PSBlitz.ps1

<# 
.SYNOPSIS
 Outputs SQL Server health and performance diagnostics data to either Excel or HTML, 
 and saves execution plans and deadlock graphs as .sqlplan and .xdl files.

.DESCRIPTION
 Outputs the following to an Excel spreadsheet or to an HTML report:

    Instance information
    Wait stats - from sp_BlitzFirst
	Currently opened transactions (if any)
    Currently running queries - from sp_BlitzWho
    Instance health-related findings - from sp_Blitz
    tempdb size and usage information per object and session
    Index-related issues and recommendations - from sp_BlitzIndex
    Top 10 most resource intensive queries - from sp_BlitzCache
    Deadlock related information from the past 15 days - from sp_BlitzLock
	Information about all databases and their files or for a single database in 
	case of a database-specific check
	Query Store information in the case of a database-specific check on an eligible database - from 
	sp_BlitzQueryStore
    Statistics details for a given database - in the case of database-specific check or if a database 
	accounts for at least 2/3 of the sp_BlitzCache data
    Index Fragmentation information for a given database - in the case of database-specific check or if 
	a database accounts for at least 2/3 of the sp_BlitzCache data

 Note: If the execution of PSBlitz took longer than 15 minutes up until the call to sp_BlitzLock, the timeframe for 
 sp_BlitzLock will be narrowed down to the last 7 days in order to keep execution time within a reasonable amount.

 Exports the following files:

    Execution plans (as .sqlplan files) - from the same dataset generated by sp_BlitzCache
    Execution plans (as .sqlplan files) - from the sample execution plans provided by sp_BlitzIndex @Mode = 0 
	and sp_BlitzIndex @Mode = 4 for missing index suggestions (only on SQL Server 2019)
    Execution plans (as .sqlplan files) of currently running sessions - from the same dataset generated by sp_BlitzWho
    Deadlock graphs (as .xdl files) - from the same dataset generated by sp_BlitzLock
	Execution plans (as .sqlplan files) - from sp_BlitzLock if any of the execution plans involved in deadlocks are still
	in the plan cache at the time of the check
	Execution plans (as .sqlplan files) - from sp_BlitzQueryStore in the case of a database-specific check 
	on an eligible database

 PSBlitz.ps1 uses slightly modified, non-stored procedure versions, of the following components from Brent Ozar's 
 SQL Server First Responder Kit:

    sp_Blitz
    sp_BlitzCache
    sp_BlitzFirst
    sp_BlitzIndex
    sp_BlitzLock
    sp_BlitzWho
	sp_BlitzQueryStore
 
 Aside from the above scripts, PSBlitz also runs the following scripts to return sp_BlitzWho data, instance and resource 
 information, index fragmentation and stats info, database and database files info, as well as TempDB usage:

    GetDbInfo.sql
    GetBlitzWhoData.sql
    GetInstanceInfo.sql
	GetAzureSQLDBInfo.sql
    GetTempDBUsageInfo.sql
	GetStatsInfoForWholeDB.sql
	GetIndexInfoForWholeDB.sql

 Prerequisites 
    
    If you want the report to be in Excel format, then the MS Office suite needs to be installed on the machine where 
	you're executing PSBlitz, otherwise use the HTML format.
	PSBlitz will auto-default to HTML output on when ran on a host that does not have the MS Office suite installed.
	Sufficient permissions to query DMVs, server state, and get database objects' definitions.

	You don't need to have any of the sp_Blitz stored procedures present on the instance that you're executing PSBlitz.ps1 for, 
	all the scripts are contained in the PSBlitz\Resources directory in non-stored procedure format.

 Execution

    You can run PSBlitz.ps1 by simply right-clicking on the script and then clicking on "Run With PowerShell" which will execute 
    the script in interactive mode, prompting you for the required input.

    Otherwise you can navigate to the directory where the script is in PowerShell and execute it by providing parameters 
	and appropriate values.

.PARAMETER ServerName
 Accepts either HostName\InstanceID (for named instances), HostName,Port when using a port number instead of an instance ID, 
 or just HostName for default instances. If you provide either ? or Help as a value for -ServerName, 
 the script will return a brief help menu.

.PARAMETER SQLLogin
 The name of the SQL login used to run the script. If not provided, the script will use integrated security.

.PARAMETER SQLPass
 The password for the SQL login provided via the -SQLLogin parameter, omit if -SQLLogin was not used.

.PARAMETER IsIndepth
 Providing Y as a value will tell PSBlitz.ps1 to run a more in-depth check against the instance/database. 
 Omit for default check.

.PARAMETER CheckDB
 Used to provide the name of a specific database against which sp_BlitzIndex, sp_BlitzCache, 
 and sp_BlitzLock will be ran. Omit to run against the whole instance.
 Also used to provide the name of the Azure SQL DB database.

.PARAMETER CacheTop
 Used to specify if more/less than the default top 10 queries should be returned for the 
 sp_BlitzCache step. Only works for HTML output (-ToHTM Y).

.PARAMETER CacheMinutesBack
 Used to specify how many minutes back to begin plan cache analysis. 
 Defaults to entire contents of the plan cache since instance startup.
 In order to avoid missing the desired timeframe, the value is dynamically adjusted based on 
 the runtime of PSBlitz up until the plan cache analysis point.

.PARAMETER OutputDir
 Used to provide a path where the output directory should be saved to. Defaults to PSBlitz.ps1's directory 
 if not specified or a non-existent path is provided.

.PARAMETER ToHTML
 Providing Y as a value will tell PSBlitz.ps1 to output the report as HTML instead of an Excel file. 
 This is perfect when running PSBlitz from a machine that doesn't have Office installed.

.PARAMETER ZipOutput
 Providing Y as a value will tell PSBlitz.ps1 to also create a zip archive of the output files.

.PARAMETER BlitzWhoDelay
 Used to sepcify the number of seconds between each sp_BlitzWho execution. Defaults to 10 if not specified.

.PARAMETER ConnTimeout
 Can be used to increased the timeout limit in seconds for connecting to SQL Server. Defaults to 15 seconds if not specified.

.PARAMETER MaxTimeout
 Can be used to set a higher timeout for sp_BlitzIndex and Stats and Index info retrieval. Defaults to 1000 (16.6 minutes)

.PARAMETER MaxUsrDBs
 Can be used to tell PSBlitz to raise the limit of user databases based on which index-related info is 
 limited to only the "loudest" database in the cache results. Defaults to 50 - only change it if you're using using HTML output
 and have enough RAM to handle the increased data that PS will have to process.

.PARAMETER DebugInfo
 Switch used to get more information for debugging and troubleshooting purposes.
