Logstash and Filebeat in 5 minutes

What/Why?

• Filebeat is a log shipper, capture files and send to Logstash for processing and eventual indexing in Elasticsearch
• Logstash is a heavy swiss army knife when it comes to log capture/processing
• Centralized logging, necessarily for deployments with > 1 server
• Super-easy to get setup, a little trickier to configure
• Captured data is easy to visualize with Kibana
• Wny not just Logstash (ELK is so hot right now)?
