I'm trying to figure out the best way to use rrdcached on a single server for multiple graphing tools. Currently I'm using cacti, observium and collectd on the same server (running CentOS 6.7) that all use rrdtool to create graphs. While following a guide I found (http://blog.best-practice.se/2014/10/using-rrdcached-with-observium.html) which works fine for just Observium I get all my graphs for cacti or collectd messed up since I define the folder with -B to my Observium RRD folder.
Any tips from people in the same situation or do I have to split up my monitoring tools between servers (which seems to be a huge waste of resources)?
