gorilla - Can't use go tool pprof with an existing server -

i have existing http server profile. have included _ "net/http/pprof"to imports, , have http server running:

router := createrouter() server := &http.server {     addr:           ":8080",     handler:        router,     readtimeout:    15*time.second,     writetimeout:   15*time.second, //  maxheaderbytes: 4096, }  log.fatal(server.listenandserve()) 

when i'm trying access http://localhost:8080/debug/pprof/ 404 page not found.

that's when using go tool pprof on local machine:

userver@userver:~/desktop/gotest$ go tool pprof http://192.168.0.27:8080/ use of uninitialized value $prefix in concatenation (.) or string @ /usr/lib/go/pkg/tool/linux_amd64/pprof line 3019. read http://192.168.0.27:8080/pprof/symbol failed number of symbols http://192.168.0.27:8080/pprof/symbol  userver@userver:~/desktop/gotest$ go tool pprof http://localhost:8080/debug/pprof/profile read http://localhost:8080/debug/pprof/symbol failed number of symbols http://localhost:8080/debug/pprof/symbol 

same remote client:

macbookair:~ apple$ go tool pprof http://192.168.0.27:8080/ use of uninitialized value $prefix in concatenation (.) or string @ /usr/local/cellar/go/1.3.2/libexec/pkg/tool/darwin_amd64/pprof line 3027. read http://192.168.0.27:8080/pprof/symbol failed number of symbols http://192.168.0.27:8080/pprof/symbol 

it's not explicitly mentioned in documentation, net/http/pprof registers handlers http.defaultservemux.

from source:

func init() {         http.handle("/debug/pprof/", http.handlerfunc(index))         http.handle("/debug/pprof/cmdline", http.handlerfunc(cmdline))         http.handle("/debug/pprof/profile", http.handlerfunc(profile))         http.handle("/debug/pprof/symbol", http.handlerfunc(symbol)) } 

if you're not using default mux have register any/all of want whatever mux you're using, e.g. something mymux.handlefunc("…", pprof.index), etc.

alternatively can listen on separate port (also possibly bound localhost if desired) default mux you've shown.
