Question

Your team needs to investigate individual data-plane requests against an Azure Cosmos DB for NoSQL account — including the RU charge, status code, partition key range, and request duration for each operation over the past week. Metrics in Azure Monitor only show aggregated values and are insufficient for this per-request analysis. What must you configure to enable this level of investigation?

Accepted Answer

Create diagnostic settings on the Cosmos DB account to send the DataPlaneRequests log category to a Log Analytics workspace, then query it with KQL.

Answer

Enable the Azure Cosmos DB integrated cache on a dedicated gateway to capture per-request telemetry.

Answer

Increase the metrics retention period in Azure Monitor Metrics to 30 days and filter by the RequestCharge dimension.

Answer

Turn on continuous backup mode so that point-in-time request history is retained for auditing.
