This is a very basic plugin with the sole purpose to be used as template for your own plugin development: The Python files included make up for the most basic configurable plugin and are extensively commented. The structure should be complete enough to fulfill the requirements of the Checkmk exchange. If you install and use it without modification, it will just create random alerts.
Included in this package are two files for bakery deployment: the rule set for configuration and a v1 bakery API plug-in. These two files will be ignored by Checkmk Raw, so there is no need for a separate "Hello bakery!" package anymore.
