RRDtool: Graphing the DRBD sync rate with RRDtool

This little AWK program converts a series of DRBD's /proc/drbd output into a file that can be loaded into a RRD database. As a result you can see the throughput of all your ressources over time, how they affected each other, and which syncer rate combinations are the most effective.

Color improvements welcome ;-)

You have to "rrdtool create" the database with the --start parameter. Otherwise RRD will refuse to fill the database with entries older than the date of creation!
