Question

我正在尝试按照以下链接中的指南进行操作：

http://www.viaboxx.de/code/easily-generate-live-heatmaps-for-geolocations-with-elk/#codesyntax_1

第一次它对我来说很好，但是当我现在尝试它时，它在我尝试加载csv数据的步骤中给出了以下错误。我执行的命令是：

cat test.csv | /opt/logstash/bin/logstash -f geostore.conf

我收到以下错误：

Settings: Default pipeline workers: 2
Pipeline main started
Error parsing csv {:field=>"message", :source=>"", :exception=>#<NoMethodError: undefined method `each_index' for nil:NilClass>, :level=>:warn}
Pipeline main has been shutdown
stopping pipeline {:id=>"main"}

你能帮忙!!!我花了几天时间试图找出答案。

编辑添加geostore.conf：

 input { stdin {} } 
    filter { # Step 1, drop the csv header line 
       if [message] =~ /^#/ { 
          drop {} 
        } # Step 2, split latitude and longitude 
        csv { 
          separator => ',' 
          columns => [ 'lat', 'lon' ] } 
           # Step 3 # move lat and lon into location object # for defined geo_point type in ES 
        mutate { 
             rename => [ "lat", "[location][lat]", "lon", "[location][lon]" ] 
         } 
       } 
    output { 
       elasticsearch {
         hosts => 'localhost' 
         index => 'geostore' 
         document_type => "locality" 
         flush_size => 1000 
      } 
    }

我已经改变了输出部分：

output {
  elasticsearch {
    hosts => 'localhost'
    index => 'geostore'
    document_type  => "locality"
    flush_size => 1000
  }

到这个

output {
  elasticsearch {
    hosts => 'localhost'
    index => 'geostore'
    document_type  => "locality"
    flush_size => 1000
    stdout {}
  }

现在我收到了更详细的错误消息：

    fetched an invalid config {:config=>"input {\n    stdin {}\n}\nfilter {\n  #

index => 'geostore'\n    document_type  => \"locality\"\n    flush_size => 
1000\n    stdout ", :level=>:error}

无法理解为什么它第一次起作用。

Answer 1

Hopefull，这也有助于其他人。

我从命令行删除了模式：

curl -XDELETE 'localhost:9200/geostore?pretty';

然后去kibana从那里删除它。如下重新加载模式，它工作。

    curl -XPUT 'http://localhost:9200/geostore'

curl -XPUT 'http://localhost:9200/geostore/_mapping/locality' -d '
{
   "locality" : {
       "properties" : {
              "location" : {
                  "type" : "geo_point",
                  "geohash_prefix":     true,
                  "geohash_precision":  "1km"
              }
          }
       }
}'

cat test.csv | /opt/logstash/bin/logstash -f geostore.conf

启动logstash需要几秒钟，解析输入并将结果存储到Elasticsearch中。

现在我们有了Elasticsearch中的数据，让我们转到Kibana 4.登录Kibana后，你需要将索引添加到Kibana。

转到：设置 - ＆gt;指数 - ＆gt;添加新 - ＆gt;在索引名称字段中写下“geostore”。

添加索引后，您将看到索引文档中的所有字段，尤其是您应该检查属性位置是否归类为geo_point。

以下链接详细介绍了整个过程。

无法将数据加载到logstash
