i am running this version
it appears (to me) that it writes that specific RRD you are looking at so
there is no delay in the data
[i am actually running 4.2.0 with only the 3 files changed in the beta
version, which includes that hobbitgraph.cgi]

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
