When to Use It
-
You want centralized application and platform logs.
-
You want a log backend that integrates cleanly with Grafana and OpenTelemetry.
-
You want label-based querying through LogQL instead of full-text indexing.
Key Integration Points
-
OpenTelemetry collectors or Promtail-style agents forward logs to Loki.
-
Grafana provides the primary query and visualization interface.
-
Object storage and retention policy are major cluster-specific decisions.
