Dump Profiles
Once a Go executable is started with the profiling subsystem enabled, you can use curl to connect to the embedded web server and dump various profiles.
The general syntax of the command is:
curl -k https://localhost:<http-port>/debug/pprof/<profile-name>[?debug=1|2]
where profile name can be one of goroutine, heap, threadcreate, block, mutex.
For example, to dump goroutines:
curl -k https://localhost:<http-port>/debug/pprof/goroutine?debug=2 > ~/tmp/goroutine-profile.txt
