A host program implementation for linux file system tracing method using the kprobes linux dynamic instrumentation system

Abstract

A storage performance analysis tool is crucial to finding performance bottlenecks in I/O storage systems and developing efficient storage system architectures or algorithms. This work is based on 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. This paper describes a host program implementation for the performance analysis tool. 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.
