Hello, I'm working to install a brand new ELK stack. Following the installation of Logstash on 2012R2, I attempted to test it with the following command: logstash -e 'input { stdin { } } output { stdout {} }' I received the following error: Unrecognized option: Files\Elasticsearch\Logstash/heapdump.hprof" JVM creation failed I have no idea where to go from here. Any help would be greatly appreciated. ---

Perhaps something doesn't like that you've installed Logstash in a directory whose full path contains a space? ---
