What is Logstash

Logstash is an open source product which picks data from multiple sources simultaneously and is used for server-side processing. Logstash transforms data which it picks and then sends to your stash like Elasticsearch.

In common words we can say that it is a log shipping agent that helps in transferring the logs to elasticsearch.
