Key Features
-
Optimized for Production: The agent has a smaller footprint, ensuring that only the essential plugins needed for production are included. By employing techniques like dead code elimination and interprocedural optimization, it guarantees efficient deployments.

Long-Term Support (LTS): With predictable and reliable 24-month support, users benefit from weekly security patches and critical updates, as well as a quarterly release schedule that emphasizes long-term stability.
-
Advanced Capabilities: The agent includes features such as performant log deduplication, capable of reducing costs by up to 40%. It supports high-volume environments with log sampling processing, AI-based filtering, and routing. Additionally, it provides native flattening for OpenSearch/Elasticsearch, ensuring type safety and automatic conflict resolution.
