Golang Performance Test package is located under the Net/http package of Pprof, the relevant introduction can refer to the specific official documents
The Golang performance test is particularly easy to use, with the introduction of the placement in the main package directly:
Import _ "Net/http/pprof"
After that, add the following line of code in the main function:
Go func () {log. Println (http. Listenandserve ("0.0.0.0:6060", Nil)} ()
At this point, through the above two steps to complete the pprof of the implant, that is, we can carry out the relevant performance testing.
Use the command:
Go tool pprof http://localhost:6060/debug/pprof/heap View stack
When you enter a Web command, the page will automatically appear with the corresponding SVG chart, and the corresponding chart appears as follows:
When the program is running, the corresponding port 6060 is already in the listening state, so we can also directly access through the browser: http://www.localhost:6060
How to see the CPU, Memory, I/O, timed refresh and other related information, can be used to the corresponding official document view.
How the specific SVG diagram is generated, and how to generate the corresponding chart by code see my other Blog: Graphviz program generates various types of diagrams in detail
