我想知道kv过滤器中递归函数的用法。我正在使用一个csv文件。我使用logstash将文件上传到ES。从此链接https://www.elastic.co/guide/en/logstash/current/plugins-filters-kv.html#plugins-filters-kv-recursive
阅读指南之后我知道它复制了键/值对,并将其存储在单独的键中。但是我无法获得有关过滤器的其他信息或示例。我在logstash配置文件中添加了递归行。没有变化。 它是使用值(键值对)复制字段,还是此函数在做什么?
这是我通过logstash传递的示例csv文件数据:
"host" => "smackcoders",
"Driveline" => "Four-wheel drive",
"Make" => "Jeep",
"Width" => "79",
"Torque" => "260",
"Year" => "2012",
"Horsepower" => "285",
"City_mpg" => "17",
"Height" => "34",
"Classification" => "Manual,Transmission",
"Model_Year" => "2012 Jeep Wrangler",
"Number_of_Forward_Gears" => "6",
"Length" => "41",
"Highway_mpg" => "21",
"@version" => "1",
"message" => "17,\"Manual,Transmission\",Four-wheel drive,Jeep 3.6L 6 Cylinder 280 hp 260 lb-ft,Gasoline,34,21,285,False,2012 Jeep Wrangler Arctic,41,Jeep,2012 Jeep Wrangler,6,260,6 Speed Manual,79,2012",
"Fuel_Type" => "Gasoline",
"Engine_Type" => "Jeep 3.6L 6 Cylinder 280 hp 260 lb-ft",
"path" => "/home/paulsteven/log_cars/cars.csv",
"Hybrid" => "False",
"ID" => "2012 Jeep Wrangler Arctic",
"@timestamp" => 2019-04-20T07:58:26.552Z,
"Transmission" => "6 Speed Manual"
}
这是配置文件:
input {
file {
path => "/home/paulsteven/log_cars/cars.csv"
start_position => "beginning"
sincedb_path => "/dev/null"
}
}
filter {
csv {
separator => ","
columns => ["City_mpg","Classification","Driveline","Engine_Type","Fuel_Type","Height","Highway_mpg","Horsepower","Hybrid","ID","Length","Make","Model_Year","Number_of_Forward_Gears","Torque","Transmission","Width","Year"]
}
kv {
recursive => "true"
}
}
output {
elasticsearch {
hosts => "localhost:9200"
index => "kvfilter1"
document_type => "details"
}
stdout{}
}
答案 0 :(得分:0)
找到了一些在kv过滤器中进行递归的示例:
input { generator { count => 1 message => 'foo=1,bar="foor=10,barr=11"' } }
filter {
kv { field_split => "," value_split => "=" recursive => false }
}
会产生
"foo" => "1",
"bar" => "foor=10,barr=11",
而
input { generator { count => 1 message => 'foo=1,bar="foor=10,barr=11"' } }
filter {
kv { field_split => "," value_split => "=" recursive => true }
}
会产生
"foo" => "1",
"bar" => {
"foor" => "10",
"barr" => "11"
},
