Logstash CSV is not working

csv, logstash

Solution

In the output you need to specify the codec.

For example, with your configuraiton,

input {
   file {
       path => [ "/root/logstash/temp.csv" ]
       start_position => "beginning"
   }
}
filter {
    csv {
        columns => ['A','B','C','D','E']
    }
}

output {
    stdout { 
        codec => rubydebug
    }
}

Add the codec and then you can get what you want.

{
   "message" => [
    [0] "p,q,r,s,t"
],
  "@version" => "1",
"@timestamp" => "2014-04-24T02:57:37.099Z",
         "A" => "p",
         "B" => "q",
         "C" => "r",
         "D" => "s",
         "E" => "t"
}

Problem

I am trying to read CSV data in logstash, but some how logstash isn't able to split strings considering them as csv logstash config ``` input { file { path => [ "/root/logstash/temp.csv" ] start_position => "beginning" } } filter { csv { columns => ['A','B','C','D','E'] } } output { stdout { } } ``` Test CSV file ``` p,q,r,s,t p,q,r,s,t p,q,r,s,t p,q,r,s,t p,q,r,s,t p,q,r,s,t ``` Output of logstash ``` 2014-04-23T13:26:53.415+0000 0.0.0.0 p,q,r,s,t 2014-04-23T13:26:53.416+0000 0.0.0.0 p,q,r,s,t 2014-04-23T13:26:53.416+0000 0.0.0.0 p,q,r,s,t 2014-04-23T13:26:53.417+0000 0.0.0.0 p,q,r,s,t 2014-04-23T13:26:53.417+0000 0.0.0.0 p,q,r,s,t 2014-04-23T13:26:53.418+0000 0.0.0.0 p,q,r,s,t ``` Can somebody help me with this issue? 1) I have tried replacing single quote with double quotes in Columns 2) I tried with different data I am expecting columnar output as mentioned in this link https://blog.trifork.com/2014/01/28/using-logstash-elasticsearch-and-kibana-to-monitor-your-video-card-a-tutorial/
