Build Status


Sos is an extensible, portable, support data collection tool primarily aimed at Linux distributions and other UNIX-like operating systems.

This project is hosted at:

For the latest version, to contribute, and for more information, please visit the project pages or join the mailing list.

To clone the current master (development) branch run:

git clone git://

Reporting bugs

Please report bugs via the mailing list or by opening an issue in the GitHub Issue Tracker

Mailing list

The sos-devel is the mailing list for any sos-related questions and discussion. Patch submissions and reviews are welcome too.

Patches and pull requests

Patches can be submitted via the mailing list or as GitHub pull requests. If using GitHub please make sure your branch applies to the current master as a 'fast forward' merge (i.e. without creating a merge commit). Use the git rebase command to update your branch to the current master if necessary.

Please refer to the contributor guidelines for guidance on formatting patches and commit messages.


User and API documentation is automatically generated using Sphinx and Read the Docs.

To generate HTML documents locally, install dependencies using

pip install -r requirements.txt

and run


Please run make test before sending a pull request, or run the test suite manually using the nosetests command (ideally for the set of Python versions currently supported by sos upstream).


To help get your changes merged quickly with as few revisions as possible please refer to the Contributor Guidelines when submitting patches or pull requests.


Manual Installation

You can simply run from the git checkout now:

$ sudo ./sosreport -a

Or, if you only have python3 installed:

$ sudo python3 ./sosreport -a
  • Note: the sosreport command requires a configuration file: if no sos.conf is present in the /etc directory (i.e. no system installation of sos exists), use the --config option to provide one:
$ sudo python ./sosreport -a --config ./sos.conf

To install locally (as root):

# make install

To build an rpm:

$ make rpm
