Count the number of events. The latest event is used as a base to build the event returned by this funcion.

Takes a number of events, a comparator and a list of events. Sort the events based on the :metric field and by using the comparator and Return the first nb events.

Takes a list of event and returns the event with the biggest metric

Takes a list of events and returns the metrics mean. The latest event is used as a base to build the event returned by this funcion.

Takes a list of event and returns the event with the smallest metric

Takes a list of events Divide the first event :metrìc field by all subsequent events :metric

Throws if it divides by zero.

Takes a list of events and compute the rate for them. Use the most recent event as a base for the new event.

Sample a sequence of events at points. Returns events with the :quantile key set to the computed quantile. For instance, (sorted-sample events 0 1) returns a 2-element seq of the smallest event and the biggest event, by metric. The first has a quantile set to 0 and the second one set to in 1. Useful for extracting histograms and percentiles.

When s is empty, returns an empty list.

Returns the events in seqable s, sorted and taken at each point p of points, where p ranges from 0 (smallest metric) to 1 (largest metric). 0.5 is the median event, 0.95 is the 95th’ percentile event, and so forth. Ignores events without a metric.

Sum all events :metric. Use the most recent event as a base for the new event.
