A node agent for measuring, processing and forwarding node level metrics.
Open questions:
Are hostname unique with a computing center or is it required to store the cluster name in addition to the hostname?
What about memory domain granularity?
Configuration
Configuration is implemented using a single json document that is distributed over network and may be persisted as file.
Granularity can be either node, or core. Frequency can be set on a per measurement basis.
Supported metrics are documented here.
