SQL Server - Database Details Page

 

When you click on a database within the selected SQL Server, the following performance metrics are displayed.

 

Parameters

Description

Database Disk Utilization
  • Total MB - Displays the total the total disk space of all available data files(in MB).

  • Used % - Displays the percentage of used disk space.

  • Used MB - Displays the total disk space used by all data files (in MB).

  • Free % - Displays the percentage of free/unused disk space.

  • Free MB - Displays the free/unused disk space (in MB).

  • Growth % - Displays the percentage at which all data files grow.

Data File Details

  • File Name - Name of the data file.

  • Total MB - Displays the total disk space of all available data files(in MB).

  • Used % - Displays the percentage of used disk space.

  • Used MB - Displays the total disk space used by all data files (in MB).

  • Free % - Displays the percentage of free/unused disk space.

  • Free MB - Displays the free/unused disk space (in MB).

  • Growth % - Displays the percentage at which all data files grow.

  • Growth Rate - Displays the rate at which the data files grow.

  • Maximum size - The maximum size (in MB) up to which the data file can grow.
Log File Details
  • File Name - Name of the log file

  • Total MB - Displays the total the total disk space of all available log files(in MB).

  • Used % - Displays the percentage of used disk space.

  • Used MB - Displays the total disk space used by all log files (in MB).

  • Free % - Displays the percentage of free/unused disk space.

  • Free MB - Displays the free/unused disk space (in MB).

  • Growth % - Displays the percentage at which all log files grow.

  • Growth Rate - Displays the rate at which the log files grow

  • Maximum size - The maximum size (in MB) up to which the log file can grow

  • Log Cache Hit Ratio - Displays the log cache hit ratio file size.

  • Number of VLFs – Displays the number of VLFs (Virtual Log Files) created. A transaction log is split internally into smaller chunks called virtual log files. A large number of VLFs can cause degradation in performance when transaction log backups occur or in any transaction log related activities.

VLF Details


Clicking on the Number of VLFs will pop up and show the details of about virtual log files within the physical transaction log.

  • FileID - Physical log file identifier from sysfiles


  • FileSize - Virtual log file size ( in bytes )


  • StartOffset - Beginning point of the virtual log file


  • FSeqNo - Virtual log file's sequence number


  • Status - Whether the virtual file contains the active part of the transaction log. 0 means that virtual file does not contain the active portion of the log and it is available for log use ; 2 means that VLF is active


  • Parity - Parity information for virtual log file


  • CreateLSN - Log sequence number that began the virtual log file. (click here for more info)

Database Details
  • Creation Date - Date in which the Database was created


  • Database Mode - The recovery model for the database which shows how transactions are logged.

Transaction Details
  • Transactions/Min - Number of transactions started for the database per minute


  • Replication Transactions/Min - Number of replication transactions per minute


  • Bulk Copy Rows/Min - Number of rows bulk copied


  • Bulk Copy Throughput/Min - Amount of KiloBytes bulk copied


  • Backup/Restore Throughput/Min - Read/write throughput for backup/restore of a database


  • Log Cache Reads/Min - Reads performed through the log manager cache


Log Flush Details
  • Log Flush/Min - Number of log flushes


  • Log Flush Waits/Min - Number of commits waiting on log flush


  • Log Flush Wait Time - Total wait time (milliseconds)

 

In addition, SQLDBManager Plus displays the more in-depth performance metrics such as System Tables, Table Relationship, User Tables etc of the selected database in a pop-up window.

  • Total Space Used in MB - Size of the table (MB).
Table Relationship

Displays the various foreign key relationship that exists in the table.

  • Parent Table – Table which contains the primary / parent column for the foreign key.

  • Parent Column – The primary column for which a foreign exists.

  • Foreign Table – Table name of foreign key column.

  • Foreign Column – The foreign key column name.
User Tables

Displays current information about all the user tables in the database.

  • System Table Name - Name of the User Table.

  • Total Rows - Total number of rows present in that table.

  • Total Space Used in MB - Size of the table (MB).
View Details

Displays current information about various views in the database.

  • View Name - Name of the View.

  • Schema Name - Schema Name to which this view is associated.

  • IsIndexed - Shows if there is an index for the view ( 1 = Index Present, 0 = No Index ).

  • IsIndexable - Shows whether an index can be created ( 1 = Index can be created, 0 = No Index can be created ).

  • Create Date - Date on which the view was created.

  • Modify Date - Date on which the view was last modified.
Index Details

Displays information about various index that is present in the database.

  • Table Name - Name of the Table.

  • Index Name - Name of Index present in the table.

  • Maximum Size Row - Maximum size for a row in that table (in bytes).

  • Max Noleafindex Row - Maximum size of a nonleaf index row (in bytes).

  • File Group Name - Name of the filegroup (Primary or User-defined).

  • Column Name - Name of the column for which index is present.

  • Type - Data type of the Column.

  • Clustered Index - Shows if the index is a Clustered Index or not (Yes or No). A clustered index determines the physical order of data in a table.
