Job Messages

This collection provides a list of the job messages that were displayed as a result of running a specific SQL Server job.

Collection Sampling Intervals

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

Collection Metrics

Text, if any, of a SQL Server error.

The name of the step.

The ID of the step in the job.

ID of any SQL Server error message, which is returned if the job failed.

SQL Message Severity

The severity of any SQL Server error.

Status of the job execution.

The run status can have one of the following values:

•

•

•

•

•

The date and time when the job or step started execution. For an In Progress history, this is the date and time when the history was written.

The time, in seconds, which has elapsed since the beginning of the execution of the job or step format.

Latches and Locks

This collection provides statistic details about latches and locks, such as wait time, requests and occurrences.

Collection Sampling Intervals


Frequency Mode	Collection Interval (In Seconds)
Real-time	20
Online	60
Offline	300

Collection Metrics


Display Name	Description
Average Latch Hit Wait Time	The wait time of latch requests that were satisfied.
Average Lock Duration	Average duration of blocked lock requests (100 * Lock Wait) /Blocked Lock Requests.
Average Lock Requests Wait Time
Average Lock Wait Time	The average wait time, in milliseconds, of lock requests that were satisfied.
Blocked Lock Requests	Number of lock requests that could not be satisfied immediately, causing the caller to block and wait before acquiring the lock.
Blocked Lock Requests Ratio	The percentage of lock requests that required the caller to wait before acquiring the lock. A high percentage (over 20 percent), along with high Lock Wait, indicate that the system is not handling locks well and concurrency mechanisms need to be tuned. Excessive blocking can be a major cause of poor application performance, as the user of an application often does not realize that they are waiting on a lock held by another user. From their point of view, it often seems like their application has stopped responding. (100 * Blocked Lock Requests) / Lock Requests
Latch Wait Count	Number of latch requests that could not be satisfied immediately, causing the caller to block and wait before acquiring the latch.
Lock Requests	Number of new locks and lock conversions requested from the lock manager.
Lock Timeouts	The number of lock timeouts. By default, SQL Server never times out locks. However, many applications issue a SET LOCK_TIMEOUT statement to cause SQL Server to time out their locks after the specified interval. This metric shows how often these timeouts are being exceeded.
Lock Timeouts Bigger Than Zero	The number of lock timeouts. By default, SQL Server never times out locks (they will wait forever). However, many applications issue a SET LOCK_TIMEOUT statement to cause SQL Server to timeout their locks after the specified interval. This metric shows how often these timeouts are being exceeded.
Lock Wait Time	Total wait time, in milliseconds, for all lock requests that resulted in a wait.
Number Of Deadlocks	The number of lock requests that resulted in a deadlock. A Deadlock occurs when multiple SQL Server sessions request conflicting locks in such a way that two locks are blocked by one another.
Number Of Super Latches	Number of latches that are currently SuperLatches. Super Latches (or Sub-Latches) are latches that are generally used when data is accessed frequently (latches that are in shared lock mode (SH)). A regular latch is often “Promoted” to a Super/Sub latch in order to reduce the latch acquired on each lookup. Thus, when data is accessed many times for carrying out a read-only operation, the “newly promoted” Super/Sub latch will handle all requests for this data. An example to a Super/Sub latch would be an index root page accessed frequently.
Super Latch Demotions	Number of SuperLatches that have been demoted to regular latches. A latch is demoted when SQL Server determines that no thread requests a data help by Super/Sub latch, or when SQL Server needs to write to that data resource and need to acquire exclusive access to that source.
Super Latch Promotions	Number of latches that have been promoted to SuperLatches. A regular latch is often “Promoted” to a Super/Sub latch in order to reduce the latch acquired on each lookup. Thus, when data is accessed many times for carrying out a read-only operation, the “newly promoted” Super/Sub latch will handle all requests for this data. An example to a Super/Sub latch would be an index root page accessed frequently.
Total Latch Wait Time	The total amount of time, in milliseconds, that latch requests spent waiting during the last second.

Lock Statistics

This collection provides detailed statistics for each lock.

Collection Sampling Intervals


Frequency Mode	Collection Interval (In Seconds)
Real-time	20
Online	60
Offline	300

Collection Metrics


Display Name	Description
Deadlocks	The total number of deadlocks for the lock type. A Deadlock occurs when multiple SQL Server sessions request conflicting locks in such a way that two locks are blocked by one another.
Lock Requests	The summary of all lock requests, both for new locks and lock conversions.
Lock Timeouts	The number of lock requests per second that timed out, including requests for NOWAIT locks.
Lock Type	The name of the lock type.
Total Wait Time (seconds)	The total lock wait time for the lock type.
Total Waits	The total number of wait events for the selected lock type.

Locks List

This collection provides a list of locks used within a SQL Server instance, grouped by the lock type, mode, and status.

Collection Sampling Intervals


Frequency Mode	Collection Interval (In Seconds)
Real-time	60

Collection Metrics

The server process ID of the current user process.

The time the session was created.

SQL Server Login name.

The database that is being used by the current process.

The index that is being used by the current process (if any).

The name of the currently locked object.

The number of locks that share the same object and type.

The type of the resource that is currently being locked (Database, Table, Page, Row, Extent and so on).

The kind of lock that is being applied to the resource (Shared, Exclusive, Update, IntentShared, IntenExclusive and so on).

The status of the lock can be one of the following:

•

WAIT = wait for another resource

•

CNVT = converted to another resource

•

GRANT = the lock has granted
