Description
A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall
Examples.
The percentile remove the highest values when using order by VAL asc, and the lowest values when using order by VAL desc
Note: percentile removes values from one side of the list of values only, therefore if needed, you may run list and percentile twice - once with order by asc, and then with order by desc.
Example 1:
* in log in log.system audit | list process time | order by process time desc | percentile 95system audit | list process time (ms) | order by process time (ms) asc | percentile 95
From the events in system audit log, returns the percentile 95% of the events by column process time., by remove the 5% highest values
Example 2:
timetoprcessRequest != null in log.access | list timetoprcessRequest | order by timetoprcessRequest order by timetoprcessRequest desc | percentile 50 | count | group by URL, timetoprcessRequest | order by timetoprcessRequest desc
From the events in access log, returns the percentile 50% of the events by column timetoprcessRequest, by remove the 50% lowest values. Then groups by the URL and timetoprcessRequest and sorts by timetoprcessRequest descending.
