Logstash is a free and open server-side data processing pipeline that ingests data from a multitude of sources, transforms it, and then sends it to your favorite "stash."

Inputs, filters & outputs

Logstash dynamically ingests, transforms, and ships your data regardless of format or complexity. Derive structure from unstructured data with grok, decipher geo coordinates from IP addresses, anonymize or exclude sensitive fields, and ease overall processing.

Ingest data of all shapes, sizes, and sources

Data is often scattered or siloed across many systems in many formats. Logstash supports a variety of inputs that pull in events from a multitude of common sources, all at the same time. Easily ingest from your logs, metrics, web applications, data stores, and various AWS services, all in continuous, streaming fashion.

Parse & transform your data on the fly:

As data travels from source to store, Logstash filters parse each event, identify named fields to build structure, and transform them to converge on a common format for more powerful analysis and business value.

Logstash dynamically transforms and prepares your data regardless of format or complexity:

• Derive structure from unstructured data with grok
• Decipher geo coordinates from IP addresses
• Anonymize PII data, exclude sensitive fields completely
• Ease overall processing, independent of the data source, format, or schema.

The possibilities are endless with our rich library of filters and versatile Elastic Common Schema.

Choose your stash, transport your data: 

While Elasticsearch is our go-to output that opens up a world of search and analytics possibilities, it’s not the only one available.

Logstash has a variety of outputs that let you route data where you want, giving you the flexibility to unlock a slew of downstream use cases.

Create and configure your pipeline, your way:

Logstash has a pluggable framework featuring over 200 plugins. Mix, match, and orchestrate different inputs, filters, and outputs to work in pipeline harmony.

Ingesting from a custom application? Don’t see a plugin you need? Logstash plugins are easy to build. We’ve got a fantastic API for plugin development and a plugin generator to help you start and share your creations.
