Returns a miscellaneous set of useful information about the computer, and about the resources available to and consumed by SQL Server.
Current CPU tick count. CPU ticks are obtained from the processor's RDTSC counter. It is a monotonically increasing number.
Number of milliseconds since the computer was started.
Number of logical CPUs on the system.
Ratio of the number of logical or physical cores that are exposed by one physical processor package.
Amount of physical memory available.
Amount of virtual memory available to the process in user mode. This can be used to determine whether SQL Server was started by using a 3-GB switch.
Number of 8-KB buffers in the buffer pool. This amount represents committed physical memory in the buffer pool. Does not include reserved memory in the buffer pool.
Number of 8-KB buffers needed by the buffer pool. The target amount is calculated using a variety of inputs such as the current state of the system, including its load, the memory requested by current processes, the amount of memory installed on the computer, and configuration parameters. If the bpool_commit_target is larger than the bpool_committed value, the buffer pool will try to obtain additional memory. If the bpool_commit_target is smaller than the bpool_committed value, the buffer pool will shrink.
Number of 8-KB buffers in the buffer pool that are directly accessible in the process virtual address space. When not using the Address Windowing Extensions (AWE), when the buffer pool has obtained its memory target (bpool_committed = bpool_commit_target), the value of bpool_visible equals the value of bpool_committed.
When using AWE on a 32-bit version of SQL Server, bpool_visible represents the size of the AWE mapping window used to access physical memory allocated by the buffer pool. The size of this mapping window is bound by the process address space and, therefore, the visible amount will be smaller than the committed amount, and can be further reduced by internal components consuming memory for purposes other than database pages. If the value of bpool_visible is too low, you might receive out of memory errors.
Size of the call stack for each thread created by SQL Server.
Quantum for a non-preemptive task, measured in milliseconds. Quantum (in seconds) = os_quantum / CPU clock speed.
Error mode for the SQL Server process.
Priority class for the SQL Server process.
Maximum number of workers that can be created.
Number of user schedulers configured in the SQL Server process.
Total number of schedulers in SQL Server.
ID of the current deadlock monitor sequence.
ms_tick number when SQL Server last started. Compare to the current ms_ticks column.
Date and time SQL Server last started.
