篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了如何利用filebeat把不同服务器上的log4j日志传输到同一台ELK服务器相关的知识,希望对你有一定的参考价值。
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: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.ConsoleAppenderlog4j.appender.stdout.Target = System.outlog4j.appender.stdout.layout = org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern = [%-5p] %dyyyy-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 = %-dyyyy-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.ConsoleAppenderlog4j.appender.stdout.Target = System.outlog4j.appender.stdout.layout = org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern = [%-5p] %dyyyy-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.DailyRollingFileAppenderlog4j.appender.D.File = /Users/KG/Documents/logs/t-yxc-finance/app.loglog4j.appender.D.Append = truelog4j.appender.D.Threshold = DEBUGlog4j.appender.D.layout = org.apache.log4j.PatternLayoutlog4j.appender.D.layout.ConversionPattern = %-dyyyy-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!!");
运行结果如下:
