sys.dm_fts_active_catalogs (Transact-SQL)
Returns information on the full-text catalogs that have some population activity in progress on the server.
Note
The following columns will be removed in a future version of Microsoft SQL Server: is_paused, previous_status, previous_status_description, row_count_in_thousands, status, status_description, and worker_count. Avoid using these columns in new development work, and plan to modify applications that currently use any of them.

Examples
The following example returns information about the active full-text catalogs on the current database.
SELECT catalog.name, catalog.is_importing, catalog.auto_population_count, OBJECT_NAME(population.table_id) AS table_name, population.population_type_description, population.is_clustered_index_scan, population.status_description, population.completion_type_description, population.queued_population_type_description, population.start_time, population.range_count
FROM sys.dm_fts_active_catalogs catalog
CROSS JOIN sys.dm_fts_index_population population
WHERE catalog.database_id = population.database_id
AND catalog.catalog_id = population.catalog_id
AND catalog.database_id = (SELECT dbid FROM sys.sysdatabases WHERE name = DB_NAME());
