3.4 日志采集-gRPC导出Logback日志

一、日志采集

1. 方便系统排查错误以及日志信息筛选

2. 引入坐标

   <dependency>
       <groupId>org.apache.skywalking</groupId>
       <artifactId>apm-toolkit-logback-1.x</artifactId>
       <version>8.15.0</version>
   </dependency>

3. 添加相关配置：

   logback.xml

   <?xml version="1.0" encoding="UTF-8"?>
   <configuration>
       <springProperty name="appName" source="spring.application.name"/>
       <springProperty name="logFile" source="logging.file.name"/>
       <springProperty name="logLevel" source="logging.level.root" defaultValue="info"/>
       <springProperty name="maxFileSize" source="logging.file.max-size" defaultValue="500MB"/>
       <springProperty name="maxHistory" source="logging.file.max-history" defaultValue="60"/>
   
       <!-- 彩色日志格式 -->
       <property name="CONSOLE_LOG_PATTERN"
                 value="${CONSOLE_LOG_PATTERN:-%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(${LOG_LEVEL_PATTERN:-%5p}) %clr(${PID:- }){magenta} %clr(---){faint} %clr([%15.15t]){faint} %clr(%-40.40logger{39}){cyan} %clr(:){faint} %m%n${LOG_EXCEPTION_CONVERSION_WORD:-%wEx}}"/>
       <!-- 彩色日志依赖的渲染类 -->

       <conversionRule conversionWord="wex"

   备注：为了区分，建议命名为logback-spring.xml

   然后再application.yml中进行配置：
