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.

Tags in InfluxDB are used to build indexes over the stored data. InfluxDB-Tags have no
relation to each other, they do not depend on each other and have no hierarchy.

This project also works as a time-series database and uses the InfluxDB line protocol.
Unlike InfluxDB, the data is indexed by one single strictly hierarchical tree structure.
A selector is build out of the tags in the InfluxDB line protocol, and can be used to select
a node (not in the sense of a compute node, can also be a socket, cpu, ...) in that tree.
The implementation calls those nodes `level` to avoid confusion.
It is impossible to access data only by knowing the *socket* or *cpu* tag, all higher up levels have to be specified as well.

Example selectors:
1. `["cluster1", "host1", "cpu0"]`: Select only the cpu0 of host1 in cluster1

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.
