Profiling

etcd exposes profiling information from the Go pprof package over HTTP. The basic browseable interface can be found at http://127.0.0.1:4001/debug/pprof.

NOTE: In the following examples you need to ensure that the ./bin/etcd is identical to the ./bin/etcd that you are targetting (same git hash, arch, platform, etc).

Heap memory profile

go tool pprof ./bin/etcd http://127.0.0.1:4001/debug/pprof/heap

CPU profile

go tool pprof ./bin/etcd http://127.0.0.1:4001/debug/pprof/profile

Blocked goroutine profile

go tool pprof ./bin/etcd http://127.0.0.1:4001/debug/pprof/block
