LazyFS produces a log file when the option log_all_operations is set to true and outputs to a path when the option logfile is given.
To simplify the visualization of the log, this parser can be used. It allows to:
- Filter specific system calls
- Filter system calls for a specific path
- Create a visualization graph from the log
- Group system calls, i.e., if the same syscalls are called sequentially, the program identifies this repetition and simplifies the output
- Obtain information of the location of writes bigger than a page (this value is also configurable)
An example of output:
To understand the different options run:
./parse.py -h
