Jellyfish是一款轻量级的, 用Java写的, 分布式微服务实时监控系统，可无缝对接Spring Boot或Spring Cloud工程
Jellyfish提供的监控功能主要分为两个部分：

1. 应用程序日志统一收集和查询
2. 统计和监控SpringBoot应用程序HTTP接口3个指标：请求耗时，错误率，并发度

Jellyfish部署方式
Jellyfish分为服务端和agent端
服务端通常是一个独立的SpringBoot应用或集群，集群模式是通过另一个微服务分布式协作框架tridenter实现的，Jellyfish服务端还需要部署Redis和ElasticSearch
Agent端 通常是加入了jellyfish相关jar包的另一组SpringBoot应用或集群，它们向服务端实时发送数据包。
【分布式微服务监控系统Jellyfish使用介绍】Jellyfish的特性：

1. Jellyfish服务端基于流式计算框架vortex（底层是Netty4），低延迟，高并发，且支持TCP和HTTP两种传输协议
2. Jellyfish服务端的网络通信层依赖vortex框架，支持动态水平扩展，支持数据最终一致性
3. Jellyfish的应用接口统计是准实时的，纯内存计算，默认的统计时间窗口为1分钟（可自定义），但统计的接口数量变多可能会影响实时性，经测试，最大延迟保持在1分钟内，平均延迟在秒级。

Jellyfish系列一共有4个子工程：

1. jellyfish-console
   Jellyfish Web控制台，可独立运行，通常作为服务端，当然你也可以自定义服务 端，通过使用注解@EnableJellyfishServer
2. jellyfish-http-spring-boot-starter
   jar包，Jellyfish监控应用程序接口进行指标统计的Agent程序包
3. jellyfish-slf4j
   jar包，Jellyfish对接slf4j（目前只实现了logback对接），统一应用收集日志的
   agent程序包
   4. jellyfish-spring-boot-starterJellyfish核心jar包, 实现了全部的核心功能

Install

jellyfish-spring-boot-starter com.github.paganini2008.atlantis 1.0-RC1

Jellyfish-console使用说明
如何对接slf4j, 统一收集日志：
你的应用程序需要：

1. pom.xml 添加依赖
   

   jellyfish-slf4j com.github.paganini2008.atlantis 1.0-RC1

   
   
2. 修改logback.xml
   

   tester5 http://192.168.159.1:10010

   
   目前只支持logback, 未来会支持更多
   
3. 先启动Jellyfish-console
   启动命令：java -jar jellyfish-console-1.0-RC1.jar
   默认端口：6100 地址：http://localhost:6100/jellyfish/log/

4. 再启动你的应用程序，此时日志会源源不断的流入Jellyfish Console：

   说明：
   jellyfish服务端从agent端接受来的每行日志数据会保存在es里。

如何对接Spring Boot或Spring Cloud项目，统计HTTP接口指标？
你的应用需要：

1. 修改你的pom.xml, 添加：
   

   jellyfish-http-spring-boot-starter com.github.paganini2008.atlantis 1.0-RC1

   
   
2. 在application.properties加入：
   

   atlantis.framework.jellyfish.brokerUrl=http://localhost:6100# Jellyfish console地址

   
   
3. 使用压测工具测试某一个接口，如图：

Jellyfish接口统计部分调用了vortex的metric模块的sdk,，所以是基于时间序列的，默认统计时间窗口是1分钟，滚动保存前60条数据，历史数据默认不落地，但可以通过实现MetricEvictionHandler和MetricSequencerFactory接口进行扩展，参考vortex metrics
最后，Jellyfish服务端的参考配置：

server.port=6100spring.application.name=jellyfish-console spring.application.cluster.name=jellyfish-console-cluster#management.endpoints.web.exposure.include=* #management.endpoint.health.show-details=always #management.security.enabled=false #spring.boot.admin.client.url=http://localhost:10081atlantis.framework.vortex.bufferzone.collectionName=jellyfish atlantis.framework.vortex.bufferzone.pullSize=100#Elasticsearch Configuration spring.data.elasticsearch.cluster-name=es spring.data.elasticsearch.cluster-nodes=localhost:9300 spring.data.elasticsearch.repositories.enabled=true spring.data.elasticsearch.properties.transport.tcp.connect_timeout=60s#Redis Configuration spring.redis.host=localhost spring.redis.port=6379 spring.redis.password=123456 spring.redis.dbIndex=0
