logstash解析tomcat的catalina.out日誌字段

在工做中須要在elk中展現tomcat的日誌，對其進行分析，報錯排查及其它定製需求；

下面爲catalina.out日誌樣例，以此爲樣本進行字段的解析；注：能夠看到此段日誌有規律的，由此能夠對其進行解析；

經過在grokdebug上面進行調試，日誌字段能夠解析爲：

%{TIMESTAMP_ISO8601:access_time} %{LOGLEVEL:loglevel} \[%{DATA:exception_info}\] - \<%{MESSAGE:message}\>

注1：將catalina.out的日誌解析爲：日誌時間、日誌級別、異常提示、異常內容

注2：MESSAGE是本身定義的匹配規則，用於匹配任何數據（包括單行和多行）：MESSAGE [\s\S]*

filebeat先讀取catalina.out的日誌，寫入redis中：

filebeat.inputs:
- type: log
  paths:
    - /data/sadv/10.78.3.129/test5.out
  tags: ["sadv"]
  fields:
    type: sadv
  fields_under_root: true
  multiline:
    pattern: '^\d+-\d+-\d+ \d+:\d+:\d+'
    negate: true
    match: after
output.redis:
  hosts: ["10.78.1.181"]
  key: "sadv"
  datatype: list

logstash向redis讀取數據，解析過濾以後寫入elastic中：

input {
    redis {
        host => "10.78.1.181"
        port => 6379
        db => "0"
        data_type => "list"
        key => "sadv"
        type => "sadv"
    }
}
filter {
    mutate {
        remove_field => ["@version","prospector","input","beat","source","offset"]
    }
    grok {
        match => {
            "message" => "%{TIMESTAMP_ISO8601:access_time} %{LOGLEVEL:loglevel} \[%{DATA:exception_info}\] - \<%{MESSAGE:message}\>"
        }
        pattern_definitions => {
            "MESSAGE" => "[\s\S]*"
        }
    }
    date {
        match => [ "access_time","yyyy-MM-dd HH:mm:ss,SSS" ]
    }
    mutate {
        remove_field => ["access_time","[message][0]"]
    }
}
output {
    if [type] == "sadv" {
        if [tags][0] == "sadv" {
            elasticsearch {
                hosts  => ["10.78.1.184:9200","10.78.1.185:9200","10.78.1.188:9200"]
                index  => "%{type}-%{+YYYY.MM.dd}"
            }
            stdout { codec => rubydebug }
        }
    }
}

注：output中的stdout爲調試所用，生產建議刪除
