I have worked my way through the tutorials and experimented a little, and things are going fine. I am happy to have found this tool, because it does exactly what I want.</div><div><br></div><div>However, I will need to occasionally add (or remove) variables to an existing rrd, and hence to the rra's.</div><div><br></div><div>How is this done? </div><div><br></div><div>I have found, in the archives, some old suggestions that I might unload the database, and reload it. Is this still the way to do it, and if so, can you point me to detailed instructions?</div><div><br></div><div><br></div><div>With kind regards, and thank you for your attention,</div><div><br></div><div><br></div><div>Michel</div></div></body></html>
