Hi community! My name is YuSheng Zheng and I am an Open Source Promotion Plan 2022 student working with hui li(yousa). This Apache APISIX Profile tool is a OSPP project and the initial content will be developed by us.
Currently we already have a prove-of-concept demo repo for this tool, which can be the initial content for this project in the future: https://github.com/yunwei37/nginx-lua-ebpf-toolkit This POC is written in C/C++ with libbpf, and can be used as a binary cmd tool run on any supported Kernel versions. More details about how it works can be found in this POC repo. I would like to hear comments and suggestions from the community. Thanks very much!
