Num Executions	The number of statements executed during the current interval.
Num Executions Rate	Rate of statements executed during the current interval.
Total Logical Reads	The total number of logical reads operations performed by all requests running on the instance.
Total Logical Reads Rate	The average number of logical reads operations per second performed by all requests running in the instance.

Total Writes Rate	The average number of logical writes operations per second performed by all requests running in the instance.
Total Physical Reads	The total number of physical reads operations performed by all requests running in the instance.
Total Physical Rate	The average number of physical reads operations per second performed by all requests running in the instance.
Row Count	The number of rows that have been returned to the client.
Tempdb I/O	Amount of time spent waiting for IO against Tempdb.
Tempdb GAM Wait	Amount of time spent waiting for a Global Allocation Map (GAM) page of Tempdb. GAM page tracks which extents have been allocated. The high amount of wait for an allocation page may indicate that the Tempdb is not configured according to best practice recommendations.
Tempdb SGAM Wait	Amount of time spent waiting for a Shared Global Allocation Map (SGAM) page of Tempdb. SGAM tracks which extents are being used as mixed (shared) extents. The high amount of wait for an allocation page may indicate that the Tempdb is not configured according to best practice recommendations.
Tempdb PFS Wait	Amount of time spent waiting for a Free Space (PFS) page of Tempdb. PFS tracks the allocation status of each page and approximately how much free space it has left. The high amount of wait for an allocation page may indicate that the Tempdb is not configured according to best practice recommendations.
Plan Recompilations	The number of times the plan of the statement was recompiled. For batch - this metric indicates the number of times at least one statement in the batch was recompiled.
Elapsed Time	Amount of time it took for the execution to end. This includes both active and idle time.
Degree of Parallelism	The maximum number of SQL Server threads assigned to the activity.
Granted Query Memory	The maximum amount of memory (KB) allocated to the execution of an activity.

Collection Metrics


Display Name	Description
CPU Busy	The total time the SQL Server instance has spent working since it was last started. The result is displayed in CPU time increments, or “ticks”, and is aggregated for all CPU units, so it may exceed the actual elapsed time. NOTE: To convert the value to microseconds, multiply it by @@TIMETICKS.
CPU Idle	The total time the SQL Server instance has been idle since it was last started. The result is displayed in CPU time increments, or “ticks”, and is aggregated for all CPU units, so it may exceed the actual elapsed time. NOTE: To convert the value to microseconds, multiply it by @@TIMETICKS.
I/O Errors	The number of I/O errors encountered by SQL Server during the specified time range.
Instance Packet Errors	The number of packet errors encountered by SQL Server during the specified time range.
Instance Packets In	The total number of network packets that were being sent to SQL Server from client applications during the specified time range.
Instance Packets Out	The total number of network packets that were being sent from SQL Server to Client applications during the specified time range.
Instance Packets Total	The rate at which network packets are being sent and received from SQL Server to client applications.
Instance Packet Errors	The rate at which SQL Server is encountering network packet errors.
Total Read Rate	Total number of physical reads carried out by SQL Server since the instance was last started.
Total Write Rate	Total number of physical writes carried out by SQL Server since the instance was last started.

SQL Server Host

Purpose

This collection provides general details about the SQL Server host, such as the networking environment and the host's I/O and CPU consumption.

Type

System.

Collection Metrics


Display Name	Description
CPU Name	The unique identifier of the CPU within all CPUs.
CPU Usage	Time spent by the various sessions that consume CPU cycles. This reading is taken directly from the operating system, rather than from SQL Server wait states.
Disk Utilization	The percentage of time the busiest disk spent serving system-wide I/O requests. This metric serves as a measure for the system I/O load. High values may indicate device bottleneck.
Free Virtual Memory	The current amount of virtual memory available in percent.
Individual CPU Usage	CPU utilization of a single processor.
Memory Max Percent	The maximum memory, in percent, which SQL Server can obtain from the host physical memory.
Network Bandwidth	The total network bandwidth used capacity of the specified network card in percent.
Network Interface	The name of the network interface.
Network Total Bandwidth	The total network bandwidth capacity of the specified network card.
Network Used Bandwidth	The total network bandwidth used capacity of the specified network card.
Physical Host	Physical name of the SQL Server instance host machine.
Physical Memory	The amount (in megabytes) of host physical memory.
Physical Memory Available	The amount (in megabytes) of physical memory available to applications.
Physical Memory Used	The amount (in megabytes) of physical memory used by applications.
Physical Memory Used Percent	The amount (by percentage) of physical memory used by applications.
Process CPU Utilization	Indicates the CPU use by a single process.
Run Queue Length	System average run queue. The CPU run queue is a holding area for threads and processes that require the CPU when the CPU is busy serving other processes. The run queue length is an indicator of whether the system has sufficient CPU resources for all the processes it executes. High values, along with high CPU utilization, indicate that the system requires faster or additional CPU units to handle the given load.
Total Virtual Memory	The current amount of total virtual memory.
Used Virtual Memory	The current amount (in megabytes) of used virtual memory.
