With advent of the analysis phase of LHC data-processing, interest in PROOF technology has considerably increased. While setting up a simple PROOF cluster for basic usage is reasonably straightforward, exploiting the several new functionalities added in recent times may be complicated. PEAC, standing for PROOF Enabled Analysis Cluster, is a set of tools aiming to facilitate the setup and management of a PROOF cluster. PEAC is based on the experience made by setting up PROOF for the ALICE analysis facilities. PEAC allows to easily build and configure ROOT and the additional software needed on the cluster and features its own distribution system based on xrootd and Proof on Demand (PoD). The latter is also used for resource management (start, stop or daemons). Finally, PEAC sets-up and configures dataset management (using the afdsmgrd daemon), as well as cluster monitoring (machine status and PROOF query summaries) using MonAlisa. In this respect, a Monalisa page has been dedicated to PEAC users, so that a cluster managed by PEAC can be automatically monitored. In this talk we present and describe the main components of PEAC and show details of the existing facilities using it.
