<div>Ahh, right!</div><div><br></div><div>Whereas that here, for now, it will be implemented only on new RRD, I can determinate RRA:HWPREDICT as pre-requisite. So if this plugin work properly, I can try to develop a script to do what you suggested in the old RRDs.</div>

Rrdtool tune can tune the various HW settings, but not actually add the new RRAs (sorry, I was a bit unclear there)</span></p>
