这篇文章主要介绍springboot整合elk.
Elasticsearch是个开源分布式搜索引擎,它的特点有:分布式,零配置,自动发现,索引自动分片,索引副本机制,restful风格接口,多数据源,自动搜索负载等。
Logstash是一个完全开源的工具,他可以对你的日志进行收集、过滤,并将其存储供以后使用(如,搜索)。
Kibana 也是一个开源和免费的工具,它Kibana可以为 Logstash 和 ElasticSearch 提供的日志分析友好的 Web 界面,可以帮助您汇总、分析和搜索重要数据日志。
elk下载地址:https://www.elastic.co/downloads/
建议在 linux上运行,elk在windows上支持得不好,另外需要jdk1.8 的支持,需要提前安装好jdk.
下载完之后: 安装,以logstash为栗子:
cd /usr/local/
mkdir logstash
tar -zxvf logstash-5.3.2.tar.gz
mv logstash-5.3.2 /usr/local/logstash
打开Elasticsearch的配置文件:
vim config/elasticsearch.yml
修改配置:
network.host=localhost
network.port=9200
它默认就是这个配置,没有特殊要求,在本地不需要修改。
启动Elasticsearch
./bin/elasticsearch
启动成功,访问localhost:9200,网页显示:
{
"name" : "56IrTCM",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "e4ja7vS2TIKI1BsggEAa6Q",
"version" : { "number" : "5.2.2", "build_hash" : "f9d9b74", "build_date" : "2017-02-24T17:26:45.835Z", "build_snapshot" : false, "lucene_version" : "6.4.1" },
"tagline" : "You Know, for Search" }
在 logstash的主目录下:
vim config/log4j_to_es.conf
修改 log4j_to_es.conf 如下:
input {
log4j {
mode => "server"
host => "localhost"
port => 4560
}
}
filter {
#Only matched data are send to output.
}
output {
elasticsearch {
action => "index" #The operation on ES
hosts => "localhost:9200" #ElasticSearch host, can be array.
index => "applog" #The index to write data to.
}
}
修改完配置后启动:
./bin/logstash -f config/log4j_to_es.conf
终端显示如下:
访问localhost:9600
{"host":"Pc-20130412.local","version":"5.3.2","http_address":"127.0.0.1:9600","id":"e6bb985c-c688-49a4-
a55b-4d362bb4136f","name":"Pc-20130412.local","build_date":
"2017-04-24T16:32:22Z","build_sha":"242159a5eea55fe213fe5c8
52d36455e24252c82","build_snapshot":false}
证明logstash启动成功。
到kibana的安装目录:
./bin/kibana
默认配置即可。
访问localhost:5601,网页显示:
证明启动成功。

# for package com.demo.elk, log would be sent to socket appender.
log4j.logger.com.forezp=DEBUG, socket

@SpringBootTest
public class SpringbootElkApplicationTests {
@Test
public void contextLoads() {
}
private Logger logger = Logger.getLogger(getClass());
@Test
public void test() throws Exception {
for(int i=0;i<100;i++) {
logger.info("输出info ");
logger.debug("输出debug+skkkw嗡嗡嗡kw");
logger.error("输出error 嗡嗡嗡我");
}
}
}
