​

新增一个配置文件 first-pipeline.conf

配置说明 从 filebeat 中收集日志 然后输出到标准输出和 elasticcsearch

input{

    beats{

        port => "5044"

    }

}

filter {

    # grok {

    # match => { "message" => "%{IP:client} %{WORD:method} %{URIPATHPARAM:request} %    {NUMBER:bytes} %{NUMBER:duration}" }

    # }

    json {

        source => "message" #要解析的字段名

        target => "msg_json" #解析后的存储字段，默认和message同级别

    }

}

output {

    stdout{

        codec => rubydebug

    }

    elasticsearch {

        hosts => [ "localhost:9200" ]

    }

}
​

检查并启动

./bin/logstash -f config/first-pipeline.conf --config.test_and_exit
​

自动加载配置

./bin/logstash -f config/first-pipeline.conf --config.reload.automatic
​

grok 插件  适合系统日志

日志示例

55.3.244.1 GET /index.html 15824 0.043

#filter

grok {

 match => { "message" => "%{IP:client} %{WORD:method} %{URIPATHPARAM:request} %{NUMBER:bytes} %{NUMBER:duration}" }

}
​

json 插件

json {

    source => "message" #要解析的字段名

    target => "msg_json" #解析后的存储字段，默认和message同级别

}
​

nginx 的过滤器

grok {

match => { "message" => "%{IP:client} - - \[%{HTTPDATE:logdate}\] \"%{WORD:verb} %{URIPATHPARAM:request} HTTP/%{NUMBER:httpversion}\" %{NUMBER:http_status_code} %{NUMBER:bytes} \"%{NOTSPACE:ref}\" \"%{DATA:user_agent}\"" }

}

date {

match => ["logdate", "dd/MMM/yyyy:HH:mm:ss Z"]

target => "@timestamp"

}

kv {

source => "request"

field_split => "&?"

value_split => "="

}

urldecode {

all_fields => true

}
​

start_position

从哪个位置读取文件数据，默认从尾部，值为：end
如果要导入历史数据则设置成：beginning 

input {

    file {

        path => ["/opt/flights2.csv”]

        start_position => “beginning”

     }

}
