Transact-SQL (T-SQL) query to return the status and detail information for all SQL Server Full-Text Catalogs on an SQL Server instance

We have about 200 user databases in which we have the full-text search enabled and these databases contain several tables. As part of my daily checks, I have to check the status of all full-text catalogs, to ensure that all full-text catalogs are successfully populated without errors. However, to check the status of every full-text catalog using SQL Server Management Studio is a challenge and very time consuming task.  So, to make my life easier, I wrote the following T-SQL script that quickly returns the status of all full-text catalogs and their population status.

SELECT DB_NAME(ftsac.[database_id]) AS [db_name]
	,DATABASEPROPERTYEX(DB_NAME(ftsac.[database_id]), 'IsFulltextEnabled') AS [is_ft_enabled]
	,ftsac.[name] AS [catalog_name]
	,mfs.[name] AS [ft_catalog_file_logical_name]
	,mfs.[physical_name] AS [ft_catalog_file_physical_name]
	,OBJECT_NAME(ftsip.[table_id]) AS [table_name]
	,FULLTEXTCATALOGPROPERTY(ftsac.[name], 'IndexSize') AS [ft_catalog_logical_index_size_in_mb]
	,FULLTEXTCATALOGPROPERTY(ftsac.[name], 'AccentSensitivity') AS [is_accent_sensitive]
	,FULLTEXTCATALOGPROPERTY(ftsac.[name], 'UniqueKeyCount') AS [unique_key_count]
	,ftsac.[row_count_in_thousands]
	,ftsip.[is_clustered_index_scan]
	,ftsip.[range_count]
	,FULLTEXTCATALOGPROPERTY(ftsac.[name], 'ImportStatus') AS [import_status]
	,ftsac.[status_description] AS [current_state_of_fts_catalog]
	,ftsac.[is_paused]
	,(
		SELECT CASE FULLTEXTCATALOGPROPERTY(ftsac.[name], 'PopulateStatus')
				WHEN 0
					THEN 'Idle'
				WHEN 1
					THEN 'Full Population In Progress'
				WHEN 2
					THEN 'Paused'
				WHEN 3
					THEN 'Throttled'
				WHEN 4
					THEN 'Recovering'
				WHEN 5
					THEN 'Shutdown'
				WHEN 6
					THEN 'Incremental Population In Progress'
				WHEN 7
					THEN 'Building Index'
				WHEN 8
					THEN 'Disk Full. Paused'
				WHEN 9
					THEN 'Change Tracking'
				END
		) AS [population_status]
	,ftsip.[population_type_description] AS [ft_catalog_population_type]
	,ftsip.[status_description] AS [status_of_population]
	,ftsip.[completion_type_description]
	,ftsip.[queued_population_type_description]
	,ftsip.[start_time]
	,DATEADD(ss, FULLTEXTCATALOGPROPERTY(ftsac.[name], 'PopulateCompletionAge'), '1/1/1990') AS [last_populated]
FROM [sys].[dm_fts_active_catalogs] ftsac
INNER JOIN [sys].[databases] dbs
	ON dbs.[database_id] = ftsac.[database_id]
LEFT JOIN [sys].[master_files] mfs
	ON mfs.[database_id] = dbs.[database_id]
		AND mfs.[physical_name] NOT LIKE '%.mdf'
		AND mfs.[physical_name] NOT LIKE '%.ndf'
		AND mfs.[physical_name] NOT LIKE '%.ldf'
CROSS JOIN [sys].[dm_fts_index_population] ftsip
WHERE ftsac.[database_id] = ftsip.[database_id]
	AND ftsac.[catalog_id] = ftsip.[catalog_id];

Here is the description of the columns of this script result set:

• db_name – Name of the SQL Server database, unique within an instance of SQL Server
• is_ft_enabled – The value of 1 indicates that the full-text and semantic indexing is enabled
• ft_catalog_file_logical_name – Returns the logical file name of the full-text index catalog file
• ft_catalog_file_physical_name – Returns the phyisical file name of the full-text index catalog file
• table_name – Returns the name of the table where full-text index exists
• ft_catalog_logical_index_size_in_mb – Returns the logical size of the full-text catalog in megabytes(MB)
• is_accent_sensitive – Returns the accent-sensitivity setting for full-text catalog. The value of 1 indicates that full-text catalog is accent sensitive
• unique_key_count – Returns the number of unique keys in the full-text catalog
• row_count_in_thousands – Returns the estimated number of rows (in thousands) in all full-text indexes in this full-text catalog
• is_clustered_index_scan – Indicates whether the population involves a scan on the clustered index
• range_count – Returns the number of sub-ranges into which this population has been parallelized
• import_status – Indicates whether the full-text catalog is being imported. The value of 1 indicates that the full-text catalog is being imported
• current_state_of_fts_catalog – Returns the state of the full-text catalog
• is_paused – Indicates whether the population of the active full-text catalog has been paused
• population_status – Returns the status of current population
• ft_catalog_population_type – Returns the type of full-text catalog population type
• status_of_population – Returns the status of this population
• completion_type_description – Returns the description of status of the population
• queued_population_type_description – Returns description of the population to follow, if any. For example, when CHANGE TRACKING = AUTO and the initial full population is in progress, this column would show “Auto population.”
• start_time – Returns the time that the population started.
• last_populated – Returns the time when the last full-text index population completed

I wrote this script using function FULLTEXTCATALOGPROPERTY and following system views and dmvs:

• sys.databases
• sys.master_files
• sys.dm_fts_active_catalogs
• sys.dm_fts_index_population.

Hope you will find this post useful ;) .
