OS monitoring (CPU, memory and network traffic) using SNMP, Munin or Erlang agents on remote servers.XML configuration system; several sessions can be used to simulate different type of users. User think-times and the arrival rate can be randomized using a probability distribution.In contrast to many other event-based apps it doesn't use callbacks, instead using light-weight processes, through gevent.This allows you to write very expressive scenarios in Python without complicating your code with callbacks.Report designer tool enables design/configuration of customized load testing reports.Gatling - Open source stress-testing tool developed in Scala.
