Offers cost-effective log management with strong correlation features across observability tools
Grafana Loki's open-source capability is a significant benefit. Grafana has invested in making their enterprise tools competitive with other APM tools, facilitating cross-correlation with Mimir and Tempo for metrics and tracing. The tool offers good search functionality, and its on-premises capability is advantageous. The indexing performance is strong, making it a robust log management tool. Grafana Loki is notably cost-effective.

Exploring resilience and integration capabilities while navigating complexity and technical challenges
Logstash lacks a graphical user interface, necessitating a strong programming background to handle it effectively. It is challenging for business users who need a skilled team for its operation. Changing pipelines is not easy because Logstash requires pipelines to be programmed and cannot just be dragged and dropped like other data solutions. Additionally, Logstash does not automatically make actions based on the data it receives; integrating automation tools is required.
