This guide provides step-by-step instructions on setting up Grafana and Loki to effectively monitor Milvus deployments. Milvus is a distributed vector database designed for storing, indexing, and managing massive embedding vectors. Grafana is an open-source platform for monitoring and observability, while Loki pairs with Grafana as a log aggregation system. Together, they offer a solid monitoring setup for Milvus and beyond. The prerequisites include Docker, Kubernetes, Helm, and kubectl. After setting up the K8s cluster, users can deploy Grafana and Loki using Helm. Finally, configure Grafana data sources and dashboard to visualize and query logs effectively.
