准备工作

建立文件夹，给data文件夹777权限

[root@hao /usr/local/software/elk/logstash]# ll

drwxrwsr-x. 2 root root 66 12月  6 10:12 config
drwxrwxrwx. 4 root root 69 12月  6 10:18 data

只需要建logstash.yml、pipelines.yml、logstash.conf文件

[root@hao /usr/local/software/elk/logstash]# tree
.
├── config
│   ├── jvm.options
│   ├── logstash.yml
│   └── pipelines.yml
├── data

│   ├── queue
│   └── uuid
└── pipeline└── logstash.conf5 directories, 5 files

内容分别为

config.test_and_exit: false
config.reload.automatic: false
http.host: "0.0.0.0" 
xpack.monitoring.elasticsearch.hosts: [ "http://192.168.133.100:9200" ]

input {tcp {mode => "server"host => "0.0.0.0"port => 5044codec => json_lines}
}
filter{

output {elasticsearch {hosts => ["192.168.133.100:9200"]       #elasticsearch的ip地址index => "elk_logstash"                          #索引名称}stdout { codec => rubydebug }
}

创建容器

docker run -it \
--name logstash \
--privileged \
-p 5044:5044 \
-p 9600:9600 \
--network wn_docker_net \
--ip 172.18.12.72 \

查看日志是否启动成功，没报错就可以

SpringBoot整合logstash

引入依赖

<dependency><groupId>net.logstash.logback</groupId><artifactId>logstash-logback-encoder</artifactId><version>7.3</version>
</dependency>

配置spring-logback.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!-- 日志级别从低到高分为TRACE < DEBUG < INFO < WARN < ERROR < FATAL，如果设置为WARN，则低于WARN的信息都不会输出 -->
<!-- scan:当此属性设置为true时，配置文档如果发生改变，将会被重新加载，默认值为true -->
<!-- scanPeriod:设置监测配置文档是否有修改的时间间隔，如果没有给出时间单位，默认单位是毫秒。当scan为true时，此属性生效。默认的时间间隔为1分钟。 -->
<!-- debug:当此属性设置为true时，将打印出logback内部日志信息，实时查看logback运行状态。默认值为false。 -->

主要配置35行的ip地址和端口

使日志插入logstash

只需要使用lombok依赖的@Slf4j注解，把要放入日志的东西加进去即可

package com.wnhz.smart.es.controller;import com.wnhz.smart.common.http.ResponseResult;
import com.wnhz.smart.es.doc.BookTabDoc;
import com.wnhz.smart.es.service.IBookTabDocService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.util.List;/*** @author Hao* @date 2023-12-06 10:40*/
@RestController
@RequestMapping("/api/query")
@Slf4j
public class QueryController {@Autowiredprivate IBookTabDocService iBookTabDocService;@GetMapping("/test")public ResponseResult<List<BookTabDoc>> test() {List<BookTabDoc> allBooks = iBookTabDocService.getAllBooks();log.debug("从es中查询到的所有数据：{}", allBooks.subList(0, 1000));return ResponseResult.ok(allBooks.subList(0, 3));}
}

这样所有的数据就会自动插入logstash

配置kibana

进入网页http://192.168.133.100:5601/app/dev_tools#/console，创建索引

进入http://192.168.133.100:5601/app/management（原网页点击Stack Management），点击index Patterns创建匹配模式，输入logstash.conf文件中的index后面的名字，这里是elk_logstash

查询方法：message 内容

日志的条数查询错误解决

当日志的条数太多会出现下面的错误警告

The length [1417761] of field [message] in doc[20]/index[elk_logstash] exceeds the [index.highlight.max_analyzed_offset] limit [1000000]. To avoid this error, set the query parameter [max_analyzed_offset] to a value less than index setting [1000000] and this will tolerate long field values by truncating them.

解决方法

解决方案，使用任意一个可以put http值和参数的工具，对目标主机上部署的es进行put命令配置：

！！！注意是put请求，请求地址和body参数分别为：

http://localhost:9200/_all/_settings?preserve_existing=true

{"index.highlight.max_analyzed_offset" : "999999999"
}

返回结果这样就是成功了

{
"acknowledged": true
}

数的工具，对目标主机上部署的es进行put命令配置：

！！！注意是put请求，请求地址和body参数分别为：

http://localhost:9200/_all/_settings?preserve_existing=true

{"index.highlight.max_analyzed_offset" : "999999999"
