Hello Siddarth,
You can enable MapServer debugging by setting DEBUG ON in the .map
file for the MAP, LAYER and CLASS objects you want to debug and adding
a LOG parameter in the WEB object pointing to a file where the log
info will be stored (you can use abdolute or relative paths, this file
needs write access for the IUSR).
See also:
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?DebuggingMapserver
http://mapserver.gis.umn.edu/doc44/mapfile-reference.html (serach for
DEBUG and LOG)
Now you will get a log file with MapServer log info.
Another handy tool to monitor running programs is filemon from
www.sysinternals.com
Install it and run it and don't forget to use a filter on the name of
your MapServer executable or you will have to dig to giant loads of
log info (sometimes necessary though to not use a filter).
Regards,
Emil
