Summary: Fix SLA percentile calculation
Key: AURORA-1827
URL: https://issues.apache.org/jira/browse/AURORA-1827
Project: Aurora
Issue Type: Story
Reporter: Reza Motamedi
Priority: Trivial
The calculation of mttX (median-time-to-X) depends on the computation of
percentile values. The current implementation does not behave nicely with a
small sample size. For instance, for a given sample set of {50, 150},
50-percentile is reported to be 50. Although, 100 seems a more appropriate
return value.
One solution is to modify `SlaUtil` to perform an extrapolation when the sample
size is small or when the corresponding index to a percentile value is not an
integer.
