What page do I request to get the profiling information? I'm using filebeat, but as I understand it, the -httpprof switch is available to all the beats. ---

The `-httpprof` exposes the standard Golang http endpoint (`/debug/pprof`) so you can use their documentation to find more information about how to profile Golang apps. These are the primary profiling docs: - [https://golang.org/pkg/net/http/pprof/](https://golang.org/pkg/net/http/pprof/) - [https://blog.golang.org/profiling-go-programs](https://blog.golang.org/profiling-go-programs) Also as a side effect of running `-httpprof` it also exposes some metrics at `/debug/vars`. These are mostly provided by the Go [expvar package](https://golang.org/pkg/expvar/) but there are a few metrics from libbeat. ---

Andrew, Thanks for the outstanding reply. That was just what I needed. Thanks very much! -KwM- ---
