sp_blitz shows "Last good DBCC CHECKDB over 2 weeks old"

Question

When I run sp_blitz, I see

-[ RECORD 5 ]-------------------------
Priority          | 1
FindingsGroup     | Reliability
Finding           | Last good DBCC CHECKDB over 2 weeks old
DatabaseName      | model

QueryPlan         | NULL
QueryPlanFiltered | NULL
CheckID           | 68
-[ RECORD 6 ]-------------------------

However, I just ran DBCC CHECKDB.

Answer 1

The DatabaseName is different in the output there. You have to run DBCC CHECKDB for each database.

DBCC CHECKDB (model);
DBCC CHECKDB (msdb);
DBCC CHECKDB (master);

By default, DBCC CHECKDB runs on the current database. If you connected without specifying a database, you're likely connected to the default database for your user. You can see your current database with

SELECT DB_NAME();

You can see all of your users' default databases with,

SELECT name, default_database_name FROM sys.server_principals;

You don't have to explicitly run it against the Resource Database, from the docs

However, when DBCC CHECKDB is executed against the master database, a second CHECKDB is also run internally on the Resource database.
