LMI command for power management.

pip install openlmi-scripts-powermanagement==0.4.0



Client-side python libraries for system management through OpenLMI providers.

It comprises of small python eggs targeted on one or more OpenLMI providers. We call these eggs scripts. They are installed separately although they can depend on each other.

They contain python library itself as well as command line interface. This interface is registered with LMI Meta-command which is a part of OpenLMI Tools. LMI Meta-command loads it and offers to interface with broker through command line.

For more information please refer to online documentation on pythonhosted.


Each subdirectory of commands/ contains library for interfacing with particular set of OpenLMI providers. Each contains its own file, that handles its installation and registration of script. They have one common feature. Each such must pass entry_points dictionary to the setup() function, wich associates commands defined in script with its name with LMI Meta-command.


Code base is written for python 2.7. There are following python dependencies:

  • openlmi-tools >= 0.9.1 (tools-PyPI)
  • python-docopt
  • pandoc


Use standard setuptools script for installation:

$ cd openlmi-scripts/commands/$CMD
$ make setup
$ python install --user

This installs particular client library and command line interface for LMI Meta-command.

Script eggs are also available on PyPI, install them with:

$ # add any provider you want to interact with
$ pip install --user openlmi-scripts-service openlmi-scripts-software

Developing lmi scripts.

This documents how to quickly develop lmi scripts without the need to reinstall python eggs, when anything is changed. This presumes, that the development process takes place in a git repository checked out from git. It can be located anywhere on system.

Before we start with setting up an environment, please double check that you don't have installed anything from openlmi-scripts in system path (/usr/lib/python2.7/site-packages/lmi/scripts should not exist). And make sure, that user path is also cleared:

$ rm -rf $HOME/.local/lib/python2.7/site-packages/lmi*
$ rm -rf $HOME/.local/lib/python2.7/site-packages/openlmi*

Install all dependencies (named above).

Either via rpms (on Fedora or RHEL) or from respective git repositories or from PyPI.

Let's setup an environment:

  1. Create a workspace directory for current $USER (let's call it a WSP). This is a place, where our eggs and binaries will be "installed". It can be located anywhere, for example:

    $ WSP=~/.python_workspace $ mkdir $WSP

  2. Add workspace to your python path to make all modules installed there importable (you can add this to your ~/.bashrc):


  3. Add workspace to your PATH, so the installed binaries can be run:

    $ export PATH="$WSP:$PATH"

  4. Now let's "install" to our workspace. First cd to checked out openlmi-scripts repository.

  5. Install them and any commands you want -- possibly your own

    $ DEVELOPDIR="$WSP" make develop-all

Now any change made to openlmi-scripts is immediately reflected in LMI Meta-command.

Uploading to PyPI

Since PyPI expects README file to be in a reStructuredText markup language and the one present is written in markdown, it needs to be converted to it. So please make sure you have pandoc installed before running:

$ make upload


All the scripts share the same version. Version string resides in VERSION file in root directory. When changed, all scripts need to be regenerated. This is done with:

$ make setup-all

Makefile rules

There are various rules provided to ease the development. Most of them may be applied to all commands/libraries at once. They are:

  • clean - remove temporary and generated files
  • develop - install library in developing mode
  • doc - build html documentation
  • readme - create README.txt file out of
  • sdist - creates source tarball in dist directory
  • setup - writes a and doc/ files from their skeletons
  • upload - upload to PyPI
  • upload-docs - upload documentation to pythonhosted

Each script's Makefile has the same interface. The root Makefile is an exception. It takes care of command libraries. It defines all the rules above with -all suffix. They operate on all subcommands at once. Such rules are:

  • clean-all
  • doc-all
  • develop-all
  • setup-all
  • upload-all
  • upload-docs-all

To limit the set of commands that shall be processed, the COMMANDS environment variable may be used. For example following command:

$ COMMANDS='storage software networking' make clean-all

Will clean storage, software and networking directories.
