Our database inspection once a quarter, so often use the following script
- 1. Check the version information database
the SELECT @@ Version
--2. See all database names and sizes
Exec sp_helpdb
--3. Check your operating system of the machine where the database parameters
Exec master..xp_msver
--4. View the database startup parameters
. --5 view start time database
SELECT Convert (VARCHAR (30), login_time, 120)
from master..sysprocesses. 1 WHERE SPID =
--6 view the database server name.
SELECT 'the Name Server:' + LTRIM (@@ ServerName)
. --7 View database instance name
the SELECT 'instance:' + LTRIM (@@ SERVICENAME)
--8 database disk space it uses the information.
Exec sp_spaceused
- 9 log file size and use.
dbcc SQLPERF (LOGSPACE)
- 10. table disk space usage information
SELECT
@@ total_read [number of disk reads],

--12. acquires I / O operation
--13. See operation of CPU activity and
SELECT

--14. checks the lock-and-wait
Exec the sp_lock
--15. deadlock check
exec sp_who
