SpringBoot使用Graylog日志收集

别来无恙 提交于 2019-11-30 02:13:19

本文介绍SpringBoot如何使用Graylog日志收集。

1.Graylog介绍

Graylog是一个生产级别的日志收集系统,集成Mongo和Elasticsearch进行日志收集。其中Mongo用于存储Graylog的元数据信息和配置信息,ElasticSearch用于存储数据。

架构图如下:

生产环境配置图如下:

2.安装Graylog

在官方文档上推荐了很多种安装的方式,这里以docker-compose的方式为例,进行安装Graylog,mongo,elasticsearch。

docker-compose.yml内容如下(这里是在官网的基础上改了一下):

version: '2' services:   # MongoDB: https://hub.docker.com/_/mongo/   mongodb:     image: mongo:3   # Elasticsearch: https://www.elastic.co/guide/en/elasticsearch/reference/6.6/docker.html   elasticsearch:     image: docker.elastic.co/elasticsearch/elasticsearch-oss:6.6.1     environment:       - http.host=0.0.0.0       - transport.host=localhost       - network.host=0.0.0.0       - "ES_JAVA_OPTS=-Xms256m -Xmx256m"     ulimits:       memlock:         soft: -1         hard: -1     mem_limit: 512m   # Graylog: https://hub.docker.com/r/graylog/graylog/   graylog:     image: graylog/graylog:3.0     environment:       # CHANGE ME (must be at least 16 characters)!       - GRAYLOG_PASSWORD_SECRET=somepasswordpepper       # Password: admin       - GRAYLOG_ROOT_PASSWORD_SHA2=8c6976e5b5410415bde908bd4dee15dfb167a9c873fc4bb8a81f6f2ab448a918       - GRAYLOG_HTTP_EXTERNAL_URI=http://106.13.35.42:9000/     links:       - mongodb:mongo       - elasticsearch     depends_on:       - mongodb       - elasticsearch     ports:       # Graylog web interface and REST API       - 9000:9000       # Syslog TCP       - 1514:1514       # Syslog UDP       - 1514:1514/udp       # GELF TCP       - 12201:12201       # GELF UDP       - 12201:12201/udp 

其中106.13.35.42是我的外网ip,本地服务使用127.0.0.1即可。

其他方式可以查看官方文档,https://docs.graylog.org/en/3.0/pages/installation.html

3.配置Graylog

在浏览器访问http://ip:9000,如图:

这里默认用户名密码都是admin,进入后如图所示。

选择System按钮中的input,录入一个输入源,如图

这里以GELF UDP为例,在图中位置选择GELF UDP,选择完成后点击Launch new input,如图

在Node处选择自己安装的,剩下的就根据需要填写即可,如图

保存完成后如图,到这里就已经配置完成了。

4.SpringBoot日志输出到Graylog

这里分别举例Logback日志和Log4j2日志。

4.1 Logback日志

这里使用的logback-gelf向Graylog输出日志,在github上有对logback-gelf的详细使用介绍,这里只是简单举例。Github地址:https://github.com/osiegmar/logback-gelf

新建项目,加入logback-gelf依赖,pom文件如下:

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">     <modelVersion>4.0.0</modelVersion>     <parent>         <groupId>org.springframework.boot</groupId>         <artifactId>spring-boot-starter-parent</artifactId>         <version>2.1.4.RELEASE</version>         <relativePath/> <!-- lookup parent from repository -->     </parent>     <groupId>com.dalaoyang</groupId>     <artifactId>springboot2_graylog</artifactId>     <version>0.0.1-SNAPSHOT</version>     <name>springboot2_graylog</name>     <description>springboot2_graylog</description>      <properties>         <java.version>1.8</java.version>     </properties>      <dependencies>         <dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter-web</artifactId>         </dependency>          <dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter-test</artifactId>             <scope>test</scope>         </dependency>          <dependency>             <groupId>de.siegmar</groupId>             <artifactId>logback-gelf</artifactId>             <version>2.0.0</version>         </dependency>     </dependencies>      <build>         <plugins>             <plugin>                 <groupId>org.springframework.boot</groupId>                 <artifactId>spring-boot-maven-plugin</artifactId>             </plugin>         </plugins>     </build>  </project>  

加入logback日志配置,新建logback-spring.xml,内容如下:

<configuration>      <conversionRule conversionWord="clr" converterClass="org.springframework.boot.logging.logback.ColorConverter" />     <conversionRule conversionWord="wex" converterClass="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter" />     <conversionRule conversionWord="wEx" converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter" />     <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}}"/>      <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">         <encoder>             <pattern>${CONSOLE_LOG_PATTERN}</pattern>             <charset>UTF-8</charset>         </encoder>     </appender>      <appender name="GELF" class="de.siegmar.logbackgelf.GelfUdpAppender">         <graylogHost>106.13.35.42</graylogHost>         <graylogPort>12201</graylogPort>     </appender>      <!-- 控制台输出日志级别 -->     <root level="info">         <appender-ref ref="GELF" />         <appender-ref ref="STDOUT" />     </root>   </configuration>  

启动项目,当前项目端口是8081,查看Graylog控制台如图:

4.2 Log4j2日志

log4j2日志使用的是log4j2-gelf依赖,github上面也有对应的介绍,pom文件如下:

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">     <modelVersion>4.0.0</modelVersion>     <parent>         <groupId>org.springframework.boot</groupId>         <artifactId>spring-boot-starter-parent</artifactId>         <version>2.1.4.RELEASE</version>         <relativePath/> <!-- lookup parent from repository -->     </parent>     <groupId>com.dalaoyang</groupId>     <artifactId>springboot2_graylog_log4j</artifactId>     <version>0.0.1-SNAPSHOT</version>     <name>springboot2_graylog_log4j</name>     <description>springboot2_graylog_log4j</description>      <properties>         <java.version>1.8</java.version>     </properties>      <dependencies>         <dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter-web</artifactId>         </dependency>          <dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter-test</artifactId>             <scope>test</scope>         </dependency>         <dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter</artifactId>             <exclusions>                 <exclusion>                     <artifactId>spring-boot-starter-logging</artifactId>                     <groupId>org.springframework.boot</groupId>                 </exclusion>             </exclusions>         </dependency>         <dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter-log4j2</artifactId>         </dependency>          <dependency>             <groupId>org.graylog2.log4j2</groupId>             <artifactId>log4j2-gelf</artifactId>             <version>1.3.1</version>         </dependency>      </dependencies>      <build>         <plugins>             <plugin>                 <groupId>org.springframework.boot</groupId>                 <artifactId>spring-boot-maven-plugin</artifactId>             </plugin>         </plugins>     </build>  </project> 

创建log4j2-spring.xml进行配置输出日志信息,如下:

<?xml version="1.0" encoding="UTF-8"?> <Configuration status="OFF" packages="org.graylog2.log4j2">     <Properties>         <Property name="LOG_PATTERN">%d{yyyy-MM-dd HH:mm:ss:SSS} - %-5level  - %pid - %t - %c{1.}:%L - %m%n</Property>     </Properties>     <Appenders>         <Console name="Console" target="SYSTEM_OUT" follow="true">             <ThresholdFilter level="trace" onMatch="ACCEPT" onMismatch="DENY" />             <PatternLayout pattern="${LOG_PATTERN}"/>         </Console>         <GELF name="gelfAppender" server="106.13.35.42" port="12201" hostName="appserver01.example.com">             <PatternLayout pattern="%logger{36} - %msg%n"/>             <Filters>                 <Filter type="MarkerFilter" marker="FLOW" onMatch="DENY" onMismatch="NEUTRAL"/>                 <Filter type="MarkerFilter" marker="EXCEPTION" onMatch="DENY" onMismatch="ACCEPT"/>             </Filters>             <!-- Additional fields -->             <KeyValuePair key="foo" value="bar"/>             <KeyValuePair key="jvm" value="${java:vm}"/>         </GELF>     </Appenders>     <Loggers>         <Root level="info">             <AppenderRef ref="gelfAppender"/>             <AppenderRef ref="Console"/>         </Root>     </Loggers> </Configuration> 

这个项目使用的端口号是8888,可以在日志中清晰的看到。

5. ELK vs Graylog

这里仅以日志收集为例,简单说一下二者之间的选择,我个人的建议就是取决于现有技术栈,比如现在就有现成的Mongodb,那么选择Graylog可以节省不少成本,ELK类似,不要盲目的追求技术而选择。
