Hi,

As always kudos Henrik for the excellent work.

I didn't start do play with the new hobbit beta version, who good
improvements about the disk I/O limitations on huge load systems. I have a
specific question about what's hobbit behavior when disk cache for rrd is
active, and i request the graph for a specific metric. Will i not see the
last (around) 30 minutes of info on the graph? Or is there some kind "trap"
activated when i request a specific graph, who'll request that the info for
that host/service should be written to the RRD before the graph is
generated?

Regards
Werner
