Profile a Running Process
Assuming that your local 127.0.0.1 address is aliased to "localhost.somedomain.com" in /etc/hosts and the certificates are issued for "localhost.somedomain.com", set CERT_PATH to the directory that contains and and:
export CERT_PATH=/Users/ovidiu/some-project/config
go tool pprof -http 127.0.0.1:8080 -tls_cert ${CERT_PATH}/localhost.somedomain.com.chain.pem -tls_key ${CERT_PATH}/localhost.somedomain.com.key.pem https://localhost.somedomain.com:8443
Inspect a Running Process with a Browser
Go to https://localhost.somedomain.com:8443/debug/pprof/
Dump the Goroutines into a Text File
curl -k https://localhost:8443/debug/pprof/goroutine?debug=2
Replace the port with the actual HTTP(S) port the process is listening on.
