[rrd-users] Percentile consolidation

[Pablo Chacin]

Greetings

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.

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.

Is there any compiling reason not to include percentiles as consolidation
functions? Is there any plan to do so in the future?

Regards
