[LONG!!!]Nagios+apan on Mandrake9.1 and ... PITA

[Fredrik Wänglund]

1) The icond should show up next to the service-name in the 
webinterface. Look at the screenshots
at apan.sf.net.


2) The RRD-file should be readable by the web-server user. The cgi 
should write some info
to apancgi.debug. Look in that file and see if you can find any possible 
errors.

Maybe you can send me the relevant lines from apan.debug, apancgi.debug, 
apan.cfg, your service-definition and
the command you used to create the RRD-file?
