The cc-metric-store provides a simple in-memory time series database for storing metrics of cluster nodes at preconfigured intervals. It is meant to be used as part of the [ClusterCockpit suite](https://github.com/ClusterCockpit). As all data is kept in-memory (but written to disk as compressed JSON for long term storage), accessing it is very fast. It also provides aggregations over time *and* nodes/sockets/cpus.

### Test the complete setup (excluding ClusterCockpit itself) ## Test the complete setup (excluding cc-backend itself)
There are two ways for sending data to the cc-metric-store, both of which are supported by the [cc-metric-collector](https://github.com/ClusterCockpit/cc-metric-collector). This example uses Nats, the alternative is to use HTTP. There are two ways for sending data to the cc-metric-store, both of which are
