strace-analyzer
Analyzes strace output.
Table of Contents
<!-- toc --> <!-- tocstop -->Usage
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.
Analysis
At the moment, strace-analyzer only analyzes reads and writes to the file
system:
