Spring Boot学习笔记七：整合ELK

前面我们已经在Windows搭建好了ELK，没看过的朋友可以看一下我的上一篇文章
https://www.jianshu.com/p/b783688f637d
现在我们开始试着把ELK整合到项目中实现日志的分析

1.首先我们把Logstash的conf配置文件改成

input {
    tcp {  
        host => "localhost"    ##安装logstash的ip
        port =>  9601          ##设置logstash的端口
        mode => "server"  
        tags => ["tags"]  
 
        codec => json_lines      ##格式json    
    }  
 
} 
 
output {
    elasticsearch {
        action => "index"
        hosts => "127.0.0.1:9200"         #e#s的ip和端口（本次logstash和es是同一个服务器）
        index => "applog"                 ##es的index名称
    }
    stdout { codec => rubydebug}
}

接着重新启动一下

2.去我们的Spring Boot项目里添加依赖

        <!--ELK-->
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-core</artifactId>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
        </dependency>
        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-access</artifactId>
        </dependency>
        <dependency>
            <groupId>net.logstash.logback</groupId>
            <artifactId>logstash-logback-encoder</artifactId>
            <version>5.1</version>
        </dependency>

3.在resources中添加配置文件logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml" />

    <appender name="LOGSTASH" class="net.logstash.logback.appender.LogstashTcpSocketAppender">
        <!--这里必须和logstash配置文件中input -tcp 中的host 和 port一致-->
        <destination>localhost:9601</destination>
        <!-- 日志输出编码 -->
        <encoder charset="UTF-8"
                 class="net.logstash.logback.encoder.LoggingEventCompositeJsonEncoder">
            <providers>
                <timestamp>
                    <timeZone>UTC</timeZone>
                </timestamp>
                <pattern>
                    <pattern>
                        {
                        "logLevel": "%level",
                        "serviceName": "${springAppName:-}",
                        "pid": "${PID:-}",
                        "thread": "%thread",
                        "class": "%logger{40}",
                        "rest": "%message"
                        }
                    </pattern>
                </pattern>
            </providers>
        </encoder>
    </appender>

    <root level="INFO">
        <appender-ref ref="LOGSTASH" />
        <appender-ref ref="CONSOLE" />
    </root>

</configuration>

4.最后我们添加测试类进行测试

   private final static Logger logger = LoggerFactory.getLogger(TextController.class );

    @RequestMapping("/textElk")
    public String textElk(){
        logger.info("===================textElk");
        logger.info("===================开始测试");
        return "ok";
    }

把项目跑起来

5.进入到Kibana中查看日志信息
首先去management中找到Index patterns然后点击Create index pattern

填写完以后点击Next step

此处选择"@timestamp"后确认
最后在Discover中查看
