I came across the permissions issue as well when I played around with it. You can set the permissions on the socket, but you need to put those arguments (-P <perm> -s <group>) before you specify the socket.

However, if you are integrating any other RRD source (e.g smokeping), then you will also need to make that rrdcached aware as well because observium will only look at rrdcached for its rrd’s if you enable rrdcached. I couldn’t find any integration support for rrdcached in smokeping, but I don’t think it should be hard to add since it all goes via the rrdtool perl module.

There was some discussion on IRC the other day about rrdcached and how it can be used with Observium to reduce your storage IO a lot when polling a huge amount of interfaces.

However, not a lot of documentation exists yet on how to get rrdcached to work with observium. I did some trial and error and found a working method and wrote a quick and dirty guide.

You can find it here: http://blog.best-practice.se/2014/10/using-rrdcached-with-observium.html

Feedback is highly appreciated!
