This is a demo performance profiler, written to accompany the Pixie blog post. It shows how to get sample stack traces for performance profiling, using eBPF.

You must have the BCC development package installed. On Ubuntu, the package can be installed as follows:

sudo apt install libbpfcc-dev

Other distributions have similar commands.

To compile, execute the following command:

make

A demo application to profile is included: toy_app/sqrt.go

The BPF performance profiler is run as follows:

sudo ./perf_profiler <target pid> <duration>

To run it on the demo app for 30 seconds, run the following command in a separate terminal:

sudo ./perf_profiler $(pgrep -f "sqrt") 30
