As fine grained power monitoring becomes crucial in
data centers, a challenge raises on how to correctly map
server identities to power circuits. Power provisioning,
power capping, and power tracking all depend on accurately
accounting which server consumes power from
which circuit. Manual survey is cumbersome and error
prone. We describe a solution, called Red Pill, that
can systematically and automatically identify the mapping.
The idea is to generate a power consumption pattern
(a.k.a. a signature) by controlling CPU utilization,
and to reliably detect it from circuit-level power measurements.
We describe our implementation of the Red
Pill system and evaluate it with real data traces.
