# Serverless Monitoring for Azure Cosmos DB

## Overview{% #overview %}

Datadog APM uses **inferred spans** to collect traces and trace metrics from Azure Cosmos DB CRUD operations. These spans appear directly in flame graph and waterfall views. Cosmos DB distributed tracing requires no additional setup beyond existing instrumentation for APM users.
