> Allow fetching CPU cycles usage for all lcores with a single request.
> This endpoint is intended for repeated and frequent invocations by
> external monitoring systems and therefore returns condensed data.
>=20
> It consists of a single dictionary with three keys: "lcore_ids",
> "total_cycles" and "busy_cycles" that are mapped to three arrays of
> integer values. Each array has the same number of values, one per
> lcore,
> in the same order.
