Hi,
This is a script which will help to look up the active and inactive virtual log file count.

Insert Into #summary
Select DB_Name(),Status,Count( Status), FileID

SELECT Database_Name,Case When VLF=2 Then 'Active' else 'InActive' End as Virtual_log,VLF_Count,Log_File_ID
FROM #summary

ORDER BY Database_Name,Log_File_ID ;

When was Server Last Restarted
There was a report that we had to put together for the servers that had re-started within the tenure and the probable reason for the restart.
Below query gives you the time the SQL Server Reatrted. This query assumes that the tempdb is created everytime the SQL Server restarts.
SELECT [Name] , CrDate as DateServerRebooted
from sys.sysdatabases
WHERE dbid = 2
Now if you want to further when the SQL Server was stopped and the probable reason for the Server shutdown you have to go to the individual error logs and identify.
