Pprof
pprof is Go’s profiling toolset and package ecosystem for collecting, analyzing, and visualizing runtime performance profiles.
Cloud Observability in Action
net/http/pprof is a Go package that exposes runtime profiling data through HTTP handlers.
- How it is used
- Supports developer observability by exposing, collecting, analyzing, and visualizing runtime profiles for performance troubleshooting.
- How deep it goes
- Explains HTTP exposure, interactive analysis, graph rendering, and protobuf structure, but stops short of detailed profile internals.
- Examples
- Uses a Go CPU workload, goroutine call graphs, pprof shell rankings, protobuf decoding, and an OpenTelemetry collector scraped by Parca.
- What you can do after
- Diagnose/debug Go and service-runtime hotspots by collecting profiles, ranking functions, rendering graphs, and querying historical samples.
100 Go Mistakes and How to Avoid Them
net/http/pprof is a Go standard-library package that exposes runtime profiling data through HTTP handlers.
- How it is used
- Uses pprof to investigate performance issues, contention, and possible memory leaks.
- How deep it goes
- Explains HTTP setup, available profiles, and CPU sampling behavior.
- Examples
- Shows a Go HTTP server exposing pprof and a go tool pprof command for opening a profile.
- What you can do after
- Apply it via net/http/pprof to expose profiles and go tool pprof to inspect collected data.
