RepServer Errorlog checker
From SybaseWiki
The script below is for monitoring the repserver errorlog - it works with any version of repserver and does not need to write to the errorlog itself in order to monitor it. However, since it doesn't write to the errorlog, it does need a $ADMINDIR/control_files/ directory which you may wish to create as a non-transient file (rserrlogmarker.dat) is maintained there. Also, as per the script notes, you can easily modify this script to monitor *any* log; be sure to give rserrlogmarker.dat and the other files in the config section different names or keep them elsewhere so that there is no conflict.
