Zero-Config Go Heap Profiling — Go’s runtime samples heap allocations automatically, but the linker disables this in apps that don’t import runtime/pprof or net/http/pprof. This tour of runtime.mbuckets and /proc/<pid>/mem is a good read if you’ve wondered where pprof data actually lives, or how to grab a heap profile from a process you can’t redeploy.

Aaron explains more ▶️ in this five-minute video.
