Logstash is a data pipeline that helps us process logs and other event data from a variety of sources.

With over 200 plugins, Logstash can connect to a variety of sources and stream data at scale to a central analytics system. It’s also an important part of one of the best solutions for the management and analysis of logs and events: the ELK stack (Elasticsearch, Logstash, and Kibana).

The ability to efficiently analyze and query the data shipped to the ELK Stack depends on the readability and quality of data. This implies that if unstructured data (e.g., plain text logs) is being ingested into the system, it must be translated into structured form enriched with valuable fields. Regardless of the data source, pulling the logs and performing some magic to format, transform, and enrich them is necessary to ensure that they are parsed correctly before being shipped to Elasticsearch.
