修改application.yml中的日志配置

#日志配置
logging:
  config: classpath:logback-default.xml # 配置logstash.xml

项目工程改造
将原本使用logService手动插入es的地方，修改为logstash收集方式

5.编写logstash配置脚本（ruby语言）

6.启动logstash

# 我这边将自己写的配置文件均放在conf包中，与logstash自带配置进行区分

nohup ./logstash -f ../conf/structed-collection-log.conf  -w 10 -l /opt/module/weather-collect/log/logstash.log &
# 后台启动并将logstash 日志放到项目目录下的log/logstash.log 包中

springboot项目线上部署命令如下：

nohup java -jar ....jar >/dev/null 2>&1 &

下面是自己搭建本地环境进行演示

ES

（搭建本地es环境）

#修改配置文件 

vim conf/elasticsearch.yml 

network.host: 0.0.0.0 #设置ip地址，任意网络均可访问 

\#说明：在Elasticsearch中如果，network.host不是localhost或者127.0.0.1的话，就会认为是生产环境， 

会对环境的要求比较高，我们的测试环境不一定能够满足，一般情况下需要修改2处配置，如下： 

\#1：修改jvm启动参数 

vim conf/jvm.options 

-Xms128m #根据自己机器情况修改 

-Xmx128m 

\#2：一个进程在VMAs(虚拟内存区域)创建内存映射最大数量 

vim /etc/sysctl.conf 

vm.max_map_count=655360 

sysctl -p #配置生效 

\#启动ES服务 

su - elsearch 

cd bin 

./elasticsearch 或 ./elasticsearch -d #后台启动 

#启动出错，环境：Centos6 
[1]: max file descriptors [4096] for elasticsearch process is too low, increase to at least [65536] 
#解决：切换到root用户，编辑limits.conf 添加类似如下内容 vi /etc/security/limits.conf 1234

[2]: max number of threads [1024] for user [elsearch] is too low, increase to at least [4096]
#解决：切换到root用户，进入limits.d目录下修改配置文件。 
vi /etc/security/limits.d/90-nproc.conf
#修改如下内容： * 
soft nproc 1024
#修改为 
soft nproc 4096 
[3]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk 
#解决：Centos6不支持SecComp，而ES5.2.0默认bootstrap.system_call_filter为true 
vim config/elasticsearch.yml 
#添加： 
bootstrap.system_call_filter: false

Logstash

步驟一： input-tcp方式無filter

# tcp-plug.conf

input {
  tcp {
    mode => "server"
    host => "0.0.0.0"
    port => 5600
  }
}
output{
    elasticsearch {
        hosts => "http://192.168.32.10:9200"
        index => "structed-collection-success"
       }

 }

未加 filter 输出到es中的格式如下：注意message格式

 { 
       "_index": "structed-collection-success",
       "_type": "doc",
       "_id": "8KnuYHIBPM8qiYY-YIOV",
       "_score": 1,
       "_source": { 
           
          "host": "192.168.32.5",
          "message": "      {\"dataCount\":123,\"dataSize\":20.5,\"endTime\":1590735336414,\"latestTimestamp\":1590735336414,\"productId\":\"test22222\",\"useTimeLength\":410}",
          "@timestamp": "2020-05-29T06:55:36.414Z",
          "@version": "1",
          "port": 58959
        }
     }

步骤二：添加filter

filter {
  json {
     source => "message"
 }
}
### 格式如下
 { - 
        "_index": "structed-collection-success",
        "_type": "doc",
        "_id": "Eqn0YHIBPM8qiYY-YIQA",
        "_score": 1,
        "_source": { - 
          "host": "192.168.32.5",
          "@timestamp": "2020-05-29T07:02:09.498Z",
          "dataCount": 123,
          "endTime": 1590735729498,
          "productId": "test22222",
          "@version": "1",
          "message": "{\"dataCount\":123,\"dataSize\":20.5,\"endTime\":1590735729498,\"latestTimestamp\":1590735729498,\"productId\":\"test22222\",\"useTimeLength\":410}",
          "dataSize": 20.5,
          "useTimeLength": 410,
          "port": 59474,
          "latestTimestamp": 1590735729498
        }

剔除message后的配置格式如下

input {
  tcp {
    mode => "server"
    host => "0.0.0.0"
    port => 5600
    codec => json
  }
}

 filter {
  json {
     source => "message"
     remove_field => ["message","port","host"]
 }
}

output{
    elasticsearch {
        hosts => "http://192.168.32.10:9200"
        index => "structed-collection-success"
       }

}

json格式如下：

  { - 
        "_index": "structed-collection-success",
        "_type": "doc",
        "_id": "v6kHYXIBPM8qiYY-R4SF",
        "_score": 1,
        "_source": { - 
          "@timestamp": "2020-05-29T07:22:48.348Z",
          "productId": "test33333",
          "endTime": 1590736968348,
          "dataCount": 123,
          "dataSize": 20.5,
          "latestTimestamp": 1590736968348,
          "@version": "1",
          "useTimeLength": 410
        }
      }

ES-cerebro 常用查询

ELK：通常是指ES + Logstash + Kibana 咱们这里根据线上使用的ES情况，选择了cerebro替换Kibana

term 精准匹配查询

{
    "query" : { 
        "term" : {
            "@timestamp" : "2020-05-29T13:09:19.099Z"
            }
        
    }
    
}

{
    "query" : { 
        "terms" : {
            "@timestamp" : ["2020-05-29T13:09:19.099Z","2020-05-28T11:21:14.001Z"]
            }
        }
  }

range查询时间范围

{
    "query":{
        "bool":{
            "filter":{
                "range":{
                    "invokeTime":{
                        "gt":"1592424431470",
                        "lt":"1592424431949"
                    }
                }
            }
        }
    }
}

简单match 匹配

{
    "query":{
        "match":{
            "reason":"重复推送"
        }
    }
}
