+## Using Grafana Loki to evaluate pino logs in a kubernetes cluster
+
+To get pino logs into Grafana Loki there are two options:
+
+1. **Push:** Use [pino-loki](https://github.com/Julien-R44/pino-loki) to send logs directly to Loki.
+1. **Pull:** Configure Grafana Promtail to read and properly parse the logs before sending them to Loki.  
+   Similar to Google Cloud logging, this involves remapping the log levels. See this [article](https://medium.com/@janpaepke/structured-logging-in-the-grafana-monitoring-stack-8aff0a5af2f5) for details.
