Notes

Abstract

OOMProf is a Go library that installs a eBPF programs that listen to Linux kernel tracepoints involved in OOM killing and records a memory profile before your Go program is dead and gone. The memory profile can be logged as a pprof file or sent to a Parca server for storage and analysis. This talk will be a deep dive into the implementation and its limitations and possible future directions.
