Hi Team,

There is a telemetry proposal in docs and repository.
https://github.com/openbmc/docs/blob/master/designs/telemetry.md
https://github.com/openbmc/telemetry

The proposal seems promising and complete.
What is the implementation status?


Thanks,
Troy Lee

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_po=
wer/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?
