Well-known plugin categories
A plugin that outputs a graph_category attribute will get the graph grouped with other plugin graphs refering to the same category.
To get a clear and user-friendly overview in Munin website, the list of categories should be small and meaningful.
This table lists our well-known graph categories (as partly already implemented in the plugins Core Collection) and a description, which data sources are suitable for the different categories.
As we are just sorting out category terms from the contrib repository, the list is meant as a proposal to discuss and comment. You can do so on our mailing list or here in the wiki.
Plugin contributors should refer to this categories when uploading their plugins to the repository. Important: Please write the config line for plugins category in a concrete string (e.g. graph_category memory). The gallery build script scans for such a line in the plugins source code and needs it. Otherwise (e.g. use of variables) your plugin will only be shown under "other".
