Monitoring and Diagnostics in Azure Cosmos DB for NoSQL

Running a database in production requires constant visibility into its health, speed, and reliability. When queries slow down or requests fail, understanding how to read and interpret the signals from your database is essential for keeping your applications online. This text-based course guides you through the process of monitoring, troubleshooting, and optimizing your Azure Cosmos DB for NoSQL databases. You will learn to decode REST response codes, analyze system events, and set up modern observability pipelines to catch issues before they impact your users. What you'll learn: - Understand foundational NoSQL monitoring concepts and core database terminology. - Analyze REST response codes to troubleshoot failed requests and rate-limiting issues. - Configure diagnostic logging and telemetry to track query performance and resource consumption. - Monitor database events and change feed activities to understand data mutations. - Apply structured troubleshooting workflows using built-in metrics and telemetry tools. You will start with the essential concepts of cloud database telemetry before moving into practical reading exercises that show you how to parse status codes, track latency, and set up automated alerts. This course is designed for beginner cloud developers, database administrators, and system engineers looking to build a solid foundation in database monitoring. No prior telemetry experience is required. Start reading today to gain complete visibility into your cloud database performance.
