[munin-users] Small utility to move data from one RRD to another

[Steve S. <ste...@pw...>]

One annoying thing about Munin is that you might have a brand new RRD file if
- you change some config of the plugin
- you want to change the archive precision of the RRAs.

So I cooked up a small utility rrdmove[1] that can copy data from one
RRD to another. I used it for my own purpose, but I'm relasing it
publicly in case someone is interested.

The usage interface is very rough, but simple:

rrdmove src.rrd dst.rrd

It will copy all the DS data in src.rrd into dst.rrd, so you have to
create the dst.rrd clevery.
The data will be averaged with RRD in order to be able to
transparently resample it.
