Logical Disks

This collection displays the logical disk activity for each logical disk.








Disk Queue Length

Disk Queue length tracks the average number of I/O requests, from all disks in the system, which are queued and waiting for a disk during a sampled interval. This figure may include I/O activity generated by processes other than SQL Server.

Values that exceed the threshold set in this metric indicate a bottleneck.

Disk Queue Length


A flag indicating a threshold for the number of I/O requests that were outstanding on the busiest disk in the system.

Disk Percentage Used

The percentage of used space on the specified partition.

Disk Partition

The logical disks to which the Disk Queue Length value refers.

Partition Free Pct

The percentage of free space on the specified partition.

Partition Free Space

The amount of free space (in megabytes) on the specified partition.

Partition Total Space

The total space (in megabytes) on a particular partition.

Long Running Session

The Long Running Session collection collects long-running query that runs more than specific time.


Realtime Collection






Session ID

Session identifier

Serial Number

Session serial number



Container ID

Container Name

Elapsed Time

Elapsed time in seconds since the session has become active.

Oracle User Name

Oracle user name

OS User

Operating system client user name


Operating system program name


Operating system machine name


Name of the currently executing module

CPU Time

Amount of CPU time (in 10s of milliseconds) used by a session from the time a user call starts until it ends.

SQL Text

SQL Text

Memory Manager

This collection monitors how SQL Server stores and manages its memory.








% Total Server Memory

The total percentage of dynamic memory that the server is currently consuming.

This value is calculated as follows:

100 * (Total Server Memory / Physical RAM)

Cache Memory

Total amount of dynamic memory (in megabytes) that the server is using for the dynamic SQL cache.

Connections Memory

Memory (in megabytes) allocated to keeping track of each connection's attributes.

Locks Memory

Memory (in megabytes) allocated to keeping track of locks.

Max SQL Server Memory

The maximum amount of dynamic memory that the instance is allowed to consume.

Memory Growth Pressure

Relative amount of additional memory (presented as a percentage) that SQL Server is willing to consume.

Values higher than 20 percent might indicate that the system is low on physical memory.

The memory growth pressure value is calculated as follows:

100 – ((100 * Total Server Memory)

Target Server Memory)

Optimizer Memory

Work area for the Optimizer in megabytes.

Sort Hash Memory

Memory in megabytes used for the Sort, Hash, and Index operations.

Target Server Memory

The maximum memory allocation size in megabytes SQL Server can reach at a current time (this value may change during SQL Server's work).

Values significantly higher than Total Server Memory might indicate that the system is low on physical memory.

Total Server Memory

The total amount of dynamic memory (in megabytes) that the server is currently consuming.


This collection retrieves general data, such as role, state and status, about each database involved in the mirroring process.

SQL Server.







Connection Timeout

Defines the number of seconds that the principal database can be in Disconnected state, before the mirroring session will actually run a failover scenario to the mirroring database.

Database Name

The name of the database.

End Log LSN

The actual LSN (Log Sequence Number) of the mirroring session, This value should be equal to the Failover LSN value.

Failover LSN

The LSN (Log Sequence Number) value that the mirroring database should have in order to enable a smooth failover.


The name of the instance whose role in the mirroring process is Mirror.

Mirroring Role

The role the database takes in the mirroring process; either principal or mirror.

Mirroring Status

Indicates the severity determined based on the database state: Normal, Warning or Critical.

Partner Name

The server network address defined for the Partner.


The name of the instance whose role in the mirroring process is Principal.

Redo Queue

The redo queue size. This size can be either lett Unlimited or defined in MB.

Replication LSN

The LSN (Log Sequence Number) used by the replication session (If such a session exists).

Role Sequence

A cumulative number that indicates the number of role switches that took place between the two partners involved in the mirroring process.

Safety Level

The safety level at which the mirroring session is configured to work (high availability /high performance).

Witness Name

The server network address defined for the Witness.

Witness State

The state of the Witness instance (valid only when the High Safety level is configured).
