Havoc

A ChaosMonkey style application that can randomly kill processes, as well as TCP and UDP connections. Inspired by dLuna/chaos_monkey.

Basic Usage

havoc:on().

This will use the default options. The following is a list of currently allowed options

avg_wait - The average amount of time you would like to wait between kills. (default 5000)
deviation - The deviation of time allowed between kills. (default 0.3)
process - Whether or not to kill processes. (default true)
tcp - Whether or not to kill TCP connections. (default false)
udp - Whether or not to kill UDP connections. (default false)
nodes - Either a list of atoms for node names, or any value that erlang:nodes/1 accepts.
applications - A list of application names that you want to target. (defaults to all applications except kernel and havoc)
supervisors - A list of supervisors that you want to target. Can be any valid supervisor reference. (defaults to all supervisors)
prekill_callback - A Fun that gets called just before killing.

You can specify options using havoc:on/1.

havoc:on([{avg_wait, 3000}, {deviation, 0.5}, process, tcp])
