本文主要是介绍open-falcon graph 部署，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
目的
搭建 graph 服务
作用
graph是存储绘图数据的组件
graph组件 接收transfer组件推送上来的监控数据
处理query组件的查询请求、返回绘图数据
依赖
mysql db
编译
版本修改
modules/graph/g/g.go
const (VERSION = "20200818"
)
编译
# make graph
go build -o bin/graph/falcon-graph ./modules/graph
graph 服务器搭建
创建目录
mkdir /apps/svr/falcon-plus/graph/{bin,config,logs} -p
配置文件
/apps/svr/falcon-plus/graph/config/cfg.json
{"debug": false,"http": {"enabled": true,"listen": "0.0.0.0:6071"},"rpc": {"enabled": true,"listen": "0.0.0.0:6070"},"rrd": {"storage": "/data/graph/6070"},"db": {"dsn": "falcon:falcontest@tcp(ns-yun-020021.133.com:3307)/graph?loc=Local&parseTime=true","maxIdle": 4},"callTimeout": 5000,"migrate": {"enabled": false,"concurrency": 2,"replicas": 500,"cluster": {"graph-00" : "xx.xx.xx.21:6070","graph-01" : "xx.xx.xx.22:6070","graph-02" : "xx.xx.xx.23:6070","graph-03" : "xx.xx.xx.24:6070"}}
