Analyzes strace output.

Table of Contents


Create logs:

strace -s 0 -ff -o cmd.strace cmd

Analyze logs, with xxx being the first process ID, the analysis will follow forked processes automatically:

strace-analyzer cmd.strace.xxx

Note: Only works with traces created with the usage example above. There is no support for logs that contain output of multiple process IDs and the timed output variants are supported neither. The above-mentioned strace command line yields the shortest output and allows tracing the forked processes without too much effort.


At the moment, strace-analyzer only analyzes reads and writes to the file system:

$ strace -s0 -ff -o tar.strace tar czfv pkgs.tar.gz /var/cache/pacman/pkg/linux-*

$ strace-analyzer tar.strace.10099
