Logstash is a versatile tool for ingesting and transforming event data, allowing users to stream data into Elasticsearch and visualize it with Kibana, while also supporting over 70 different outputs, including Amazon S3 for long-term archival. The S3 output feature enables users to store events in an S3 bucket for future retrieval or batch processing, with the option to use conditional logic to selectively route data streams to S3. Users can dynamically configure S3 prefixes using field references or event values, which is particularly beneficial for multi-tenant deployments. Recent updates to the S3 plugin include a move to asynchronous uploading, support for the latest AWS-SDK version, and the ability to dynamically choose the S3 destination structure. Data is buffered locally before being uploaded to S3, and the upload process is controlled by configurable rotation strategies based on file size and creation time. These enhancements provide users with greater control over their data archiving processes, making Logstash a practical tool for managing event streams efficiently.
