Grafana Loki Fundamentals and Architecture

Grafana Loki is a horizontally scalable, highly available log aggregation system. It is designed for simplicity and cost-efficiency. Created by Grafana Labs in 2018, Loki has rapidly emerged as a compelling alternative to traditional logging systems, particularly for cloud-native and Kubernetes environments. Loki can provide a comprehensive log journey. We can select the right log streams and then filter to focus on the relevant logs. We can then parse structured log data to be formatted for our customized analysis needs. Logs can also be transformed appropriately for presentation, for example, or further pipeline processing.
