Logstash is a tool for receiving, processing and outputting logs. All kinds of logs.
System logs, webserver logs, error logs, application logs and just about anything
you can throw at it. Sounds great, eh?
Using Elasticsearch as a backend datastore, and kibana as a frontend reporting tool,
Logstash acts as the workhorse, creating a powerful pipeline for storing, querying and
analyzing your logs. With an arsenal of built-in inputs, filters, codecs and outputs, you
can harness some powerful functionality with a small amount of effort.
