<div dir="ltr"><div>Hi,</div><div><br></div><div>As per the URL <a href="http://oss.oetiker.ch/rrdtool/tut/rrd-beginners.en.html">http://oss.oetiker.ch/rrdtool/tut/rrd-beginners.en.html</a> I am not sure i understand about </div>
<div><br></div><div>In case of linear databases, new data gets appended at the bottom of the database table. Thus its size keeps on increasing, whereas the size of an RRDtool database is determined at creation time. Imagine an RRDtool database as the perimeter of a circle. Data is added along the perimeter. When new data reaches the starting point, it <b>overwrites existing data.</b> This way, the size of an RRDtool database always remains constant. The name "Round Robin" stems from this behavior. </div>
<div><br></div><div>"When new data reaches the starting point, it overwrites existing data" Does it mean the existing data is lost? so how do i keep track of the historical data if it overwrites?</div><div><br>
</div>
<div>Please help me understand with examples.</div><div><br></div><div>Regards,</div><div><br></div><div>Kaushal</div><div><br></div></div>
