参数	是否必须	含义
ApplicationName	Required	服务名称
ServerAddress	Required	Logtail 采集配置启动的接收端地址
Tags["hostname"]	Required	本地地址，建议使用os.Getenv("HOSTNAME")，可进行多节点性能对比

   package main

import "github.com/pyroscope-io/client/pyroscope"

func main() {
	// These 2 lines are only required if you're using mutex or block profiling
	// Read the explanation below for how to set these rates:
	runtime.SetMutexProfileFraction(5)
	runtime.SetBlockProfileRate(5)

	pyroscope.Start(pyroscope.Config{
		ApplicationName: "simple.golang.app",

		// replace this with the address of pyroscope server
		ServerAddress: "http://pyroscope-server:4040",

		// you can disable logging by setting this to nil
		Logger: pyroscope.StandardLogger,

		// optionally, if authentication is enabled, specify the API key:
		// AuthToken:    os.Getenv("PYROSCOPE_AUTH_TOKEN"),

		// you can provide static tags via a map:
		Tags: map[string]string{"hostname": os.Getenv("HOSTNAME"), "environment": "test", "version": "1.0"},

		ProfileTypes: []pyroscope.ProfileType{
			// these profile types are enabled by default:
			pyroscope.ProfileCPU,
			pyroscope.ProfileAllocObjects,
			pyroscope.ProfileAllocSpace,
			pyroscope.ProfileInuseObjects,
			pyroscope.ProfileInuseSpace,

			// these profile types are optional:
			pyroscope.ProfileGoroutines,
			pyroscope.ProfileMutexCount,
			pyroscope.ProfileMutexDuration,
			pyroscope.ProfileBlockCount,
			pyroscope.ProfileBlockDuration,

DEMO

部署结构

本Demo 提供Kubernetes 部署，部署模型为一个Pod 中含有2个container：

1. container1 基于Python构建，负责模拟请求产生。
2. container2 基于Go构建,复杂接收请求产生。

打包

sh tag.sh

部署

kubectl apply -f deployment.yaml
