ELK菜鸟手记 (四) - 利用filebeat和不同端口把不同服务器上的log4j日志传输到同一台ELK服务器

日期：2017-05-25点击：507收藏

1. 问题描述

我们需要将不同服务器(如Web Server)上的log4j日志传输到同一台ELK服务器，介于公司服务器资源紧张(^_^)

2. 我们需要用到filebeat

什么是filebeat?

filebeat被用来ship events,即把一台服务器上的文件日志通过socket的方式，传输到远程的ELK。

可以传输到logstash,也可以直接传输到elasticsearch。

3. 我们这里讲解如何传输到远程的logstash，然后再由elasticsearch讲数据传输到kibana展示

3-1）首先你要在你的本地测试机器上安装filebeat

以下是下载路径：

https://www.elastic.co/downloads/beats/filebeat

3-2) 其次你应该配置你的filebeat.xml

filebeat.prospectors: - input_type: log # Paths that should be crawled and fetched. Glob based paths. paths: - /Users/KG/Documents/logs/t-server/*.log #----------------------------- Logstash output -------------------------------- output.logstash: # The Logstash hosts hosts: ["xx.xx.xx.xx:5000"]

3-3) 启动filebeat

需要先给配置文件加权限

chown root filebeat.yml

然后启动

sudo ./filebeat -e -c filebeat.yml &

3-4) 配置远程的logstash并启动

log4j_filebeat.conf

input{ beats { port => 5000 } } output{ stdout{ codec => rubydebug } elasticsearch { hosts => "localhost:9200" index => "t-server-%{+YYYY.MM.dd}" document_type => "log4j_type" user => your-username password => your-password } }

启动：

./bin/logstash -f config/log4j_fliebeat.conf &

3-5) Java客户端日志配置和程序

log4j.properties

### 设置### log4j.rootLogger = debug,stdout,D ### 输出信息到控制抬 ### log4j.appender.stdout = org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target = System.out log4j.appender.stdout.layout = org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n ### 输出DEBUG 级别以上的日志到=/Users/bee/Documents/elk/log4j/debug.log### log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = /Users/KG/Documents/logs/t-server/app.log log4j.appender.D.Append = true log4j.appender.D.Threshold = DEBUG log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

Java API

package org.genesis.arena.elk; import org.apache.log4j.Logger; /** * Created by KG on 17/3/27. */ public class ElkLog4jTest { private static final Logger logger = Logger.getLogger(ElkLog4jTest.class); public static void main(String[] args) throws Exception { logger.debug("最新的日志!!"); } }

在logstash看到结果如下:

在kibana看到结果如下：

同理，我们使用另一个端口启动另外一个logstash后台进程

logstash配置文件如下：

log4j_fliebeat2.conf

input{ beats { port => 5001 } } output{ stdout{ codec => rubydebug } elasticsearch { hosts => "localhost:9200" index => "t-yxc-finance-%{+YYYY.MM.dd}" document_type => "log4j_type" user => your-username password => your-password } }

启动：

./bin/logstash -f config/log4j_fliebeat2.conf &

filebeat.yml

filebeat.prospectors: # Each - is a prospector. Most options can be set at the prospector level, so # you can use different prospectors for various configurations. # Below are the prospector specific configurations. - input_type: log # Paths that should be crawled and fetched. Glob based paths. paths: - /Users/KG/Documents/logs/t-yxc-finance/*.log #----------------------------- Logstash output -------------------------------- output.logstash: # The Logstash hosts hosts: ["xx.xx.xx.xx:5001"]

客户端配置文件和代码：

### 设置### log4j.rootLogger = debug,stdout,D ### 输出信息到控制抬 ### log4j.appender.stdout = org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target = System.out log4j.appender.stdout.layout = org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n ### 输出DEBUG 级别以上的日志到=/Users/bee/Documents/elk/log4j/debug.log### log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = /Users/KG/Documents/logs/t-yxc-finance/app.log log4j.appender.D.Append = true log4j.appender.D.Threshold = DEBUG log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %t:%r ] - [ %p ] %m%n

package org.genesis.arena.elk; import org.apache.log4j.Logger; /** * Created by KG on 17/3/27. */ public class ElkLog4jTest { private static final Logger logger = Logger.getLogger(ElkLog4jTest.class); public static void main(String[] args) throws Exception { logger.debug("另外一台服务器,最新的日志!!"); } }
