logstash 配置文件 [通过正则匹配两种日志]

[root@ope-elk ~]# cat /home/wx/logstash-6.2.4/config/beats.conf 
input {
  beats {
    port => 5044
  }
}

filter {
        grok{
             match => [
                        "message" , "(^[ ](?<Level>[A-Z]{0,})\s(?<Date>\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2},\d{0,})\s\d{0,}\s.*).*",  "message" , "(?<Level>^[A-Z]{0,})\s(?<Date>\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2},\d{0,})\s\d{0,}\s.*"
                      ]             
             overwrite =>["message"]
        }
        date {
        match => [ "Date", "yyyy-MM-dd HH:mm:ss,SSS" ]
        target => [ "@timestamp" ]
    }
}
