Ren et al (2010) Google-Wide Profiling: A Continuous Profiling Infrastructure for Data Centers (IEEE Micro)

Google-Wide Profiling is theoretically an extension of the Digital Continuous Profiling Infrastructure (DCPI) [Anderson et al, 1997] to data centers. It is a continuous profiling infrastructure that samples across machines in multiple data centers and collects various events. GWP collects profiles on stack traces, hardware events, lock contention profiles, heap... [more]
