torch

A script that glues perf CPU sampling and Brendan Gregg's visualizer to generate FlameGraphs.

Requirements

Usage: ./torch.sh [options] pid

Options:
-d, --duration <num>  duration of sampling in seconds [default: 10]
-o, --output <file>   file to save flamegraph to [default: ./flamegraph.svg]
-h, --help            this message

Examples

Greatly improved compatibility by using bash

On systems where sh isn't just a link to bash, using a sh shebang doesn't work. This changes it to explicitly use a bash shebang instead of a sh shebang, which improves compatibility with many linux distros.

Make the script callable from anywhere

Currently torch.sh can only be called by going to the program directory and running ./torch.sh directly. This isn't useful when using other build scripts that automatically generate flamegraphs. Thus, I propose this as a solution that allows both local usage as well as PATH-compatible usage.

All three scripts need to be in the same path in order to work, as I've not implemented link following.
