Loki is a log aggregation system designed for storing and querying logs at scale, inspired by Prometheus's approach but optimized for log data instead of metrics. Developers use Loki to centralize logs from their applications and infrastructure, then search and analyze them through a simple label-based query language. It integrates with Grafana for visualization and works well in cloud-native environments like Kubernetes.
