====== Log Monitor Version 3 ======
The new version of the log monitor works as a GUI and as a text-based interface, allowing you to monitor a telescope from a terminal window. It also now keeps a text log of its output, will take the telescope name and input log on the command line and has a few other bug fixes.

The first step is to make sure eRemoteCtrl is recording a log, or that you've started Dave's stream_log script. If you want to use the eRemoteCtrl log but don't know it's name, try <code>ls -lrt /vlbobs/ivs/logs | tail -20</code> and look for a likely named file.

Usage:<code>pcfs_log_monitor_test.pl [-a <antenna ID [Hb|Ho|Ke|Yg|Ht]>] [-n (no GUI)] [-f <log file name>] [-p <path to file (default /vlbobs/ivs/logs/)>]
</code>

  * Specifying ''-n'' will start it in the text-based mode
     * Note: this was causing a bug where any file path specified other than ''/vlbobs/ivs/log/'' would result in an error message and program exit. Since I wanted to run this on (e.g.,) ''/tmp/ke.log'' I modified the script to allow an optional argument for the path ''-p'' which defaults to ''/vlbobs/ivs/log/''. 
     * usage would now be for a file in ''/vlbobs/ivs/logs/'' <code>pcfs_log_monitor_test.pl -n -a ke -f r1234ke_erc.log</code> as before, but for a file in (e.g.,) ''/tmp/'' <code>pcfs_log_monitor_test.pl -n -a ke -f ke.log -p /tmp/</code>
  * The log file name can be specified with a full path but if you just give the file name, the program will look for it in ''/vlbobs/ivs/logs/''

For example:
<code>pcfs_log_monitor_test.pl -n -a Ke -f r1234ke_erc.log</code>
This will start it in text-based mode for Katherine, opening the log file ''r1234ke_erc.log''.

The GUI version looks very similar to before. The ASCII version mimics the GUI a bit. Alarms or warnings are announced with a beep and the last alarm or warning is repeated in the small blue rectangle near the top. There are a few keyboard shortcuts to do useful things:
  * Q = quit
  * T = turn on/off text messaging when there's an alarm
  * W = configure watchdog timer
  * D = set the disk offset
  * A = acknowledge an alarm
