Logstash

wikipedia:Logstash is a light-weight, open-source, server-side data processing pipeline that allows you to collect data from a variety of sources, transform it on the fly, and send it to your desired destination. It is most often used as a data pipeline for Elasticsearch, an open-source analytics and search engine. Logstash integrates with Elasticsearch and has over 200 pre-built open-source plugins that can help to index your data.
