![]() ![]() Session ID – It is a unique number assigned to every new process when it made a connection to SQL Server. ![]() The following data is displayed directly in the associated table: Processes – the section displays a list of all active processes that are connected and executing on the monitored SQL Server instance. The Activity monitor page is organized in the three main performance sections: Processes, Active expensive queries, and Resource waits. While the instance dashboard displays the 3 most essential Activity monitor performance charts, for detailed activity monitor data, open the dedicated Activity monitoring page via Details link in the Activity monitor section of the instance dashboard. The chart refresh rate is fixed and cannot be changed by the user. The charts read and display the data from the monitored instance every five seconds. For more information read SQL Server performance counters (Batch Requests/sec or Transactions/sec): what to monitor and why Batch Requests/sec – The metric reflects the SQL Server performance by displaying the number of SQL Server batches that the monitored SQL Server instance receives in one second.Database I/O – Displays the current transfer rate when database engine reads/writes data blocks from disk into memory, from memory to a disk or from disk to disk.Waiting tasks – the chart displays the number of SQL Server tasks that are currently waiting for various resources such as CPU, memory or I/O.In ApexSQL Monitor, the instance dashboard is the first stop where activity monitor data is presented in three charts: Waiting Tasks, Database I/O, Batch requests/sec. It combines real-time SQL Server performance data collected from various parts of SQL Server and presents it in a graphical and tabular form for easier and faster review and understanding. The ApexSQL Monitor activity monitor is a real-time monitoring feature that displays SQL Server processes related performance data to help to understand the impact of these processes on the monitored SQL Server instance. How is the activity monitor data classified?Ĭan I see those data for a specific database of interest? How can I access more detailed information about the current SQL Server activity? How frequently are the Activity monitor charts refreshing in the Instance dashboard? ![]()
