- Ingests data from a multitude of inputs like files, databases, APIs, Kafka, S3 etc.
- Transforms and structures data through filtering, decoding, geolocation etc.
- Aggregates and stores important data for future retrieval and analysis.
- Flexible pipeline configuration through a multitude of input, filter, and output plugins.
- Ships processed data to various outputs e.g, Elasticsearch, external databases etc.
- Idempotent support to prevent data loss and ensure stability.
- Easy to scale horizontally to manage growth in data.
In summary, Logstash is a popular open source choice for ingesting data from multiple sources, processing it, transforming it, enriching it, and shipping it to various destinations for further analysis and visualization.
