Client and server are both CentOS 5.8, x86_64, vm under ESX 5.1
Observium is latest from SVN -- 3581
Client is running check_mk-agent-1.2.0p4-1, and munin-node-2.0.10-1.el5
Description
When installing the munin-node, it comes with several pre-defined scripts which take advantage of features added to munin as of version 1.3.3. They added support for graph types which are not supported by rrdtool – AREASTACK, and LINESTACK
{1,2,3}. These are magical types which get converted to AREA or LINE{1,2,3} for the first, and subsequently STACK for the rest of the entries.

The server-side observium munin interfacing code does not perform this translation and rrdtool complains about unrecognized graph types.
Additionally, when those scripts define cdefs, the way those values are passed on to rrdtool also results in errors.
I have addressed both issues in the attached patch of html/includes/graphs/munin/graph.inc.php
