我正在构建一个ELK设置,它运行良好,但是我正在进入这样一种情况,我希望在处理过程中从系统日志数据中删除某些字段。 logstash 喜欢 remove_field 和; remove_tag 我已经在我的logstash配置文件中定义了它,但它不起作用。

寻找任何尊重和专家建议,纠正配置,使其运行,非常感谢在高级。

我的logstash配置文件:

[root@sandbox-prd~]# cat /etc/logstash/conf.d/syslog.conf
input {
  file {
    path => [ "/data/SYSTEMS/*/messages.log" ]
    start_position => beginning
    sincedb_path => "/dev/null"
    max_open_files => 64000
    type => "sj-syslog"
 }
}

filter {
  if [type] == "sj-syslog" {
    grok {
      match => { "message" => "%{SYSLOGTIMESTAMP:syslog_timestamp } %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" }
      add_field => [ "received_at", "%{@timestamp}" ]
      remove_field => ["@version", "host", "_type", "_index", "_score", "path"]
      remove_tag => ["_grokparsefailure"]
    }
    syslog_pri { }
    date {
      match => [ "syslog_timestamp", "MMM  d HH:mm:ss", "MMM dd HH:mm:ss" ]
  }
 }
}
output {
        if [type] == "sj-syslog" {
        elasticsearch {
                hosts => "sandbox-prd02:9200"
                manage_template => false
                index => "sj-syslog-%{+YYYY.MM.dd}"
                document_type => "messages"
  }
 }
}
