Hello Tobi,

we don´t want to have the states inside of the RRD. For these we work with
thresholds outside of it.

What we want is a value, what we can give to the RRD with an update-command,
so the RRD knows that here was a real breakdown and it should not backfill
here. You mentioned in your first post that we should set the mrhb very
small, that the graph will break when only one check couldn´t get
performanca-data. 
At first we thought that this could solve our problem.
But in my second post you can see a couple of reasons why we couldn´t do it
like that. Because when there is for e.g. a system-latency and the data
would come in some seconds too late, the graph will show a break, where
actually no break was. 


Cheers!
