一、skywalking介绍

SkyWalking是有国内开源爱好者吴晟开源并提交到Apache孵化器的开源项目，2017年12月SkyWalking成为Apache国内首个个人孵化项目，2019年4月17日SkyWalking从Apache基金会的孵化器毕业成为顶级项目，目前SkyWalking支持Java、.Net、Nodejs、Go、Python等探针，数据存储支持MySQL、Elasticsearch等，SkyWalking与Pinpoint相同，对业务代码无侵入，不过探针采集数据粒度相较于Pinpoint来说略粗，但性能表现优秀，目前SkyWalking增长势头强劲，社区活跃，中文文档齐全，没有语言障碍，支持多语言探针，这些都是SkyWalking的优势所在，还有就是SkyWalking支持很多框架，包括国产框架，例如，Dubbo、gRPC、SOFARPC等，同时也有很多开发者正在不断向社区提供更多插件以支持更多组件无缝接入SkyWalking

二、Skywalking支持的集群模式如下

2.1、zookeeper

2.2、kubernetes

2.3、consul

2.4、etcd

2.5、nacos

三、Skywalking集群配置

3.1、修改第一台服务器的application.yml

3.7、修改cluster，采用nacos集群

3.8、查看nacos

 3.9、查看skywalking集群

四、skywalking自监控

4.1、启动prometheus

4.2、配置 skywalking
