gcvis is a Go CLI tool that visualizes Go program garbage collector trace data (GODEBUG=gctrace output) in real time via a browser graph. It wraps a target command or reads trace data from stdin or a log file.
Use cases
- visualize go garbage collector pauses in real time
- plot gctrace output as graphs
- analyze gc behavior of a go program without modifying its source
- feed gctrace log file into a visualization
- diagnose memory pressure and gc frequency in go services
When to choose
- you need a quick visual of Go GC cycles from GODEBUG=gctrace output
- you cannot modify the target program's source to add profiling
- you are on Go 1.6 and want GC timing graphs
When to avoid
- you need maintained tooling - the project is explicitly unmaintained since 2019
- you are on Go versions newer than 1.6 and need GC timing graphs
- you need full profiling rather than GC trace visualization - use pprof instead
