cudet

Python-based tool for Mirantis OpenStack, which provides the following info about environments and the Fuel master server:

• custom package versions
• post-install file changes (built-in md5 verification)
• checks if these customizations interfere with MU installation
• provides a list of packages for which there are updated versions available

Supported MOS versions:

9.0

Prerequisites

• designed to run on Fuel node, if running from any other node, these requirements should be met:

  1. python 2.6 or 2.7
  2. root access via public key to any node via Fuel admin network
  3. edit configuration file to specify Fuel's IP address instead of 127.0.0.1

Installation and updates

• install python-cudet: pip install git+https://github.com/toha10/python-cudet
• To update already installed python-cudet use pip to reinstall the package: pip uninstall python-cudet; pip install python-cudet.

Usage

• cudet takes two options from command-line "--env" which allows you to run the check against particular environment and "--node" which allows you to run the check against particular node
• make sure you are ok to IO load your nodes (root partition), since the tool will do md5 verification of each installed package on each node (cudet uses nice and ionice to minimize the impact)
• optionally copy and edit /usr/share/cudet/cudet-config.yaml - for example you can filter nodes by various parameters, then use -c option to specify your edited configuration file.
• run the tool - cudet
• optionally redirect output to a file: cudet | tee results.yaml
• you can regenerate the report any time without actually collecting data from nodes again (connection to Fuel still needed to initialize the array of nodes) - to do this specify -f (--fake) option - this will use data previously collected in /tmp/cudet/info folder (unless you or Cudet have erased it)
• data (except stdout which you have to capture manually) is collected into /tmp/cudet/info if you decide to use/share it

Reading the output

Output is self-explanatory, you might want to view it with Vim and set up folding like so:

:set shiftwidth=2
:set foldmethod=indent
zM

Now you can unfold the sections you are interested in with za and fold them back with zc. More info on Vim wikia.
