timmy-customtest 1.2.15

timmy-customtest

Python-based tool for Mirantis OpenStack which uses [Timmy](https://github.com/adobdin/timmy) as a backend. Provides the following info about environments and Fuel 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

6.0, 6.1, 7.0, 8.0, 9.0 (non-UCA deployment only)

Prerequisites

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

  • python 2.6 or 2.7

  • root access via public key to any node via Fuel admin network

  • edit configuration file (copy and edit /usr/share/timmy-customtest/timmy-config-default.yaml if using pip install or timmy-config.yaml) to specify Fuel's IP address instead of ``127.0.0.1

  • PyYAML python module should be installed (requirement for Timmy)

• for easy install, install pip yum install python-pip

• install [Timmy](https://github.com/adobdin/timmy) - pip install timmy

• verify the installation - python -c 'import timmy' should not print tracebacks

• if the installation for some reason was not successful, install Timmy manually (for ex. into /root folder):

  1. yum install git; cd /root; git clone https://github.com/adobdin/timmy.git

  2. ln -s /root/timmy/timmy /usr/lib/python2.X/site-packages/timmy # change X to the version of Python 2 available on the system

  3. verify the installation - python -c 'import timmy' should not print tracebacks

Installation and updates

• always update [Timmy](https://github.com/adobdin/timmy) before updating timmy-customtest. To update Timmy if it is installed by pip: pip install --upgrade timmy. If using git directly, do git pull in the folder where you cloned Timmy.

• install timmy-customtest: pip install timmy-customtest

• alternatively, clone without installing: git clone https://github.com/f3flight/timmy-customtest

• To update already installed timmy-customtest, use the same methods as for Timmy (mentioned above)

Usage

• 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 (timmy uses nice and ionice to minimize the impact)

• optionally copy and edit /usr/share/timmy-customtest/timmy-config-default.yaml - for example you can filter nodes by various parameters, then use -c option to specify your edited configuration file (if you have not installed via pip then simply edit timmy-config.yaml)

• run the tool - timmy-customtest

• if you cloned only, then cd into timmy-customtest folder and start the tool by running ./timmy-customtest

• optionally redirect output to a file: timmy-customtest | 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/timmy/info folder (unless you or Timmy have erased it)

• be happy

• data (except stdout which you have to capture manually) is collected into /tmp/timmy/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](http://vim.wikia.com/wiki/Folding).
