[转帖]springboot中使用skywalking实现日志追踪

SkyWalking分布式追踪系统
介绍
Skywalking是一个国产的开源框架，2015年有吴晟个人开源，2017年加入Apache孵化器，国人开源的产品，主要开发人员来自于华为，2019年4月17日Apache董事会批准SkyWalking成为顶级项目，支持Java、.Net、NodeJs等探针，数据存储支持Mysql、Elasticsearch等，跟Pinpoint一样采用字节码注入的方式实现代码的无侵入，探针采集数据粒度粗，但性能表现优秀，且对云原生支持，目前增长势头强劲，社区活跃。
Skywalking是分布式系统的应用程序性能监视工具，专为微服务，云原生架构和基于容器（Docker，K8S,Mesos）架构而设计，它是一款优秀的APM（Application Performance Management）工具，包括了分布式追踪，性能指标分析和服务依赖分析等。
**目前主流的工具有：**Cat、Zipkin、Pinpoint、SkyWalking
主要架构
SkyWalking 逻辑上分为四部分: 探针, 平台后端, 存储和用户界面。
- skyWalking agent探针 使用Javaagent做字节码植入，无侵入式的收集，并通过HTTP或者gRPC方式发送数据到Skywalking Collector。
- **Skywalking Collector ** 链路数据收集器，对agent传过来的数据进行整合分析处理并落入相关的数据存储中。
- Storage 存储 通过开放的插件化的接口存放 SkyWalking 数据. 你可以选择一个既有的存储系统, 如 ElasticSearch, H2 或 MySQL 集群(Sharding-Sphere 管理),也可以选择自己实现一个存储系统. 当然, 我们非常欢迎你贡献新的存储系统实现。
- UI 一个基于接口高度定制化的Web系统，用户可以可视化查看和管理 SkyWalking 数据。

配置Log4j2
在日志格式中添加 [%traceId] 即可
<?xml version="1.0" encoding="UTF-8"?>
<!--Configuration后面的status，这个用于设置log4j2自身内部的信息输出，可以不设置，当设置成trace时，你会看到log4j2内部各种详细输出-->
<!--monitorInterval：Log4j能够自动检测修改配置 文件和重新配置本身，设置间隔秒数-->
<configuration monitorInterval="5">
<!--日志级别以及优先级排序: OFF > FATAL > ERROR > WARN > INFO > DEBUG > TRACE > ALL -->

下载编译好的8.7.0版本包
使用探针实现日志追踪
启动脚本
启动bin目录下的OapService.bat,Linux启动sh后缀文件
启动Java服务
设置探针启动参数
-javaagent:F:\learn\skywalking\apache-skywalking-apm-bin-es7\agent\skywalking-agent.jar
-Dskywalking.agent.service_name=skywalking-test
-Dskywalking.collector.backend_service=127.0.0.1:11800
若使用命令启动jar需要在-jar指令前指定配置：
java -javaagent:/agent/skywalking-agent.jar -Dskywalking.agent.service_name=skywalking-test
-jar springboot.jar
- 1
- 2
idea中可以在启动类中更改Vm option参数
-javaagent: 指定探针jar包
skywalking.agent.service_name 指定服务名
skywalking.collector.backend_service 设置oap服务地址(同一机器中可省略)
具体配置可查看agent/config/agent.config文件查看
访问服务
可以看到打印的日志中可以看到 TID：追踪id
使用UI
Log4j2日志收集格式：https://skywalking.apache.org/docs/main/v8.7.0/en/setup/service-agent/java-agent/application-toolkit-log4j-2.x/
启动bin目录下的webappservice.bat脚本文件
访问 127.0.0.1:8080
添加grpc日志
<GRPCLogClientAppender name="skyWalking_log">
<PatternLayout pattern="${skyWalking_pattern}"/>
</GRPCLogClientAppender>请求项目
注意：使用后台监控前，需要启动先启动需要监控的服务，默认端口8080，可在webapp/webapp.yml文件中修改端口
启动顺序 Java服务---->oapService.bat---->webappservice.bat
或者Java服务---->startup.bat 因为startup.bat就是启动以上两个脚本
切换存储方式
调整config/application.yml文件
# 默认存储方式h2
storage:
selector: ${SW_STORAGE:h2}
# 调整mysql配置 注意更改，数据库信息
storage:
selector: ${SW_STORAGE:mysql}
mysql:
properties:
jdbcUrl: ${SW_JDBC_URL:"jdbc:mysql://localhost:3306/swtest"}
dataSource.user: ${SW_DATA_SOURCE_USER:root}
dataSource.password: ${SW_DATA_SOURCE_PASSWORD:root}
dataSource.cachePrepStmts: ${SW_DATA_SOURCE_CACHE_PREP_STMTS:true}
dataSource.prepStmtCacheSize: ${SW_DATA_SOURCE_PREP_STMT_CACHE_SQL_SIZE:250}
dataSource.prepStmtCacheSqlLimit: ${SW_DATA_SOURCE_PREP_STMT_CACHE_SQL_LIMIT:2048}
dataSource.useServerPrepStmts: ${SW_DATA_SOURCE_USE_SERVER_PREP_STMTS:true}
metadataQueryMaxSize: ${SW_STORAGE_MYSQL_QUERY_MAX_SIZE:5000}
maxSizeOfArrayColumn: ${SW_STORAGE_MAX_SIZE_OF_ARRAY_COLUMN:20}
numOfSearchableValuesPerTag: ${SW_STORAGE_NUM_OF_SEARCHABLE_VALUES_PER_TAG:2}
需要在oap-libs目录下放入mysql连接驱动的jar包，否则启动报错
下载对应版本：https://mvnrepository.com/artifact/mysql/mysql-connector-java
重新启动startup.bat后mysql会自动创建需要的表
