Same BT shows different percentiles in Application overview and chart
Hi All,
When i add my own BT to application overview, and compare the response time(50 percentile)/slowest 10% response time(90 percentile) with the same percentiles of charting the same BT, they do not match up at anytime, how are the percentiles calculated at both places?
Hi Andi,
It's well enough to know the difference is due to different resolution, thanks!
Hi
Sorry for the late answer. So - the Percentila Values for the regular measures are calculated per hour. The percentiles for the Baselines are calculated more frequently and is therefore more granular. There is a special algorithm behind that which depends on the actual load.
But - to answer your question: the difference is the different resolution on how often the baseline is calculated. 1 hour resolution wouldnt work for the baseline as we would get the alerts too late.
If you need a more detailed description on the actual algorithm used I can try to hook you up with the technical engineering team.
