Jellyfish 是一款轻量级的, 用 Java 写的, 散布式微服务实时监控零碎，可无缝对接 Spring Boot 或 Spring Cloud 工程
Jellyfish 提供的监控性能次要分为两个局部：
- 应用程序日志对立收集和查问
- 统计和监控 SpringBoot 应用程序 HTTP 接口 3 个指标：申请耗时，错误率，并发度
Jellyfish 部署形式
Jellyfish 分为服务端和 agent 端
服务端 通常是一个独立的 SpringBoot 利用或集群，集群模式是通过另一个微服务分布式合作框架 tridenter 实现的，Jellyfish 服务端还须要部署 Redis 和 ElasticSearch
Agent 端 通常是退出了 jellyfish 相干 jar 包的另一组 SpringBoot 利用或集群，它们向服务端实时发送数据包。
Jellyfish 的个性：
- Jellyfish 服务端基于流式计算框架 vortex（底层是 Netty4），低提早，高并发，且反对 TCP 和 HTTP 两种传输协定
- Jellyfish 服务端的网络通信层依赖 vortex 框架，反对动静程度扩大，反对数据最终一致性
- Jellyfish 的利用接口统计是准实时的，纯内存计算，默认的统计工夫窗口为 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，最大提早放弃在 1 分钟内，均匀提早在秒级。
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，当然你也能够自定义服务 端，通过应用注解 @EnableJellyfishServer - jellyfish-http-spring-boot-starter
jar 包，Jellyfish 监控利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），对立利用收集日志的
agent 程序包
4. jellyfish-spring-boot-starter Jellyfish 外围 jar 包, 实现了全副的外围性能
Install
<dependency>
<artifactId>jellyfish-spring-boot-starter</artifactId>
<groupId>com.github.paganini2008.atlantis</groupId>
<version>1.0-RC1</version>
</dependency>Jellyfish-console 应用阐明
如何对接 slf4j, 对立收集日志：
你的应用程序须要：
-
pom.xml 增加依赖
<dependency> <artifactId>jellyfish-slf4j</artifactId> <groupId>com.github.paganini2008.atlantis</groupId> <version>1.0-RC1</version> </dependency> -
批改 logback.xml
<?xml version="1.0" encoding="utf-8" ?> <configuration> <appender name="logTracker" class="indi.atlantis.framework.jellyfish.slf4j.logback.HttpTransportClientAppender"> <applicationName>tester5</applicationName> <!-- 批改成你的 applicationName --> <brokerUrl>http://192.168.159.1:10010</brokerUrl> <!-- 批改 Jellyfish console 地址 --> </appender> <!-- omit other configuration --> <root level="info"> <appender-ref ref="STDOUT" /> <appender-ref ref="INFO" /> <appender-ref ref="ERROR" /> <appender-ref ref="logTracker" /> <!-- 援用你定义的 appender --> </root> </configuration>目前只反对 logback, 将来会反对更多
- 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：
阐明：
jellyfish 服务端从 agent 端承受来的每行日志数据会保留在 es 里。
如何对接 Spring Boot 或 Spring Cloud 我的项目，统计 HTTP 接口指标？
你的利用须要：
-
批改你的 pom.xml, 增加：
<dependency> <artifactId>jellyfish-http-spring-boot-starter</artifactId> <groupId>com.github.paganini2008.atlantis</groupId> <version>1.0-RC1</version> </dependency> -
在 application.properties 退出：
atlantis.framework.jellyfish.brokerUrl=http://localhost:6100 # Jellyfish console 地址 - 应用压测工具测试某一个接口，如图：
接口列表：
点击 View
上图显示的是并发度，QPS, 均匀响应工夫

}Jellyfish 接口统计局部调用了 vortex 的 metric 模块的 sdk,，所以是基于工夫序列的，默认统计工夫窗口是 1 分钟，滚动保留前 60 条数据，历史数据默认不落地，但能够通过实现 MetricEvictionHandler 和 MetricSequencerFactory 接口进行扩大，参考 vortex metrics
