Get a closer look with visualizations, metrics, and SLAs. Monitoring has always been a big part of solutions design. It is a continuous process of data collection about a system for the purpose of analyzing that system. Monitoring is usually done in an active way, with a tool pinging or probing a system in order to get responses. Those responses are then analyzed to better understand how the system is performing.

Extended Events provides data about the individual execution of queries, while Query Store and the DMVs aggregate performance data. In order to use Query Store and Extended Events, you have to configure them in advance – either enabling Query Store for your database(s), or setting up an XE session and starting it.
