Kitrace: Precise interactive measurement of operating systems kernels
Geoff Kuenning · Software Practice and Experience · 1995
Abstract Kitrace is a software tool that allows dynamic interactive measurement of UNIX kernel performance to much greater precision than that available from kernel profiling. Developers can measure, to microsecond resolution, the time required by a complex kernel activity, including time spent waiting for I/O activity or user processes. Kitrace has also proven useful for debugging, especially in situations where traditional breakpointing would be undesirable or would change the behavior of the kernel.
