Returns time series that consist of the median values from the histogram distributions described by the expression.
|hsExpression||Expression describing the histogram series to extract median values from.|
median() histogram function extracts the median value from each histogram distribution described by the expression, and returns those values as time series. A separate time series is returned for each histogram series.
This chart shows the median values of each distribution in the histogram series that is described by the expression
hs(alerting.check.latency.m, customer="perftest"). Because the specified histogram metric has one distribution per minute, this query returns a time series with one median value per minute.
