Logstash
Logstash is Elastic's open-source data processing pipeline that ingests and transforms data from many sources and sends it to destinations such as Elasticsearch.
Logstash is a server-side data processing tool developed by Elastic. It receives logs and events, parses and enriches them with filters, and sends the results to stores such as Elasticsearch. Together with Elasticsearch and Kibana it forms the Elastic Stack, and the L in ELK stands for Logstash.
