  • go pprof 性能分析工具使用

    使用gin web框架开发,使用 github.com/gin-contrib/pprof 包

    import "github.com/gin-contrib/pprof"
    
    pprof.Register(router)

    输出图片相关格式需要先安装graphviz,graphviz安装地址如下

    https://graphviz.org/download/

    web运行起来后,通过命令行执行命令

      查看内存使用情况:

        go tool pprof http://ip:port/debug/pprof/heap

    提醒:如果进入(pprof)模式,输入web命令,提示错误信息为failed to execute dot. Is Graphviz installed? Error: exec: "dot": executable file not found in %PATH%,可能的原因如下:

    1. 一个可能是没有安装上面的工具

    2. 没有把graphviz/bin目录配置到path环境变量

    3. 如果使用goland等IDE工具打开的terminal,请移步cmd窗口

    具体使用:
