Using JSON with LogStash

Question

I\'m going out of my mind here. I have an app that writes logs to a file. Each log entry is a JSON object. An example of my .json file looks like the following:

Answer 1

Try removing the json codec and adding a json filter

input {
  file {
    type => "json"
    path => "/logs/mylogs.log"
  }
}
filter{
    json{
        source => "message"
    }
}
output {
  file {
    path => "/logs/out.log"
  }
}

you do not need the json codec because you do not want decode the source JSON but you want filter the input to get the JSON data in the @message field only.

Hope this helps.
