arrivals models arrival events in a system, e.g.:
- visitors arriving to use a website
- incoming phone calls to an exchange
- ghosts spawning in Pacman
This library was originally developed for use in Artillery, a modern load testing toolkit.
npm install arrivals
Two models of arrival processes are available: Poisson and Uniform (arrivals at a specified constant rate).
//// Poisson process example//var arrivals = ;// Create a Poisson process with the mean inter-arrival time of 500 ms that// will run for 20 seconds:var p = arrivalspoisson;p;p;pstart;
If the last argument (total duration of the process) is omitted, the process
will run until stopped with
//// Uniform arrivals example://var arrivals = ;// Create an arrivals process that will trigger the callback every 500ms for// 20 seconds (for a total of 20000 / 200 = 40 arrivals)var p = arrivalsuniform;p
The last argument (total duration) is optional as in the previous example.
