Compared to other log aggregation systems, Loki: does not do full text indexing on logs. By storing compressed, unstructured logs and only indexing metadata, Loki is simpler to operate and cheaper to run. indexes and groups log streams using the same labels you’re already using with Prometheus, enabling you to…

About logging-operator
Logging operator The Logging operator is now a CNCF Sandbox project. The Logging operator solves your logging related problems in Kubernetes environments by automating the deployment and configuration of a Kubernetes logging pipeline. 1.

Fluent Bit queries the Kubernetes API and enriches the logs with metadata about the pods, and transfers both the logs and the metadata to a log forwarder instance. 1. The log forwarder instance receives…
