![]() ![]() Command – indicates the SQL command used by the process at the moment of monitoring.In other cases, the state can have one of the following values: Running, Suspended, or Background If the process is in the runnable or sleep state, the state will be marked as N/A. State – indicates the state of the process.Memory use (KB) – displays the amount of memory measured in kilobytes that are being used by the process during the execution.Total physical I/O (MB) – the amount of data in megabytes that the process uses for operations of reading from, and writing to a physical disk.Total CPU (ms) – a time in milliseconds that the process has spent on the CPU during the execution.In case the actual monitoring process is the head blocker for other processes, the field displays the value of 1 Blocker – in situations where the blocking chain exists, the session that is the head blocker for the blocking chain is displayed here.In case that blocking doesn’t exist, the N/A is displayed Blocked by – in case that another process blocks the monitored process, the Session ID of that blocking process displays here.Wait type – the current or the last wait type that the particular process is forced to waits for.When the process is not in the state of waiting for resources the wait time displays the 0 as a value Wait time (ms) – displays the time in milliseconds that the particular process is waiting for one or more resources.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?
