Nginx-With-eBPF

第三届eBPF开发者大会主题分享：基于eBPF的Nginx可观测性实践

构建

sudo bash ./build_nginx.sh
sudo bash ./build_bpftrace.sh

sudo bash ./start_nginx.sh

# list all uprobe
sudo bpftrace -l 'uprobe:/opt/nginx/sbin/nginx:*'

工具集

tools/ngx_http_process_request.bt

用法: sudo bpftrace -I nginx_headers ngx_http_process_request.bt

用途：探测Nginx请求URI
