Add ds rra.pl
http://gigo.com/ftp/pub/src/add_ds_rra.pl
used for .rrd files (www.rrdtool.org) to add new DS’s or RRA’s to existing files quickly without resorting to rrdtool dump | filter | rrdtool restore.
This crappy peice of shit script will work on sparc sol 7. For others, you WILL have to edit it. The details in a .rrd file just don’t exist to automatically figure out appropriate byte and bit padding for the structures involved; and in reality, the functionality of this script is better put into rrdtool itself.
If you get this working for other platforms, I’d appreciate being able to post about it here.
