NewPeriodicDataSource creates a new data source managing per-node sensor instances for a given metric and periodically collecting data from those.

NewPeriodicDataSourceWithPeriod is the same as NewPeriodicDataSource but with a customizable sampling periode.

NewSyncedSeriesSource creates a new data source managing per-subject synced series data.

PeriodicDataSource is a generic data source periodically querying node-associated sensors for data.

SyncedSeriesSource is a base type for all data sources using synced series data as their data storage solution.

Sensor is an abstraction of some input device capable of probing a node for some metric of type T.
