Hello,

try this,

logstash -e 'input{stdin{}}output{stdout{}}'

It will work fine.

hi ,

tried as suggested getting the following error

Suggestion [3,General]: The command logstash was not found, but does exist in the current location. Windows PowerShell d  
oes not load commands from the current location by default. If you trust this command, instead type ".\logstash". See "g  
et-help about\_Command\_Precedence" for more details.

I faced the same issue , hence tried the command as directed which is causing the error which is sent in the first message.
