What Is Logstash?
Logstash is an open-source tool designed to handle large volumes of data by ingesting logs and event data from multiple sources, parsing and enriching that data, and then forwarding it to a destination like Elasticsearch or a database. Think of it as a smart filter and organizer that helps businesses collect raw data, clean it up, and make it ready for further analysis or visualization. It’s widely used in monitoring, security, and operational analytics workflows.
