如何在Logstash配置文件中包含过滤器?

您可以利用 json

input {
   file {
       path => "/Users/mysystem/Desktop/abc.log"
       start_position => beginning
       ignore_older => 0
   }
}
filter {
   json {
     source => "message"
   }
}
output {
  # this condition will be true if the log line is not valid JSON
  if "_jsonparsefailure" in [tags] {
    file {
       path => "/Users/mysystem/Desktop/nonjson.log"
    }
  }
  # this condition will be true if the log line is valid JSON
  else {
    file {
       path => "/Users/mysystem/Desktop/jsonformat.log"
    }
  }
}
