	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 (including server info, excluding security findings) | ''SCHEMA''=version and field list | ''XML'' =table output as XML | ''NONE'' = none
	@IgnorePrioritiesBelow		50=ignore priorities below 50
	@IgnorePrioritiesAbove		50=ignore priorities above 50
	For the rest of the parameters, see https://www.BrentOzar.com/blitz/documentation for details.

	This script checks your backups to see how much data you might lose when
	this server fails, and how long it might take to recover.

	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.

	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:

	@HoursBack INT = 168		How many hours of history to examine, back from now.
								You can check just the last 24 hours of backups, for example.
	@MSDBName NVARCHAR(255) 	You can restore MSDB from different servers and check them
								centrally. Also useful if you create a DBA utility database
								and merge data from several servers in an AG into one DB.
	@RestoreSpeedFullMBps INT	By default, we use the backup speed from MSDB to guesstimate
								how fast your restores will go. If you have done performance
								tuning and testing of your backups (or if they horribly go even
								slower in your DR environment, and you want to account for
								that), then you can pass in different numbers here.
	@RestoreSpeedDiffMBps INT	See above.
	@RestoreSpeedLogMBps INT	See above.

	This script displays your most resource-intensive queries from the plan cache,
	and points to ways you can tune these queries to make them faster.


	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:
	 - SQL Server 2008 and 2008R2 have a bug in trigger stats, so that output is
	   excluded by default.
	 - @IgnoreQueryHashes and @OnlyQueryHashes require a CSV list of hashes
	   with no spaces between the hash values.

	Unknown limitations of this version:
	 - May or may not be vulnerable to the wick effect.

	Changes - for the full list of improvements and fixes in this version, see:

This script analyzes the design and performance of your indexes.

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.
 - Index create statements are just to give you a rough idea of the syntax. It includes filters and fillfactor.
 --        Example 1: index creates use ONLINE=? instead of ONLINE=ON / ONLINE=OFF. This is because it is important 
           for the user to understand if it is going to be offline and not just run a script.
 --        Example 2: they do not include all the options the index may have been created with (padding, compression
           filegroup/partition scheme etc.)
 --        (The compression and filegroup index create syntax is not trivial because it is set at the partition 
           level and is not trivial to code.)
 - Does not advise you about data modeling for clustered indexes and primary keys (primarily looks for signs of insanity.)

Unknown limitations of this version:
 - We knew them once, but we forgot.

    This script checks for and analyzes deadlocks from the system health session or a custom extended event path

    Variables you can use:

        @DatabaseName: If you want to filter to a specific database

        @StartDate: The date you want to start searching on, defaults to last 7 days

        @EndDate: The date you want to stop searching on, defaults to current date

        @ObjectName: If you want to filter to a specific able.
                     The object name has to be fully qualified ''Database.Schema.Table''

        @StoredProcName: If you want to search for a single stored proc
                     The proc name has to be fully qualified ''Database.Schema.Sproc''

        @AppName: If you want to filter to a specific application

        @HostName: If you want to filter to a specific host

        @LoginName: If you want to filter to a specific login

        @EventSessionName: If you want to point this at an XE session rather than the system health session.

        @TargetSessionType: Can be ''ring_buffer'' or ''event_file''. Leave NULL to auto-detect.

        @OutputDatabaseName: If you want to output information to a specific database

        @OutputSchemaName: Specify a schema name to output information to a specific Schema

        @OutputTableName: Specify table name to to output information to a specific table

    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 SQL Server 2012 and newer is supported
     - If your tables have weird characters in them (https://en.wikipedia.org/wiki/List_of_xml_and_HTML_character_entity_references) you may get errors trying to parse the xml.
       I took a long look at this one, and:
        1) Trying to account for all the weird places these could crop up is a losing effort.
        2) Replace is slow af on lots of xml.

    Unknown limitations of this version:
     - None.  (If we knew them, they would be known. Duh.)

This script gives you a prioritized list of why your SQL Server is slow right now.

This is not an overall health check - for that, check out sp_Blitz.

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. It
   may work just fine on 2005, and if it does, hug your parents. Just don''t
   file support issues if it breaks.
 - If a temp table called #CustomPerfmonCounters exists for any other session,
   but not our session, this stored proc will fail with an error saying the
   temp table #CustomPerfmonCounters does not exist.
 - @OutputServerName is not functional yet.
 - If @OutputDatabaseName, SchemaName, TableName, etc are quoted with brackets,
   the write to table may silently fail. Look, I never said I was good at this.

Unknown limitations of this version:
 - None. Like Zombo.com, the only limit is yourself.

Changes - for the full list of improvements and fixes in this version, see:
