I use kamon for a scala project and collect some metrics with Kamon.histogram
. I use stastd + graphite + grafana as the backend. I record about 200 events per second.
The statsd has the flushInterval of flushInterval: 10000,
(10 seconds), and kamon has tick-interval = 10 seconds
.
I noticed that the median (and all the other percentiles) are computed wrong. Furthermore, when I change the tick-interval
of kamon to 1second, the median value changes, becoming closer to the correct one (but still not quite).
