I just for the first time attempted to install Cacti from the RPMForge repo on CentOS 4.4.
And I have to say that it hasn't gone very well at all. I have installed Cacti on Fedora a good 20 times with absolutely no problem.
Basically the default rrds/graphs for localhost are generated but no other rrds/graphs are generated.
When I look at the poller cache or snmp cache I see all the data. When I turn on Graph Debugging I get the following:
RRDTool Command:
/usr/bin/rrdtool graph - \ --imgformat=PNG \ --start=-86400 \ --end=-300 \ --title="DCN2948-1 - Traffic - Fa10" \ --rigid \ --base=1000 \ --height=120 \ --width=500 \ --alt-autoscale-max \ --lower-limit=0 \ --vertical-label="bits per second" \ --slope-mode \ DEF:a="/var/www/cacti/rra/dcn29481_traffic_in_19.rrd":traffic_in:AVERAGE \ DEF:b="/var/www/cacti/rra/dcn29481_traffic_in_19.rrd":traffic_out:AVERAGE \ CDEF:cdefa=a,8,* \ CDEF:cdefe=b,8,* \ AREA:cdefa#00CF00:"Inbound" \ GPRINT:cdefa:LAST:" Current:%8.2lf %s" \ GPRINT:cdefa:AVERAGE:"Average:%8.2lf %s" \ GPRINT:cdefa:MAX:"Maximum:%8.2lf %s\n" \ LINE1:cdefe#002A97:"Outbound" \ GPRINT:cdefe:LAST:"Current:%8.2lf %s" \ GPRINT:cdefe:AVERAGE:"Average:%8.2lf %s" \ GPRINT:cdefe:MAX:"Maximum:%8.2lf %s"
RRDTool Says:
ERROR: opening '/var/www/cacti/rra/dcn29481_traffic_in_19.rrd': No such file or directory
When I turn on debug I get the following in the logs (I have added logging for poller.php):
poller.log

It doesn't appear to do anything at all. I have also tried installing using the tgz from the cacti.net website with no success. I think the problem is being caused by one of the depenedencies, probably php. The bigest difference between the CentOS install and Fedora in reference to Cacti is the version of php. Centos as you know uses php4 and Fedora uses php5.
And yes I have followed the documentation that resides on the CentOS wiki as well as the docs on the Cacti website.
I have also tried running the poller as root with no success.
Any help would be greatly appreciated.
