Capturing Windows Performance Counters for SQL Server

SQL Server Performance Counters

The following counters are the recommended list to capture baseline performance metrics for SQL Server:

• Memory                                              Available Mbytes             (already added above)
• Memory                                              Page Faults/sec                (already added above)
• Memory                                              Page Reads/sec                                (already added above)
• Memory                                              Page Writes/sec               (already added above)
• Paging File                                           % Usage (_Total)              (already added above)
• Processor                                            % Privileged Time (_Total)
• Processor                                            % Processor Time (_Total)
• Processor                                            % User Time (_Total)
• Physical Disk                                       % Idle Time (_Total)
• Physical Disk                                       Avg. Disk Queue Length (_Total)
• Physical Disk                                       Avg. Disk sec/Read (_Total)
• Physical Disk                                       Avg. Disk sec/Transfer (_Total)
• Physical Disk                                       Avg. Disk sec/Write (_Total)
• SQL Server: Access                              Methods/Page Splits/sec
• SQL Server: Buffer Manager                  Buffer Cache Hit Ratio
• SQL Server: Buffer Manager                  Page Life Expectancy
• SQL Server: Buffer Manager                  Page Lookups/sec
• SQL Server: Buffer Manager                  Page Reads/sec
• SQL Server: Buffer Manager                  Page Writes/sec
• SQL Server: General Statistics               User Connections
• SQL Server: Memory Manager                Memory Grants Pending
• SQL Server: SQL Statistics                    Batch Requests/sec
• SQL Server: SQL Statistics                    SQL Compilations/sec

• SQL Server: Wait Statistics                   Network IO Waits <all instances>
• SQL Server: Wait Statistics                   Non-Page Latch Waits <all instances>
• SQL Server: Wait Statistics                   Page IO Latch Waits <all instances>
• SQL Server: Wait Statistics                   Page Latch Waits <all instances>
• System                                               Processor Queue Length

TypePerf

Microsoft provides a command line utility “TypePerf” which allows capturing counters from a remote system to a monitoring system and logging these either to the command window or a log file. 

More information about the TypePerf command can be found at:

https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/nt_command_typeperf.mspx?mfr=true

Using TypePerf with an Input File

Create a folder on the monitoring server named “TypePerf”.

Create a new file in the TypePerf folder named
TypePerf_SQLCounters.txt.

Edit the TypePerf_SQLCounters.txt file by copying the following
contents into the file:

\\SERVERNAME\Memory\Available Bytes

\\SERVERNAME\Memory\Page Reads/sec

\\SERVERNAME\Memory\Page Writes/sec

\\SERVERNAME\Paging File(_Total)\% Usage

\\SERVERNAME\PhysicalDisk(_Total)\% Disk Time

\\SERVERNAME\PhysicalDisk(_Total)\Avg. Disk Queue Length

\\SERVERNAME\PhysicalDisk(_Total)\Avg. Disk sec/Read

\\SERVERNAME\PhysicalDisk(_Total)\Avg. Disk sec/Transfer

\\SERVERNAME\PhysicalDisk(_Total)\Avg. Disk sec/Write

\\SERVERNAME\Processor(_Total)\% Privileged Time

\\SERVERNAME\Processor(_Total)\% Processor Time

\\SERVERNAME\Processor(_Total)\% User Time

\\SERVERNAME\SQLServer:Access Methods\Page Splits/sec

\\SERVERNAME\SQLServer:Buffer Manager\Buffer cache hit ratio

\\SERVERNAME\SQLServer:Buffer Manager\Page life expectancy

\\SERVERNAME\SQLServer:Buffer Manager\Page lookups/sec

\\SERVERNAME\SQLServer:General Statistics\User Connections

\\SERVERNAME\SQLServer:Memory Manager\Memory Grants Pending

\\SERVERNAME\SQLServer:SQL Statistics\Batch Requests/sec

\\SERVERNAME\SQLServer:SQL Statistics\SQL Compilations/sec

\\SERVERNAME\SQLServer:SQL Statistics\SQL Re-Compilations/sec

\\SERVERNAME\SQLServer:Wait Statistics(*)\Memory grant queue
waits

\\SERVERNAME\SQLServer:Wait Statistics(*)\Network IO waits

\\SERVERNAME\SQLServer:Wait Statistics(*)\Page IO latch waits

\\SERVERNAME\SQLServer:Wait Statistics(*)\Page latch waits

\\SERVERNAME\System\Processor Queue Length

Perform a global replace of the SERVERNAME to match the actual server
name for the SQL Server that is to be monitored.  Save the file and Close.

Go to the Start menu -> Command Prompt.

Change the directory to the location where the TypePerf directory was created.

At the command prompt, modify the next command to match the information for the SQL Server being monitored:

TYPEPERF -cf F:\TypePerf\TypePerf_SQLCounters.txt -f csv -o F:\TypePerf\MSLAB2191_yyyymmdd_hhmm.csv -s BRTC_MSLAB2191

-cf           Name of the file that contains the list of counters to capture

-f             format of the log file, defaults to csv

-o            Path\name of output file

-s            Name of server to collect the counters from if one does not exist in the counter file

EXAMPLE:

TYPEPERF -cf F:\TypePerf\TypePerf_SQLCounters.txt -f csv -o F:\TypePerf\MSLAB2191_20161020_2025.csv -s BRTC_MSLAB2191

Press Enter to start the counter collection…

The [\]   will run the command and capture the counters every second.

Verify the file you specified for the output was created and is growing:

When you have completed the SQL Server test, Press CTRL-C to stop the counter collection.

Close the Command Prompt window.
