<div dir="ltr"><div><div>Greetings</div><div><br></div><div>Been able to pre-calculate an store certain data percentiles, like media an 95 percentile is a common requirement for any metrics database, as these aggregation functions are much more stable and representative of data than the average or maximun values.</div><div><br></div><div>I saw that the mean was recently included as an consolidation function in rrdtool, but still there's no possible to calculate other arbitrary percentiles. Interestingly, percentiles have been available when retrieving data for graphs or reporting.</div></div><div><br></div><div>Is there any compiling reason not to include percentiles as consolidation functions? Is there any plan to do so in the future?</div><div><br></div><div>Regards</div><div><br></div><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div style="font-family:arial;font-size:small">---------------------------</div><div style="font-family:arial;font-size:small">Pablo Chacin</div><div style="font-family:arial;font-size:small">CTO</div><div style="font-family:arial;font-size:small">SenseFields SL</div><div style="font-family:arial;font-size:small">Tlf (+34) 93 <a value="+34932504598" style="color:rgb(17,85,204)">250 45 98</a></div><div style="font-family:arial;font-size:small">Gran Via 674, principal 1º</div><div style="font-family:arial;font-size:small">08010 Barcelona, Spain</div><div style="font-family:arial;font-size:small"><a href="http://www.sensefields.com/" style="color:rgb(17,85,204)" target="_blank">http://www.sensefields.com</a> </div><div style="font-family:arial;font-size:small"><br></div><div><div><br></div><div><font size="1" face="arial narrow, sans-serif">This message was directed exclusively at the recipient and contains privileged and confidential information.
