Go(lang): How to use PPROF heap profile to find memory leaks?

I am trying to use pprof to verify memory leaks.

Can any explain how to read the heap profile that you find at: http://localhost:6060/debug/pprof/heap?debug=1

Also, is it normal that by typing the web command after starting go tool pprof http://localhost:6060/debug/pprof/heap it produces an empty .svg file?

Many Thanks

How to read the heap-profile is explained pretty good in this intel blogpost:

The numbers in the beginning of each entry ("1: 262144 [4: 376832]") represent number of currently live objects, amount of memory occupied by live objects, total number of allocations and amount of memory occupied by all allocations, respectively.

I may help with the second question. You must provide the name of the binary to your command:

go tool pprof YOUR_COMPILED_BINARY http://localhost:6060/debug/pprof/heap
