原文 The average amount of wait time (milliseconds) for each lock request that resulted in a wait. In SQL Server 2000, the Batch Requests/sec counter of the SQL Statistics performance object increases one time for each RPC. This behavior occurs even if RPC calls are batched together in a single batch. In the original release version of SQL Server 2005 and in SQL Server 2005 SP1, this behavior was changed so that the counter increases one time for each batch. Therefore, if multiple RPCs arrive in the same batch, the counter The performance measure buffer cache hit ratio expresses as a percentage, how often a request for a database data page, can be served from the Buffer Pool. The alternative action is for SQL Server to have to fetch the data page from disk.(Percentage of pages In SQL Server, Cache can be included Log Cache Buffer Cache as well as Procedure Cache, it is an overall ratio.(Ratio between cache hits and lookups) Number of pages flushed by checkpoint or other operations that require all dirty pages to be flushed. Number of unrestricted full scans per second. These can be either base-table or fullindex scans.(Number of unrestricted full scans. These can either be base table or full Indicates the number of buffers written per second by the buffer manager's lazy writer. Current number of processes waiting for a workspace memory grant Number of lock requests that resulted in a deadlock. Number of seconds a page will stay in the buffer pool without references. Number of page splits per second that occur as a result of overflowing index pages. The number of times per second that SQL Server compilations occurred. The number of times per second that SQL Server recompilations occurred. Number of pages used for miscellaneous server purposes (including procedure cache). The ideal number of pages in the buffer pool. Total amount of dynamic memory the server is willing to consume. Number of temporary tables/table variables created/sec The number of pages in the buffer pool (includes database, free, and stolen pages). Total amount of dynamic memory the server is currently consuming. Disk Time is the percentage of elapsed time that the selected disk drive is busy servicing read or write requests. % Idle Time reports the percentage of time during the sample interval that the disk was % Interrupt Time is the time the processor spends receiving and servicing hardware interrupts during sample intervals. This value is an indirect indicator of the activity of devices that generate interrupts, such as the system clock, the mouse, disk drivers, data communication lines, network interface cards and other peripheral devices. These devices normally interrupt the processor when they have completed a task or require attention. Normal thread execution is suspended during interrupts. Most system clocks interrupt the processor every 10 milliseconds, creating a background of interrupt % Privileged Time is the percentage of elapsed time that the process threads spent executing code in privileged mode. When a Windows system service in called, the service will often run in privileged mode to gain access to system-private data. Such data is protected from access by threads executing in user mode. Calls to the system can be explicit or implicit, such as page faults or interrupts. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes.
