A Linux Filesystem Tracing Method Using the Kprobes Linux Dynamic Instrumentation System

초록

영어

A storage performance analysis tool is crucial to finding performance bottlenecks in I/O storage systems and developing efficient storage system architectures or algorithms. Due to the existence of many parallel Linux projects, there are also many trace tools proposed by different authors. This work presents an integrated performance analysis tool for Linux file systems. The tool provides actual time information for Linux file system functions. In contrast to other existing tools, the tool provides a filtering mechanism, a graphical interface, and system-level analysis information without a heavy load of measurement. It may be used by Linux developers or end-users for analyzing file system layers or measuring software performance to find bottlenecks in Linux file systems.
