Production systems are commonly plagued by intermittent problems that are difficult to diagnose. This paper describes a new diagnostic tool, called Chopstix, that continuously collects profiles of low-level OS events (e.g., scheduling, L2 cache misses, CPU utilization, I/O operations, page allocation, locking) at the granularity of executables, procedures and instructions.
