Key facts

Problem solved: Logstash was created to solve the problem of aggregating, processing, and centralizing log and event data from disparate sources (servers, applications, network devices) into a single, queryable store. Before Logstash, organizations often relied on custom scripts or less flexible log shippers, making it difficult to normalize, enrich, and analyze data efficiently.
