However, such a feature comes at the cost of hardware abstraction, making it more difficult or even impossible to access several low-level functionalities. Overseer is a Java framework that makes it possible on Linux systems by simplifying access to real-time measurement of low-level data such as Hardware Performance Counters (HPCs), IPMI sensors, and Java VM internal events. Overseer supports functionalities such as HPC-management, process/thread affinity settings, hardware topology identification, as well as power-consumption and temperature monitoring. In this paper we describe Overseer and how to use it to extend Java applications with functionalities not provided by the default runtime. A public release of Overseer is available.}, keywords = {hardware performance counters, Java, monitoring, Overseer}, isbn = {978-1-4503-0935-6}, doi = {http://doi.acm.org/10.1145/2093157.2093179}, author = {Achille Peternier and Daniele Bonetta and Walter Binder and Cesare Pautasso} }
