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：
- 应用程序日志统一收集和查询
- 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。
Jellyfish的特性：
- 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
- 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
- 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：
- 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 - 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 - 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-starter Jellyfish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：
pom.xml 添加依赖
jellyfish-slf4j com.github.paganini2008.atlantis 1.0-RC1 修改logback.xml
tester5 http://192.168.159.1:10010 目前只支持logback, 未来会支持更多
- 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/
- 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：
修改你的pom.xml, 添加：
jellyfish-http-spring-boot-starter com.github.paganini2008.atlantis 1.0-RC1 在application.properties加入：
atlantis.framework.jellyfish.brokerUrl=http://localhost:6100 # Jellyfish console地址- 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
