Open Stack

(Crossposting to operators list, as audience here might be more interested
in such solution then in developers list).

Hi, fellow stackers,

There was a conversation during 'Enhance debugability' session at the
summit about Diagnostic API which allows gate to get 'state of world' of
OpenStack installation. 'State of world' includes hardware- and operating
system-level configurations of servers in cluster.

This info would help to compare the expected effect of tests on a system
with its actual state, thus providing Tempest with ability to see into it
(whitebox tests) as one of possible use cases. Another use case is to
provide input for validation of OpenStack configuration files.

We're putting together an initial version of data model of API with example
values in the following etherpad:
https://etherpad.openstack.org/p/icehouse-diagnostic-api-spec

This version covers most hardware and system-level configurations managed
by OpenStack in Linux system. What is missing from there? What information
you'd like to see in such an API? Please, feel free to share your thoughts
in ML, or in the etherpad directly.
