# 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](https://github.com/ClusterCockpit/cc-specifications/blob/master/metrics/lineprotocol.md).
