鍵值對logstash陣列

Question

我使用logstash，我想知道是否有處理以下方式：

使用XML過濾器我能提取屬性字段中

<?xml version="1.0"?> 
<event logger="RemoteEventReceiver1" timestamp="2016-07-21T12:39:04.0607421-05:00" level="DEBUG" thread="26" domain="/LM/W3SVC/2/ROOT-1-131135962764935573" username="TOOTHLESS\dvdp4"> 
    <message>Test nessage</message> 
    <properties> 
     <data name="log4net:HostName" value="Toothless"/> 
     <data name="log4net:Customer" value="Bob"/> 
    </properties> 
</event> 

，看起來像這樣

"properties" => [ 
    [0] { 
     "data" => [ 
      [0] { 
       "name" => "HostName", 
       "value" => "Toothless" 
      }, 
      [1] { 
       "name" => "Customer", 
       "value" => "Bob" 
      } 
     ] 
    } 
] 

我怎樣才能將其轉換爲這個？

「propertiesParsed」 => { 
    「HostName」 => 「Toothless」, 
    「Customer」 => 「Bob」 
    } 

* UPDATE ADDING CONFIG文件和數據文件*

input { 
    file { 
     type => "log4net" 
     path => ["D:/temp/MR4SPO.log"] 
     start_position => "beginning" 
     sincedb_path => "nul" 
    } 
} 
filter 
{ 
    mutate { 
     # remove xml prefices in the message field 
     gsub => [ "message", "log4net:", "" ] 
    } 

    xml { 
     source => "message" 
     target => "log4net" 
     add_field => { 
      log4net_message => "%{[log4net][message]}" 
      # "[log4net][messagetest]" => [log4net][message] 
      # xxx => "%{[log4net][properties][0][data]}" 
     }  
     remove_field => "message" 
    } 

    # get json message from log4net 
    if [log4net_message] =~ "^LS:\s{" { 
     ruby { code => "event['log4net_message'] = event['log4net_message'][3..-1]" } 
     json { 
      source => "log4net_message" 
      # target => "log4net_json" 
     } 
     mutate { 
      add_field => { forMQ => true } 
     } 
    } 

    mutate { 
     remove_field => "log4net_message" 
    } 
} 

# output logs to console and to elasticsearch 
output { 
    if [forMQ] { 
     stdout { codec => rubydebug } 
    } 

    # elasticsearch { hosts => ["localhost:9200"] } 

} 

* DATA FILE *

Answer 1

您可以添加ruby過濾：

... 
ruby { 
    code => " 
    event['propertiesParsed'] = {} 
    for value in event['log4net']['properties'] 
     for data in value['data'] 
      event['propertiesParsed'][data['name']] = data['value'] 
     end 
    end 
    " 
} 
...
