Promtail

Definition

Promtail is an agent that is used to collect logs from various sources and send them to Loki, a log aggregation system. It is designed to work seamlessly with Kubernetes, but it can also be configured to collect logs from other environments. Promtail reads logs from files, such as those generated by Docker containers, and forwards them to Loki for centralized storage and querying.
