Prometheus Metrics Querying And Analysis

via “observability with metrics, telemetry, and distributed tracing”

Weaviate is an open-source vector database that stores both objects and vectors, allowing for the combination of vector search with structured filtering with the fault tolerance and scalability of a cloud-native database​.

Unique: Implements comprehensive metrics across all layers (API, storage, cluster) with OpenTelemetry integration for distributed tracing. Metrics are configurable with sampling to reduce overhead.

vs others: More comprehensive than Pinecone's metrics because all layers are instrumented; better than Elasticsearch because tracing is built-in via OpenTelemetry.
