Top SQL Short Text

This collection retrieves part of a SQL text script of a given list of SQL handles.

SQL Server.

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

Collection Metrics

Object Name

The name of the object owning the SQL; for example, view, procedure or function. This value can be Unavailable for SQL statements that are not object-owned, such as Ad-Hoc queries.

Query Text

The SQL execution text. The text’s length is configurable, and its default value is 1000 characters.

Is Full Text

Indicates if all the retrieved text can be displayed in the short text field. This metric has a true value only for SQL statements whose text is shorter than the limit defined for short texts.

Top SQL Summary

This collection Summarizes data from the Top SQL collection.

SQL Server.

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

Collection Metrics

CPU Usage

Time spent by the various sessions consuming CPU cycles. This reading is taken directly from the operating system, rather than SQL Server wait states.

CPU Usage Rate

The average time (seconds) spent by the various sessions consuming CPU cycles.

Executions

Indicates the number of times the SQL script per SQL Handle executed

Total CPU

The total CPU time consumed by the SQL executions

Total Physical Reads

The total number of physical reads carried out for executing the SQL statements

Total Logical Reads

The total number of logical reads carried out for executing the SQL statements

Total Elapsed Time

The total time consumed for carrying out the SQL statement executions

Total CLR Time

The total CLR time spent for executing the SQL statements

Total I/O

The total number of I/O operations that were carried out for executing the SQL statements

Total Wait Time

The total wait time spent while executing the SQL statements

SQL Hit Rate

The percentage of SQL Statements that found the required plan already in the cache.

If a matching plan is found, SQL Server does not need to compile the query or the stored procedure. This can save a significant amount of CPU resources, and speed up SQL Server queries.

Traced SQL PA

This collection retrieves information about the most recent statements executed by the selected session, including statements that have also already completed running. Each statement refers to a specific execution.

SQL Server.

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

Active Time

Sum of all active wait events; equal to the session total activity within the specified time range.

CLR Wait

Time spent by the various sessions waiting for CLR code execution to complete.

CPU Usage

Time spent by the various sessions consuming CPU cycles.

This reading is taken directly from the operating system, rather than SQL Server wait states.

CPU Wait

Time spent by the various sessions waiting in the systems run queue for CPU cycles.

This reading is calculated from the operating system readings, rather than SQL Server wait states.

Database

The name of the database where the session is running.

Degree of Parallelism

Average number of SQL Server threads assigned to serve the current SQL statement.

End Time

The time when the selected statement’s execution ended.

Event (list)

The list of wait events for the selected SQL statement.

Event Wait (list)

Time spent on the wait events for the selected SQL statement.

Instance CPU Usage

The amount of CPU time that the SQL Server instance consumed.

IO Wait

Time spent by the various processes waiting for the completion of physical I/O operations.

Latch Wait

Time spent waiting for internal locks (latches) to be released.

Lock Wait

Time spent by the various sessions waiting for a blocking lock (held by another session) to be released.

Log Wait

Time spent waiting by the various processes waiting for a Log operation to complete.

Memory Wait

Time spent by the various sessions waiting for memory resources to be made available.

Network Wait

Time spent by the various sessions waiting for network I/O operations to complete.

Other Wait

Miscellaneous instance waits consisting of infrequent or otherwise special purpose wait states that should, in most cases, be very close to 0.

Physical IO

The total amount of I/O operations carried out so far by the statement.

Remote Provider Wait

The time spent by the various processes waiting for a remote OLEDB call to complete or DTS synchronization.

SPID

The process ID of the blocking session.

SQL Text

The short text of the SQL statement.

Start Time

The time when the SQL statement started.

Usability

This collection retrieves instance usability based on response time and instance availability.

SQL Server.

Real-time

60

Online

60

Offline

300

Availability

Indicates whether the SQL Server instance is available.

Instance Response Time

The full round-trip response time (in milliseconds) of a query representative of general workload (select 1, by default).

Instance Up Since

The SQL Server startup time.

Instance Up Time

The amount of time that the SQL Server instance was running during the current interval.

If the instance is down, no data collection occurs. Therefore, if this metric value is less than the interval length, the value of this metric reflects only the active portion of the interval.

Instance Unavailable

The relative amount of time that the SQL Server instance was down during the current interval. If the instance is down, no data collection occurs.

Connection Time

The time when the connection was established.

OS Connect Availability

Indicates whether a connection is available.
