Elastic Stack , the new kid in the block To put it in a nutshell, Elastic Stack is a set of applications capable of gathering log messages from several data sources and transforming them into a meaningful format so that it can be indexed and searched, and finally displaying interactive reports in order to visually analyze data, summarize information, etc.

It supports a wide variety of inputs that pull in events from common sources all at the same time. It filters, parses, and transforms data in order to derive structure from unstructured data regardless of format or complexity.

It outputs the data to Elastic Search, alerting and monitoring systems, and many other targets. It can scale from one single node up to hundreds of nodes in a transparent way. It also provides the clients with several languages like. Net, Java, and Python. Kibana Allows you to visualize the ElasticSearch data.
