elasticsearch - Logstash/Elasticsearch:geoip.asn值的数字格式异常

Question

尝试解析并在另一个字段中使用geoip.asn值，如下所示:

   geoip {
    default_database_type => "ASN"
    source => "dst"
   }

   mutate {
    add_field => { "[dst_asn]" => "%{[geoip][asn]}" }
    # remove_field => [ "geoip" ]
   }

这是我各自的索引模板字段声明:

"dst_asn": {"type": "integer"},

但是，对于 一些值，我得到以下错误:

[2018-11-07T14:19:17,716][WARN ][logstash.outputs.elasticsearch] Could not index event to Elasticsearch. {:status=>400, :action=>["index", {:_id=>nil, :_index=>"my_index_raw_data-2018.11.07", :_type=>"_doc", :_routing=>nil}, #<LogStash::Event:0x5c30a50a>], :response=>{"index"=>{"_index"=>"my_index_raw_data-2018.11.07", "_type"=>"_doc", "_id"=>"Kcsc7mYBo99I6PWl0CVS", "status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse [dst_asn]", "caused_by"=>{"type"=>"number_format_exception", "reason"=>"For input string: \"%{[geoip][asn]}\""}}}}}

Answer 1

add_field定义不正确，应如下所示:

add_field => { "[dst_asn]" => "%{[geoip][asn]}" }
