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

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.ConsoleAppenderlog4j.appender.stdout.Target = System.outlog4j.appender.stdout.layout = org.apache.log4j.PatternLayoutlog4j.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.DailyRollingFileAppenderlog4j.appender.D.File = /Users/KG/Documents/logs/t-server/app.loglog4j.appender.D.Append = truelog4j.appender.D.Threshold = DEBUGlog4j.appender.D.layout = org.apache.log4j.PatternLayoutlog4j.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.ConsoleAppenderlog4j.appender.stdout.Target = System.outlog4j.appender.stdout.layout = org.apache.log4j.PatternLayoutlog4j.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.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 = %-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!!");    }}

运行结果如下:
