There were some interfaces added to the openpower namespace for this kind  
of thing.   
https://github.com/openbmc/phosphor-dbus-interfaces/tree/master/org/open_power/Sensor/Aggregation/History

The application implementing them is in the phosphor-power repository  
(power-supply).

To implement the Redfish Telemetry service would we need to store them on  
the BMC as well?
