# Logstash [introduction]
|
||
|
||
Logstash is an open source data collection engine with real-time pipelining capabilities.
|
||
Logstash can dynamically unify data from disparate sources and normalize the data into destinations of your choice.
|
||
Cleanse and democratize all your data for diverse advanced downstream analytics and visualization use cases.
|
||
|
||
While Logstash originally drove innovation in log collection, its capabilities extend well beyond that use case.
|
||
Any type of event can be enriched and transformed with a broad array of input, filter, and output plugins, with many native codecs further simplifying the ingestion process.
|
||
Logstash accelerates your insights by harnessing a greater volume and variety of data.
|
||
|
||
::::{admonition} {{ls}} to {{serverless-full}}
|
||
You’ll use the {{ls}} [{{es}} output plugin](logstash-docs-md://lsr/plugins-outputs-elasticsearch.md) to send data to {{serverless-full}}.
|
||
Note these differences between {{es-serverless}} and both {{ess}} and self-managed {{es}}:
|
||
|
||
* Use **API keys** to access {{serverless-full}} from {{ls}}. Any user-based security settings in your [{{es}} output plugin](logstash-docs-md://lsr/plugins-outputs-elasticsearch.md) configuration are ignored and may cause errors.
|
||
* {{serverless-full}} uses **data streams** and [{{dlm}} ({{dlm-init}})](docs-content://manage-data/lifecycle/data-stream.md) instead of {{ilm}} ({{ilm-init}}). Any {{ilm-init}} settings in your [{{es}} output plugin](logstash-docs-md://lsr/plugins-outputs-elasticsearch.md) configuration are ignored and may cause errors.
|
||
* **{{ls}} monitoring** is available through the [{{ls}} Integration](https://github.com/elastic/integrations/blob/main/packages/logstash/_dev/build/docs/README.md) in [Elastic Observability](docs-content://solutions/observability.md) on {{serverless-full}}.
|
||
|
||
**Known issue for Logstash to Elasticsearch Serverless.**
|
||
The logstash-output-elasticsearch `hosts` setting defaults to port :9200.
|
||
Set the value to port :443 instead.
