Gin框架接入pyroscope完美替代pprof实现检测内存泄露

传统检测内存泄露可以看一下我这篇文章Gin框架接入Prometheus,grafana辅助pprof检测内存泄露-CSDN博客

pyroscope被Grafana收购,GPT来总结一下pyroscope的强大之处🐶

pyroscope github地址

pyroscope与grafana的安装

docker compose安装，这里我们其实可以不使用grafana，pyroscope已经是一个很完整的产品，但是我们在grafana里面可以配置数据源，也可以在grafana里面查看，grafana暂时还没有好的pyroscope dashboard

version: '3.8'services:grafana:image: grafana/grafanacontainer_name: grafanaports:- "3000:3000"networks:- monitoringdepends_on:- prometheuspyroscope:image: grafana/pyroscopecontainer_name: pyroscopeports:- "4040:4040"networks:- monitoring    networks:monitoring:driver: bridge

执行

docker-compose up -d

访问Pyroscope http://localhost:4040/ 我们可以看到go语言的各种性能指标与pprof检测的各类指标差不多

Gin框架中间件配置

我们在gin框架中间件中集成这个检测插件

ApplicationName: "simple.golang.app.golang",用于在Pyroscope筛选服务
