Contributed Munin Plugins

This plethora of plugins covering various topics was contributed by many different users of munin.

See the gallery for a browsable overview of these plugins.

Purpose of this repository

This repository of contributed plugin strives to achieve the following goals:

• allow users to find interesting plugins
• allow contributors to publish their plugins
• simplify cooperative maintenance of plugins

Contributed plugins are maintained primarily by their authors. You may file bug reports for plugin issue here in this repository (munin-contrib), but please do not forget to notify the author of the plugin (see the plugin's documentation), too.

Please note, that this repository is not supposed to be a dumping site for random plugins of low quality. The related infrastructure (e.g the gallery or automated tests) require a certain level of quality. Please see below for details.

Submit a new plugin

1. check if a similar plugin exists and if it can be extended/changed instead of adding a new plugin
   • please avoid code copies - they are a maintenance burden
2. add documentation including configuration, author, license and magic markers
3. pick a suitable category
4. use style check tools for the language of the plugin (e.g. perl: perlcritic, shell: shellcheck, python: flake8, ruby: rubocop)
5. pick a suitable name and location
6. bonus:
   • use the multigraph approach for non-trivial plugins
   • add example graphs for the gallery
   • support dirtyconfig if it is suitable
7. open a pull request with your new plugin or send it attached to an email to the mailing list

See the plugin development documentation for more details.

Modify an existing plugin

• try to keep the plugin backwards compatible (e.g. keep data fieldnames unchanged)
  • improvements of code quality and features can justify incompatible changes of existing plugins
• bonus:
  • improve the existing plugins according to the wishlist for new plugins
  • upgrades from simple plugins to a multigraph plugin are welcome

Plugin name and location

The following descriptions are intentions - they do not necessarily describe the current state for all plugins. Please open a pull request if you want to align the current structure along the goals outlined below:

• the top level directory should describe a related software or vendor
  • use concepts or platforms only if it is really necessary (e.g. cpu, bsd, memory)
• subdirectories are usually not required
