Session Trace

This collection traces over events that occurred in the currently monitored SQL Server instance.

System.

This collection is an on-demand collection, which has no pre-defined sampling intervals.

SPID

The session unique identifier (Session Process ID).

The unique number that SQL Server has assigned to identify the selected session.

Start Time

The time when the class event started.

End Time

The time when the class event ended.

Event Class

The type of class that was traced.

Duration

The duration, in milliseconds, of the event class.

Text Data

The SQL text that was captured as a result of the trace event.

Reads

The number of logical disk reads carried out by the server on behalf of the event.

Writes

The number of physical disk writes carried out by the server on behalf of the event.

CPU

The amount of CPU time (in milliseconds) used by the event.

Database ID

ID of the current database.

Object Name

System-assigned ID of the object.

Index ID

ID for the index on the object affected by the event.

SQL PI Instance Statistics

SQL PI Instance Statistics.

CPU Usage

CPU consumption of all the requests running on the monitored instance. Value can be larger than clock time if there is more than one CPU running.

CPU Usage Rate

Rate of CPU consumption of all the requests running on the monitored instance.

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

The total number of logical writes operations performed by all requests running on 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.

SQL Server Connections Summary

The total number of blocking sessions.

Connections Running DBCC

The total number of sessions running a DBCC command.

Foreground Sessions

The total number of foreground sessions.

Internal Connections

The number of internal connections of the SQL Server instance.

Machine Connections

The number of Client computers that currently have at least one SQL Server session.

Max Block Time

The maximum duration (in seconds) a current process was blocked.

Max Connections Allowed

The maximum number of user connections that SQL server allows.

Max Threads Allowed

The maximum number of threads that SQL server is configured to handle.

SQL Active Threads

The total number of the instance’s currently active threads.

SQL Executions

The total number of time that the selected statement executed during the specified time range.

System Connections

The number of SQL Server system sessions.

Total Connections

The total number of SQL Server sessions, including user and system sessions.

User Active Connections

The number of non-system sessions that are actively processing in SQL Server or that are waiting on locks.

User Connections

The number of SQL Server user (non-system) sessions, excluding SQL Server Agent sessions.

User Inactive Connections

The number of non-system sessions that are not actively processing in SQL Server.

Worker Threads Used Percent

The percentage of active threads out of the maximum number of threads that SQL server is configured to handle.

SQL Server Global Variables

This collection provides general SQL Server parameters, such as I/O, networking, and database operational time.

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.

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.

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.
