Analyzer go-net-http-req-latency

# Name

go-net-http-req-latency - Go net/http Request Latency

This analyzer measures and profiles HTTP request latency in Go applications using the standard net/http package. It captures detailed timing metrics for each request phase, including header processing time, ServeMux routing time, user handler execution time, and response transmission time. The analyzer supports filtering by host, URI, and minimum request duration, and optionally captures network packets for matched requests. It generates line charts and detailed request breakdowns to help identify performance bottlenecks in HTTP request handling pipelines.
