READ ME - Important options for executing BPCheck

Set @duration to the number of seconds between data collection points regarding perf counters, waits and latches. 
	Duration must be between 10s and 255s (4m 15s), with a default of 90s.
Set @ptochecks to OFF if you want to skip more performance tuning and optimization oriented checks.
Uncomment @custompath below and set the custom desired path for .ps1 files. 
	If not, default location for .ps1 files is the Log folder.
Set @allow_xpcmdshell to OFF if you want to skip checks that are dependant on xp_cmdshell. 
	Note that original server setting for xp_cmdshell would be left unchanged if tests were allowed.
Set @spn_check to OFF if you want to skip SPN checks.
Set @diskfrag to ON if you want to check for disk physical fragmentation. 
	Can take some time in large disks. Requires elevated privileges.
Set @ixfrag to ON if you want to check for index fragmentation. 
	Can take some time to collect data depending on number of databases and indexes, as well as the scan mode chosen in @ixfragscanmode.
Set @ixfragscanmode to the scanning mode you prefer. 
	More detail on scanning modes available at http://msdn.microsoft.com/en-us/library/ms188917.aspx
Set @logdetail to OFF if you want to get just the summary info on issues in the Errorlog, rather than the full detail.
Set @bpool_consumer to OFF if you want to list what are the Buffer Pool Consumers from Buffer Descriptors. 
	Mind that it may take some time in servers with large caches.
Set @gen_scripts to ON if you want to generate index related scripts.
	These include drops for Duplicate, Redundant, Hypothetical and Rarely Used indexes, as well as creation statements for FK and Missing Indexes.
Set @dbScope to the appropriate list of database IDs if there's a need to have a specific scope for database specific checks.
	Valid input should be numeric value(s) between single quotes, as follows: '1,6,15,123'
	Leave NULL for all databases

This code and information are provided "AS IS" without warranty of any kind, either expressed or implied.
Furthermore, the author or Microsoft shall not be liable for any damages you may sustain by using this information, whether direct, indirect, special, incidental or consequential, even if it has been advised of the possibility of such damages.
			
IMPORTANT pre-requisites:
- Only a sysadmin/local host admin will be able to perform all checks.
- If you want to perform all checks under non-sysadmin credentials, then that login must be:
	Member of serveradmin server role or have the ALTER SETTINGS server permission; 
	Member of MSDB SQLAgentOperatorRole role, or have SELECT permission on the sysalerts table in MSDB;
	Granted EXECUTE permissions on the following extended sprocs to run checks: sp_OACreate, sp_OADestroy, sp_OAGetErrorInfo, xp_enumerrorlogs, xp_fileexist and xp_regenumvalues;
	Granted EXECUTE permissions on xp_msver;
	Granted the VIEW SERVER STATE permission;
	Granted the VIEW DATABASE STATE permission;
	Granted EXECUTE permissions on xp_cmdshell or a xp_cmdshell proxy account should exist to run checks that access disk or OS security configurations.
	Member of securityadmin role, or have EXECUTE permissions on sp_readerrorlog. 
 Otherwise some checks will be bypassed and warnings will be shown.
- Powershell must be installed to run checks that access disk configurations, as well as allow execution of remote signed or unsigned scripts.

			-- ACCESS_METHODS_HOBT_VIRTUAL_ROOT = This latch is used to access the metadata for an index that contains the page ID of the index's root page. Contention on this latch can occur when a B-tree root page split occurs (requiring the latch in EX mode) and threads wanting to navigate down the B-tree (requiring the latch in SH mode) have to wait. This could be from very fast population of a small index using many concurrent connections, with or without page splits from random key values causing cascading page splits (from leaf to root).
			-- ACCESS_METHODS_HOBT_COUNT = This latch is used to flush out page and row count deltas for a HoBt (Heap-or-B-tree) to the Storage Engine metadata tables. Contention would indicate *lots* of small, concurrent DML operations on a single table.

			-- ACCESS_METHODS_DATASET_PARENT and ACCESS_METHODS_SCAN_RANGE_GENERATOR = These two latches are used during parallel scans to give each thread a range of page IDs to scan. The LATCH_XX waits for these latches will typically appear with CXPACKET waits and PAGEIOLATCH_XX waits (if the data being scanned is not memory-resident). Use normal parallelism troubleshooting methods to investigate further (e.g. is the parallelism warranted? maybe increase 'cost threshold for parallelism', lower MAXDOP, use a MAXDOP hint, use Resource Governor to limit DOP using a workload group with a MAX_DOP limit. Did a plan change from index seeks to parallel table scans because a tipping point was reached or a plan recompiled with an atypical SP parameter or poor statistics? Do NOT knee-jerk and set server MAXDOP to 1 – that's some of the worst advice I see on the Internet.);
			-- NESTING_TRANSACTION_FULL  = This latch, along with NESTING_TRANSACTION_READONLY, is used to control access to transaction description structures (called an XDES) for parallel nested transactions. The _FULL is for a transaction that's 'active', i.e. it's changed the database (usually for an index build/rebuild), and that makes the _READONLY description obvious. A query that involves a parallel operator must start a sub-transaction for each parallel thread that is used – these transactions are sub-transactions of the parallel nested transaction. For contention on these, I'd investigate unwanted parallelism but I don't have a definite "it's usually this problem". Also check out the comments for some info about these also sometimes being a problem when RCSI is used.

			-- FGCB_ADD_REMOVE = FGCB stands for File Group Control Block. This latch is required whenever a file is added or dropped from the filegroup, whenever a file is grown (manually or automatically), when recalculating proportional-fill weightings, and when cycling through the files in the filegroup as part of round-robin allocation. If you're seeing this, the most common cause is that there's a lot of file auto-growth happening. It could also be from a filegroup with lots of file (e.g. the primary filegroup in tempdb) where there are thousands of concurrent connections doing allocations. The proportional-fill weightings are recalculated every 8192 allocations, so there's the possibility of a slowdown with frequent recalculations over many files.

			-- ACCESS_METHODS_HOBT_VIRTUAL_ROOT = This latch is used to access the metadata for an index that contains the page ID of the index's root page. Contention on this latch can occur when a B-tree root page split occurs (requiring the latch in EX mode) and threads wanting to navigate down the B-tree (requiring the latch in SH mode) have to wait. This could be from very fast population of a small index using many concurrent connections, with or without page splits from random key values causing cascading page splits (from leaf to root).
			-- ACCESS_METHODS_HOBT_COUNT = This latch is used to flush out page and row count deltas for a HoBt (Heap-or-B-tree) to the Storage Engine metadata tables. Contention would indicate *lots* of small, concurrent DML operations on a single table.

			-- ACCESS_METHODS_DATASET_PARENT and ACCESS_METHODS_SCAN_RANGE_GENERATOR = These two latches are used during parallel scans to give each thread a range of page IDs to scan. The LATCH_XX waits for these latches will typically appear with CXPACKET waits and PAGEIOLATCH_XX waits (if the data being scanned is not memory-resident). Use normal parallelism troubleshooting methods to investigate further (e.g. is the parallelism warranted? maybe increase 'cost threshold for parallelism', lower MAXDOP, use a MAXDOP hint, use Resource Governor to limit DOP using a workload group with a MAX_DOP limit. Did a plan change from index seeks to parallel table scans because a tipping point was reached or a plan recompiled with an atypical SP parameter or poor statistics? Do NOT knee-jerk and set server MAXDOP to 1 – that's some of the worst advice I see on the Internet.);
			-- NESTING_TRANSACTION_FULL  = This latch, along with NESTING_TRANSACTION_READONLY, is used to control access to transaction description structures (called an XDES) for parallel nested transactions. The _FULL is for a transaction that's 'active', i.e. it's changed the database (usually for an index build/rebuild), and that makes the _READONLY description obvious. A query that involves a parallel operator must start a sub-transaction for each parallel thread that is used – these transactions are sub-transactions of the parallel nested transaction. For contention on these, I'd investigate unwanted parallelism but I don't have a definite "it's usually this problem". Also check out the comments for some info about these also sometimes being a problem when RCSI is used.
