在程序中添加一行代码即可启动服务：
import _ "net/http/pprof"
func main() {
http.ListenAndServe("0.0.0.0:6060", nil) // 启动服务
}
先启动程序：
go run .\main.go
使用方法
第一种：使用浏览器访问：http://127.0.0.1:6060/debug/pprof/
go tool pprof1）查看堆内存使用
在控制台输入：
PS E:\go\src\test> go tool pprof http://127.0.0.1:6060/debug/pprof/heap
Fetching profile over HTTP from http://127.0.0.1:6060/debug/pprof/heap
Saved profile in C:\Users\Administrator\pprof\pprof.alloc_objects.alloc_space.inuse_objects.inuse_space.010.pb.gz
Type: inuse_space

Entering interactive mode (type "help" for commands, "o" for options)
(pprof) top
Showing nodes accounting for 512.17kB, 100% of 512.17kB total

top 命令会列出5个统计数据：
flat： 本函数占用的内存量
flat%： 本函数内存占使用内存总量的百分比
sum%： 前面每一行flat百分比的和
cum： 累计量，main函数调用了函数f，函数f占用的内存量，也会记录进来
cum%： 累计量占总量的百分比
2）查看goruntine
在控制台输入：
PS E:\go\src\test> go tool pprof http://127.0.0.1:6060/debug/pprof/goroutine
Fetching profile over HTTP from http://127.0.0.1:6060/debug/pprof/goroutine

Type: goroutine
