Expand description

A metadata collector.

Metadata collectors are responsible for collecting metadata from the environment, both at startup and over time as changes to the workload occur. This metadata can represent many things, from basic key/value pairs about specific entities, to fixed relationships between entities, to more dynamic information like the current state of a workload.
