cc-metric-collector

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.
