Open Stack

Hello team,

I want to discuss the tool <https://github.com/adobdin/timmy> that we have
created for MOS as a replacement/alternative of shotgun.



   -

   The tool is based on
   https://etherpad.openstack.org/p/openstack-diagnostics
   -

   Should work fine on the following environments that were tested: 4.x,
   5.x, 6.x, 7.0, 8.0
   -

   Operates non-destructively.
   -

   Can be launched on any host within admin network, provided the fuel node
   IP is specified and access is possible to Fuel and other nodes via ssh from
   local system.
   -

   Parallel launch, only on the nodes that are 'online'. Some filters for
   nodes are also available.
   -

   Commands (from ./cmds directory) are separated according to roles
   (detected automatically) by the symlinks. Thus, the command list may depend
   on release, roles and OS. In addition, there can be some commands that run
   everywhere. There are also commands that are executed only on one node
   according to its role, using the first node of this type they encounter.
   -

   Modular: possible to create a special package that contains only certain
   required commands.
   -

   Collects log files from the nodes using filters
   -

   Some archives are created - general.tar.bz2 and logs-*
   -

   checks are implemented to prevent filesystem filling due to log
   collection, appropriate error shown.
   -

   can be imported in other python scripts (ex.
   https://github.com/f3flight/timmy-customtest) and used as a transport
   and structure to access node parameters known to Fuel, run commands on
   nodes, collect outputs, etc. with ease.
