Hi, but I am able to create graph by using this procedure
bash$ cd /var/lib/ganglia/rrds/__SummaryInfo__/
> bash$ rrdtool graph /tmp/foo.png --end now --start end-120000s \ > > --width 400 DEF:myline=cpu_nice.rrd:sum:AVERAGE \ > > LINE1:myline#0000FF:"foo\n" > bash$ file /tmp/foo.png
and the error i am getting in /var/log/httpd/error_log while i am opening ganglia page and select the node in the web page On 7/18/06, Ramon Bastiaans <[EMAIL PROTECTED]> wrote:
This means that rrdtool is actually not working, if you read the error printed by rrdtool. Also it seems it is still using /usr/bin/rrdtool instead of you alternate path in usr/local. Check your config again. rrdtool complains about not having permission to load it's library.. Maybe a wild idea is to check the permissions on that file it prints?? (the error message already suggests this!) Also the undefined function means that you do not have GD and/or the php-gd module installed. - Ramon. toney samuel wrote: > Hi Ben, > > I have tried as per your advise and rrdtool is working properly.
