Re: grapher

during the installation I created following directories, in /usr/lib/cricket

config cricket cricket-data public_html

and here is cricket-conf.pl entries :

$gCricketHome = "/usr/lib/cricket";
$gInstallRoot = "$gCricketHome/cricket";
$gConfigRoot = "$gCricketHome/config";


now I am thinking may be grapher.cgi is not able to find the rrd files
and that is the reason png files can not be created in /tmp/cricket-cache/

do you think I should change any thing in grapher.cgi ?


Thanks
