rrd files in the directory "/var/lib/ntop/rrd/interfaces".
cacti is working as its graphing CPU, memory, my snmp router etc etc.
So I setup a new datasource called ipBytes pointing to /var/lib/ntop/rrd/interfaces/eth0/ipBytes.rrd with no Data input (doesn't need a script as ntop is writing the rrd file directly).
I setup the graph using the ipBytes datasource, setup the graph hierachy to display it.
The problem is that cacti just refuses to display a graph for me
the RRD file is there, is updating, and has the correct permissions, but cacti just isn't reading it
have I missed anything obvious ?
Cheers
