It should log to cgierror.log in the Hobbit log directory, but you 
probably have to create this file and make it writable by the userid
that your CGI scripts run with (probably "nobody" or "httpd" - see what
userid's appear for your httpd processes).

No, it really does need the environment settings provided by the
webserver CGI interface.

The URL for one of these graphs looks like

http://www.hswn.dk/hobbit-cgi/hobbitgraph.sh?host=voodoo.hswn.dk&service=la&graph_width=576&graph_height=120&disp=voodoo%2ehswn%2edk&nostale&graph=hourly&action=view


To run the hobbitgraph CGI by hand, you would do

REQUEST_URI="" 
QUERY_STRING="host=voodoo.hswn.dk&service=la&graph_width=576&graph_height=120&disp=voodoo.hswn.dk&nostale&graph=hourly&action=view" 
/usr/lib/hobbit/cgi-bin/hobbitgraph.sh >/tmp/cgi.out

i.e. provide an empty REQUEST_URI and a QUERY_STRING with the part of
the URL after the "?".


Regards,
Henrik
