Cosmos DB Profiler is a desktop diagnostic and monitoring tool designed to analyze, inspect and optimize workloads running on Azure Cosmos DB. It provides visibility into requests, queries, stored procedures and data operations executed against Cosmos DB accounts. The tool captures live traffic from applications and presents detailed insights into request charges, execution times, query behavior and indexing usage. It enables developers and database administrators to detect inefficiencies, identify high RU consumption and troubleshoot performance bottlenecks. Cosmos DB Profiler is intended for development, testing and production troubleshooting scenarios where understanding database behavior and cost drivers is critical. It operates as an external monitoring and profiling solution, connecting securely to Azure Cosmos DB instances to observe activity without modifying application code. The product focuses on operational transparency and performance diagnostics rather than database hosting or management. It is used to improve query design, indexing strategies and overall workload efficiency in Cosmos DB environments.
