Hello Clifton,
DBACOCKPIT is the right tx for monitoring DBs.
For SQL Server installations there are master db, tempdb, model db and SAPSID DB as you may know.
All DBs can be monitored from DBACOCKPIT as you can see below.
Cristina is pointing the same screen, too.
You can go to the same screen using ST04, DB02, DB12, DB13 also.
Regards,
Yuksel AKCINAR
