SpringBoot使用Graylog日志收集

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:

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:

640?wx_fmt=png

这里默认用户名密码都是admin,进入后如图所示。

640?wx_fmt=png

选择System按钮中的input,录入一个输入源,如图

640?wx_fmt=png

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

640?wx_fmt=png

在Node处选择自己安装的,剩下的就根据需要填写即可,如图

640?wx_fmt=png

保存完成后如图,到这里就已经配置完成了。

640?wx_fmt=png

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>

    <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。
