  • Automatic service discovery and log ingestion
  • Native integration with Grafana Loki
  • Support for multiple log formats and pipelines
  • Efficient log processing and forwarding
Use Cases:

Alternatives:
  • fluent-bit – Lightweight log processor and forwarder with wider output support
  • filebeat – Part of the Elastic Stack, designed for forwarding to Elasticsearch
