Subject Re: Mismatch between numbers in Aggregate Report and InfluxDB via backend listener
Date Mon, 08 May 2017 09:47:59 GMT
Hi,

Perfect for mean, max and min metrics ! Now for percentile, timeboxed don't
makes sense, so we use a large sliding window ( 50 000 as you set ).
I have to check in report what method is use to percentile.

The difference is important in your result ?
