Hello,
I'm going to be changing the RRA's in my cluster to retain more granular
data for a longer period of time. From what I understand, I need to erase
the current RRD's and let gmetad create new ones. I'd still like for users
to be able to view the archived metrics for a period of time, however. Can
I copy off the current RRD's to a different directory, or even a different
web server and let Ganglia run in an offline mode? This would strictly be
for looking at the old data, not gathering the new metrics. I've read that
there's a way to export/import the data from my current RRD's into the new
ones, but that process looked pretty ugly.
Thanks!
Dave
