When people hand us a SQL Server and ask us to take it over, we need to do a fast health check. We need to put on our latex gloves, do a little poking around, and discover the dirty secrets before they catch us by surprise. That’s where our sp_Blitz script comes in: it helps you rapidly assess configuration, security, health, and performance issues. We organize the results in a prioritized list and give you simple explanations of each risk, plus a column of links that you can copy/paste into your browser for more information about each issue.
The sp_Blitz and sp_BlitzUpdate stored procedure code is below. You can copy/paste it into SSMS and run it to create the stored procs, and then just EXEC sp_Blitz to run the checks. On larger servers, it may take a couple of minutes for some of the more detailed tests, like untrusted foreign keys, but this shouldn’t cause any blocking.
Copy/paste the below script or download it here.

sp_Blitz v5 - December 18, 2011
(C) 2011, Brent Ozar PLF, LLC
To learn more, visit http://www.BrentOzar.com/go/blitz where you can download
new versions for free, watch training videos on how it works, get more info on
the findings, and more.
Known limitations of this version:
- No support for offline databases. If you can't query some of your databases,
this script will fail. That's fairly high on our list of things to improve
since we like mirroring too.
- SQL Server 2000 not quite supported (yet, but we're coding it in).
Unknown limitations of this version:
- None. (If we knew them, they'd be known. Duh.)
Changes in v5 Dec 18 2011:
- John Miner suggested tweaking checkid 48 and 56, the untrusted constraints
and keys, to look for is_not_for_replication = 0 too. This filters out
constraints/keys that are only used for replication and don't need to
be trusted.
- Ned Otter caught a bug in the URL for check 7, startup stored procs.
- Scott (Anon) recommended using SUSER_SNAME(0x01) instead of 'sa' when
checking for job ownership, database ownership, etc.
- Martin Schmidt http://www.geniiius.com/blog/ caught a bug in checkid 1 and
contributed code to catch databases that had never been backed up.
- Added parameter for @CheckProcedureCache. When set to 0, we skip the checks
that are typically the slowest on servers with lots of memory. I'm
defaulting this to 0 so more users can get results back faster.
Changes in v4 Nov 1 2011:
- Andreas Schubert caught a typo in the explanations for checks 15-17.
- K. Brian Kelley @kbriankelley added checkid 57 for SQL Agent jobs set to
start automatically on startup.
- Added parameter for @CheckUserDatabaseObjects. When set to 0, we skip the
checks that are typically the slowest on large servers, the user
database schema checks for things like triggers, hypothetical
indexes, untrusted constraints, etc.
Changes in v3 Oct 16 2011:
- David Tolbert caught a bug in checkid 2. If some backups had failed or
been aborted, we raised a false alarm about no transaction log backups.
- Fixed more bugs in checking for SQL Server 2005. (I need more 2005 VMs!)
Changes in v2 Oct 14 2011:
- Ali Razeghi http://www.alirazeghi.com added checkid 55 looking for
databases owned by <> SA.
- Fixed bugs in checking for SQL Server 2005 (leading % signs)
Explanation of priority levels:
1 - Critical risk of data loss. Fix this ASAP.
10 - Security risk.
20 - Security risk due to unusual configuration, but requires more research.
50 - Reliability risk.
60 - Reliability risk due to unusual configuration, but requires more research.
100 - Performance risk.
110 - Performance risk due to unusual configuration, but requires more research.
200 - Informational.
