sp_Blitz from http://FirstResponderKit.org
This script checks the health of your SQL Server and gives you a prioritized
to-do list of the most urgent things you should consider fixing.
To learn more, visit http://FirstResponderKit.org where you can download new
versions for free, watch training videos on how it works, get more info on
the findings, contribute your own code, and more.
Known limitations of this version:
- Only Microsoft-supported versions of SQL Server. Sorry, 2005 and 2000.
- If a database name has a question mark in it, some tests will fail. Gotta
love that unsupported sp_MSforeachdb.
- If you have offline databases, sp_Blitz fails the first time you run it,
but does work the second time. (Hoo, boy, this will be fun to debug.)
- @OutputServerName will output QueryPlans as NVARCHAR(MAX) since Microsoft
has refused to support XML columns in Linked Server queries. The bug is now
16 years old! *~ \o/ ~*
Unknown limitations of this version:
- None. (If we knew them, they would be known. Duh.)
Changes - for the full list of improvements and fixes in this version, see:
https://github.com/BrentOzarULTD/SQL-Server-First-Responder-Kit/
Parameter explanations:
@CheckUserDatabaseObjects 1=review user databases for triggers, heaps, etc. Takes more time for more databases and objects.
@CheckServerInfo 1=show server info like CPUs, memory, virtualization
@CheckProcedureCache 1=top 20-50 resource-intensive cache plans and analyze them for common performance issues.
@OutputProcedureCache 1=output the top 20-50 resource-intensive plans even if they did not trigger an alarm
@CheckProcedureCacheFilter ''CPU'' | ''Reads'' | ''Duration'' | ''ExecCount''
@OutputType ''TABLE''=table | ''COUNT''=row with number found | ''MARKDOWN''=bulleted list | ''SCHEMA''=version and field list | ''NONE'' = none
@IgnorePrioritiesBelow 50=ignore priorities below 50
@IgnorePrioritiesAbove 50=ignore priorities above 50
For the rest of the parameters, see http://www.brentozar.com/blitz/documentation for details.

the results from our checks. Throughout the rest of this stored procedure,
we're running a series of checks looking for dangerous things inside the SQL
Server. When we find a problem, we insert rows into #BlitzResults. At the
end, we return these results to the end user.
#BlitzResults has a CheckID field, but there's no Check table. As we do
checks, we insert data into this table, and we manually put in the CheckID.

You can build your own table with a list of checks to skip. For example, you
might have some databases that you don't care about, or some checks you don't
want to run. Then, when you run sp_Blitz, you can specify these parameters:
@SkipChecksDatabase = 'DBAtools',
@SkipChecksSchema = 'dbo',
@SkipChecksTable = 'BlitzChecksToSkip'
Pass in the database, schema, and table that contains the list of checks you
want to skip. This part of the code checks those parameters, gets the list,
and then saves those in a temp table. As we run each check, we'll see if we
need to skip it.
Really anal-retentive users will note that the @SkipChecksServer parameter is
not used. YET. We added that parameter in so that we could avoid changing the
stored proc's surface area (interface) later.

But what if you need to run a query in every individual database?
Hop down to the @CheckUserDatabaseObjects section.
And that's the basic idea! You can read through the rest of the
checks if you like - some more exciting stuff happens closer to the
end of the stored proc, where we start doing things like checking
the plan cache, but those aren't as cleanly commented.
If you'd like to contribute your own check, use one of the check
formats shown above and email it to Help@BrentOzar.com. You don't
have to pick a CheckID or a link - we'll take care of that when we
test and publish the code. Thanks!
