无法使用Logstash过滤器解析xml输入 [英] can't parse xml input with logstash filter

问题描述

我正在尝试解析以下xml:

Hi I'm trying to parse the following xml :

<msg time='2014-08-04T14:36:02.136+03:00' org_id='oracle' comp_id='rdbms'
 msg_id='opistr_real:953:3971575317' type='NOTIFICATION' group='startup'
 level='16' host_id='linux4_l' host_addr='127.0.0.1'
 pid='8986' version='1'>
 <txt>Starting ORACLE instance (normal)
 </txt>
</msg>

使用此配置:

 input {
   stdin {
    type => "stdin-type"
  }
  }
 filter { multiline {
                       pattern => "^\s|</msg>|^[A-Za-z].*"
                        what => "previous"
                }
                xml {
                        store_xml => "false"
                        source => "message"
                        xpath => [
                                "/msg/@client_id", "msg_client_id",
                                "/msg/@host_id", "msg_host_id",
                                "/msg/@host_addr", "msg_host_addr",
                                "/msg/@level", "msg_level",
                                "/msg/@module", "msg_module",
                                "/msg/@msg_id", "msg_msg_id",
                                "/msg/@pid", "msg_pid",
                                "/msg/@org_id", "msg_org_id",
                                "/msg/@time", "msg_time",
                                "/msg/@level", "msg_level",
                                "/msg/txt/text()","msg_txt"
                        ]
               }
                date {
                        match => [ "msg_time", "ISO8601" ]
                }
                mutate {
                        add_tag => "%{type}"
                }
}
output { elasticsearch { host => localhost } stdout { codec => rubydebug } }

但是当我运行logstash时，出现以下错误:

but when i run logstash I get the following error :

{:timestamp=>"2014-09-04T17:28:39.428000+0300", :message=>"Exception in filterworker", "exception"=>#<NoMethodError: undefined method `split' for ["msg_level", "msg_level"]:Array>, "backtrace"=>["/opt/logstash/lib/logstash/util/accessors.rb:19:in `parse'", "/opt/logstash/lib/logstash/util/accessors.rb:15:in `get'", "/opt/logstash/lib/logstash/util/accessors.rb:59:in `store_path'", "/opt/logstash/lib/logstash/util/accessors.rb:55:in `lookup'", "/opt/logstash/lib/logstash/util/accessors.rb:34:in `get'", "/opt/logstash/lib/logstash/event.rb:127:in `[]'", "/opt/logstash/lib/logstash/filters/xml.rb:117:in `filter'"

推荐答案

我发现我在xpath/msg @ level apper上重复解析两次的问题.

I've found my problem I've duplicated parsing on xpath , /msg@level apper twice .
