Performance Co-Pilot Protocol (PCP)

Performance Co-Pilot provides a framework and services to support system-level performance monitoring and management. For live monitoring, PCP uses a TCP based protocol for transferring information about performance metrics between collector and monitor processes.


PCP was originally developed at Silicon Graphics Inc (SGI) in the late 90s. It is now an open source project with contributors around the globe.
