Re: [Observium] Reduce your storage IO with rrdcached

FWIW, I just looked through this quickly and wanted to recommend changing item 3 to edit options in /etc/default/rrdcached. Testing this now.... thanks for writing that up!

Thank you Milton, you were right, setting the -s flag before -l solves the whole problem. Updated the blogpost! /Markus

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.
