Datadog provides end-to-end visibility into the health and performance of SQL Server instances, along with other technologies running alongside them. To monitor SQL Server performance, you can set up Datadog's SQL Server integration to collect metrics, distributed request traces, and logs in a single platform. The process involves installing and configuring the Agent, which gathers data from your hosts and sends it to Datadog for aggregation, visualization, and alerting. You can visualize SQL Server performance metrics using two out-of-the-box dashboards: a screenboard that provides real-time overview of SQL Server instances and a timeboard that correlates SQL Server metrics with system metrics and events. The integration also allows you to use distributed tracing and application performance monitoring (APM) to visualize requests in detailed flame graphs and generate latency, error, and throughput statistics for your applications. Additionally, Datadog's log management features enable you to correlate traces with system metrics to determine which services in your stack are contributing to issues, then examine the logs from those services to get context. With this setup, you can easily navigate between service-level dashboards, graphs of system metrics, and logs from moments of interest to troubleshoot issues in your SQL Server-based applications.
