Error while ingest data

Elastic Stack Logstash
1

I am trying to ingest logs and getting error that - The signal HUP is in used by JVM and will not work currectly on this platform.
I am using this command :

logstash -e 'input { stdin { } } output { elasticsearch { host => localhost } stdout { } }'

Please help...

I am looking for good tutorial to ingest logs using Logstash to ElasticSearch.

I'm pretty sure that the only consequence of this message is that if you interrupt the Logstash process by hitting Ctrl+C its shutdown won't be as graceful as one would want.
