I need to use logstash to read some log information from my own system. I'm using Elasticsearch as a output of the logstash. Elastic search will be configured in another server.

I read some articles and discussion forums, they are faced some memory consumption problem while using logstash.

How can I configure the logstash in my machine without affecting performance?

**My System configuration:**  
Windows server 2012  
8GB RAM  
500GB HDD

That's not a general problem with Logstash. I don't think this is something you should worry about.
