Elastic stack

Environment

To understand the Elastic Stack platform, let’s assume that Elasticsearch is a document database that stores the structured document.

The Log file format is unstructured data. Every single line of a log cannot be a single document. So, we need to parse the message and extract the key and values of the field. The program, Logstash read the files and made a structured document from an unstructured log file based on a single implemented log parser script.
