So for example, if the true count of distinct items is 1,000, the result returned by the approximation algorithm is between 9 about 95% of the time. 99% of the time, results are within +/- 6%.The case statements will always result in 1 or null, so the results can only be something like 1,1,null,1,null. 95% of the time, results are within +/- 4%. SELECT COUNT( DISTINCT CASE WHEN status true THEN 1 END ) AS trues, COUNT( DISTINCT CASE WHEN status false THEN 1 END ) AS false FROM table This will always be 1 or 0.65% of the time, results are within +/- 2%.The approximation algorithm uses a relative error parameter of 2%, for example: If the number of distinct items returned is larger than 100, count_distinct instead uses an approximate algorithm, and displays a message that explains: count_distinct saw more than 100 values, results may be approximate sourcetype'app' eventtype in (eventa,eventb,eventc) stats avg (timea) as 'Avg Response Time' BY MASA eval Avg Response Timeround ('Avg Response Time',2) Output I am getting from above search is two fields MASA and Avg Response Time. If the number of distinct items returned is less than 100, the count_distinct function provides an exact number. Splunk: Stats from multiple events and expecting one combined output. Splunk, Splunk>, Turn Data Into Doing, Data-to-Everything. To order your results, use the sort operator. How can I retrieve count or distinct count of some field values using stats function phaniraj. By default, ordering is not defined inside of groups created using a group-by expression. The search to find this is: indexsf rename as Venue stats count by, Venue table Venue, count sort count In. ![]()
