (DAQ2 isn't complete yet; still waiting on farm node information in the XML).
  • Has TeV stack, luminosity, and store number (store number is not always accurate for technical reasons).
  • Can turn off auto scaling for rate.
  • Can turn off pop-ups when the scaling changes (when it is on).
  • Changed default URLS.
  • Infrastructure changes for those wishing to modify the jscript that runs this (you can add options, add urls, etc.).
  • Will now check for new versions.
  • Fixes to make it run better on portables and other things that constantly disconnect and reconnect to the 'net.
• Version 1.3.1 released on 11/02/01
  • Correctly deals with the segment bridge sending an empty (but present) current_rate and current_miss_rate node in the xml.
  • If the rate is higher than any defined scale, won't get a array index JavaScript error.
• Version 1.3.0 released on 10/26/01
  • Correctly deals with any number of segment bridges (except zero!).
  • Uses the rate information calculated by the segment bridge program directly, rather than calculating it from the total number of events
  • When the Supervisor is communicating with L3 clients, a "S" will appear in the systray and the mouse-over tool tip will list the machines it is trying to talk to.
• Version 1.2.0 released on 9/07/01
  • Fixed how the Internet is opened (not clear how this works from docs). Should make it so the thing works much getter on laptops, and eliminate the once-per-day stall that Andy reported.
  • Figured out how to do an "upgrade" install. Sadly, I totally messed up teh installer in the process. You will have to uninstall the current version and install this one. After that, you will be able to install things on top of each other.
• Version 1.1.0 released on 8/29/01
  • Plays sounds (you can mute it).
  • Won't ask your portable to connect to the net if it isn't already connected.
  • Can print out log files
  • Better management of the meter scale
• Version 1.0.0 released on 8/23/01

Use

Usage is simple -- there is very little you can do to interact with this program, so it is easy to use!

• In general, to find out what is going on, move your mouse over the icon. It will give you a very short summary.
• When L3 is taking data, the display is usually a meter with two dots. If all is well, both are green (actually, the lower dot isn't hooked up to anything yet). If the upper dot goes yellow, then there are some incomplete events, if the upper dot is red, then most of the events taken over the past 10 seconds or so had missing crates. The tool tip will give you actual rates.
• Several menu items are quickly accessible by right-clicking on the icon.

I'd give you a screen shot, but don't have that on this computer!
