Resources
In the previous chapter, we saw that we have an internal queue per resource and per cluster group.
A resource is a type of a cluster event. Cellar defines the following cluster events:
bundle: This is a cluster event that corresponds to a bundle action (install, uninstall, start, stop, and so on)config: This is a cluster event that corresponds to a configuration action (create, delete, propset, propappend, propdel, and so on)features: This is a cluster event that corresponds to a feature action (addurl, delurl, install, uninstall, and so on)
Remember that each type of cluster event is managed by a specific handler.
In the filter definition, specify the resource just after cluster_group. This will allow you to filter the events of a specific type (bundle, config, and features).
