14 File Stats Column Name Data Type database_id smallint ID of database. file_id smallint ID of file. sys.dm_io_virtual_file_stats Description sample_ms int Number of milliseconds since the instance of SQL Server has started. This column is can be used to compare different outputs from this function. num_of_reads bigint Number of reads issued on the file. num_of_bytes_read bigint Total number of bytes read on this file. io_stall_read_ms bigint num_of_writes bigint Number of writes made on this file. Total time, in milliseconds, that the users waited for reads issued on the file. num_of_bytes_written bigint Total number of bytes written to the file. io_stall_write_ms io_stall bigint bigint Total time, in milliseconds, that users waited for writes to be completed on the file. Total time, in milliseconds, that users waited for I/O to be completed on the file. size_on_disk_bytes bigint Number of bytes used on the disk for this file. For sparse files, this number is the actual number of bytes on the disk that are used for database snapshots. file_handle varbinary Windows file handle for this file.

16 T0 = Resource requested is unavailable Wait state begins T1 = Signal that resource is now available T2 = Start using resource Wait ends Signal Wait Time Time Wait Time sys.dm_os_wait_stats Column Name Data Type Description wait_type nvarchar(60) Name of the wait type. waiting_tasks_count wait_time_ms Bigint Bigint Number of waits on this wait type. This counter is incremented at the start of each wait. Total wait time for this wait type in milliseconds. This time is inclusive of signal_wait_time. T2 T0 max_wait_time_ms Bigint Maximum wait time on this wait type. signal_wait_time Bigint Difference between the time the waiting thread was signaled and when it started running. T2 T1

18 Operating System Object Counter Value Notes Processor % Processor Time <= 80% The higher it is, the more likely users are delayed. Processor % Privilege Time <30% of % Processor Time Amount of time spent executing kernel commands like SQL Server IO requests. Process(sqlservr) Process(msmdsrv) % Processor Time < 80% Percentage of elapsed time spent on SQL Server and Analysis Server process threads. System Processor Queue Length < 4 < 12 per CPU is good/fair, < 8 is better, < 4 is best
19 Some Disk IO and Memory Values Object Counter Value Notes Physical Disk Physical Disk Avg Disk Reads/sec Avg Disk Writes/sec * 10k~ k~ 150 It should be less than 85% of the disk capacity. Raid 0 = (r + w) / # of disks Raid 1 = [r + (2 * w)] / 2 Raid 5 = [r + (4 * w)] / # of disks Raid 10 = [r + (2 * w)] / # of disks r = reads, w = writes Physical Disk Avg. Disk Queue Length <2 The number of waiting I/O requests should be sustained at no more than 1.5 to 2 times the number of spindles that make up the physical disk. Physical Disk % Disk Time <90% Monitors the percentage of time that the disk is busy with read/write activity SQL Server:Buffer Manager Page reads/sec Page Writes/sec * Number of physical database page reads /write that are issued per second.
20 Sampling of SQL Server Counters Object Counter Value Notes Paging $Usage <70% Amount of page file currently in use Memory Available Mbytes >100 Amount of physical memory available to run processes on the machine SQL Server: Memory Manager Memory Grants Pending ~0 Current number of processes waiting for a workspace memory grant. SQL Server: Memory Manager Page Life Expectancy >=300 Time, in seconds, that a page stays in the memory pool without being referenced before it is flushed SQL Server: Buffer Manager Free List Stalls/sec < 2 Frequency that requests for db buffer pages are suspended because there are no buffers. SQL Server: Buffer Manager Buffer Cache Hit Ratio >90% Percentage of pages found in the buffer cache without having to read from disk.
21 Sampling of SQL Server Counters Object Counter Value Notes :Access Methods Forwarded Records/sec <10* :Access Methods Page Splits/sec <20* :Databases Log Growths/sec; Percent Log used < 1 and <80%, resp Tables with records traversed by a pointer. Should be < 10 per 100 batch requests/sec. Number of 8k pages that filled and split into two new pages. Should be <20 per 100 batch requests/sec. Don t let transaction log growth happen randomly! :SQL Statistics Batch Requests/sec * No firm number without benchmarking, but > 1000 is a very busy system. :SQL Statistics Compilations/sec ;Recompilations/ sec * Compilations should be <10% of batch requests/sec; Recompilations should be <10% of compilations/sec :Locks Deadlocks/sec < 1 # of lock requests that caused a deadlock.
