Kitrace is a software tool that allows dynamic interactive measurement of U NIX 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.
