Changes
→munin plugin
at /etc/munin/plugin-conf.d/ somewhere.
Extended Version for old system using user_beancounter.
Put it with the munin plugins and make a link for every
graph which should be produced named like:
vebc_VALUENAME1_VALUENAME2_..._VEID
e.g.: vebc_numflock_numpty_numsiginfo_101

This is not too performant but should do and the graphs are much
more readable then the first solution.
