Created March 23, 2012 02:43
A very simple script to merge multiple RRD files, since none of those available seem to work.
#!/usr/bin/env python
"""Simple script to merge multiple RRD files together.
Accepts any number of RRD file names as arguments. Produces an "rrdtool dump"
style file on stdout. The last RRD file should have a slot for every possible
record in the resulting merged RRD.
Run something like:
$ python simple-merge-rrd.py filea.rrd fileb.rrd filec.rrd | \
