Database Index Fragmentation Info

This collection provides information about index fragmentation in the currently monitored database.

SQL Server.

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

Database

The database ID.

Index

The index ID.

Index Property

The property name of each element of the index.

Owner

The schema owner.

Property Value

The value of each element of the index.

Table

The table ID.

Database Index Histogram

This collection provides the distribution of the range key and values within a specific database index.

SQL Server.

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

Avg Range Rows

Average number of rows that corresponds to the last high range and the current one inclusive (Range Rows / Distinct Range Rows for Distinct Range Rows > 0).

Distinct Range Rows

Number of distinct rows that correspond to the last high range and the current one inclusive.

Equal Rows

Number of rows that correspond to the current high range.

Range High Key

The upper bound value of a histogram step.

Range Rows

Number of rows that corresponds to the last high range and the current one inclusive.

Database Index List

This collection provides the distribution of the range key and values within a specific database index.

SQL Server.

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

DB Name

The name of the specified database.

FG Name

The name of the File Group where the index resides.

Free MB

The free size left for the index to grow, in megabytes.

Index Id

Unique identifier of the index.

Index MB

The size of the index at the time of its last statistics update, measured in megabytes.

Index Name

The name of the index.

Num Keys

The number of keys held by the index.

Orig Fill Factor

Represents the size the index occupies as a percentage of the total index page (8 KB).

Owner Name

The owner of the index.

Qualified Name

The full qualified name of the database object.

Row Mod Ctr

The number of row modifications made since statistics were last updated for this index.

Rows

The number of rows in the table.

Table Name

The table with which the index is associated.

Type

The index type.

Used MB

The actual size occupied by the index, in megabytes.

% Log Used

The percentage of used space within the file space allocated to the transaction log of each currently used database.

Log space can be freed up by backing up the log, or truncating it, using the truncate option (backup log <dbname> with truncate_only).

All log records that exist after the oldest open transaction cannot be freed.

Average Active Transactions

Average number of active transactions during the specified time range.

Average Log Flush Wait Time

Average amount of time (in milliseconds) spent waiting for log flushes in each database.

A high log flush wait time can result from a slow or overworked disk subsystem.

If a database has a consistently high value of log flush wait time, with no changes, run the SQL command CHECKPOINT on that database to force another log flush and check the value again.

Average Transactions

Average transactions for each database.

Average Transactions Rate

The average rate per second of transactions executed for each database.

Backup Throughput MB

Data transition size (in MB) of backup or restore commands that are reading or writing to the database. While backups are essential, other users will probably experience performance degradation while these operations run.

Backup Throughput Rate

The rate (measured in megabytes per second) at which backup or restore commands are reading or writing to the database. While backups are essential, other users may experience performance degradation while these operations run.

Bulk Copy Throughput

Data transition size (in MB) of data being loaded into the database using BCP (Bulk Copy Program) or BULK INSERT.

While BCP and BULK INSERT are the fastest way of getting data into SQL Server, other users will in most probability experience performance degradation while these operations run.

Bulk Copy Throughput Rate

The rate (measured in megabytes per second) at which data is being loaded into the database using BCP (Bulk Copy Program) or BULK INSERT.

Despite the top speed at which BCP and BULK INSERT can import data into SQL Server, system I/O performance may degrade while BCP operations are underway.

Database ID

The database ID.

Database Name

The name of the database.

DBCC Scans

The size (in MB) of data transition resulting from data logical read scans carried out by Database Console Commands (DBCC).

Log Cache

The total number of reads that were satisfied from the log cache, thereby avoiding physical log I/O operations.

Log Cache Hit Rate

The rate per second of log cache reads, namely: reads that were satisfied from the log cache, thereby avoiding physical log I/O operations.

Log Cache Hit Ratio

The percentage of reads that were satisfied from the log, thereby avoiding physical log I/O operations.

Log File Size

The amount of disk space that the log files are using.

Log Flush Wait Time

The amount of time spent waiting for log flushes in each database.

The log flush operation, which is necessary to guarantee that transactions can be recovered in the event of a system failure, is most commonly caused when a user is issuing a commit transaction.

A high log flush wait time can result from a slow or overworked disk subsystem. If a database has a consistently high value of log flush wait time, run the SQL command CHECKPOINT on that database to force another log flush, and then recheck the value.

Log Flushes

The total number of log pages that were being written to disk by the log writer process during the specified time range.

Log Flushes Rate Total

Number of times per second that the log caches of all of the instance’s databases are being flushed to disk.

Log Growth Count

The number of times the log has been expanded for each database.

Log Growth Count Rate

The number of times per second the log has been expanded for each database.

Log Reads

Log cache lookups.

Log Shrink Count

The number of times the log has been reduced for each database.

Log Truncation Count

The total number of log truncations performed for each database during the specified time range.

Log truncations can be carried out using either of the following methods:

The database has the trunc.log on chkpt. option turned on

Total Data Size

The amount of disk space that the data files are using.
