Open Stack

Hi Jorge,

Reliability testing automation is the thing that OpenStack Performance team
[1] is working right now. The whole solution will consist of:
 * Fault injection library os-failures [2] that provides an API to do
different kind of faults on different OpenStack clouds. The lib is
currently under active development, our primary goal is to support
Fuel-based clouds and then DevStack-based.
 * Rally as an engine to run different types of test scenarios. As Boris
mentioned the main feature is called "hooks" - it allows to execute
arbitrary code at predefined points of scenario. In our case we will have
plugin that uses os-failures library.
 * Set of scenarios and reports to them - this will go into OpenStack
Performance Docs [3].
 * Rally plugin for results processing. Basically we are interested in
calculating the following metrics:
     * Count errors appeared during scenario execution (e.g. number of
failed requests)
     * Performance degradation - compare performance (e.g. operation
duration) after the failure against sample data collected before
     * MTTR - how long does it takes for all errors to disappear and how
long does it takes for performance to become normal

If you are interesting in contribution, we have meetings by Tuesday at
15:30 UTC at #openstack-performance IRC channel.

Thanks,
Ilya
