Hi @Srinivas_Kondapally,

I see that you are using Logstash on a Windows OS. If you were to use the command-line flag '-e' with its value in double quotes, it should work. For example:

  • logstash -e "input{stdin{}}output{stdout{}}"

As mentioned in our documentation, you could achieve similar results by running the following command: logstash -e "" (empty string value). This would use the default input/output plugins (stdin and stdout respectively).
