    .Synopsis
    Will create a graphical structure (.png file) that represents SCOM class taxonomy; all SCOM class attributes, properties, hosting relationships, and discovery relationships for a SCOM class.
     
    .DESCRIPTION
    This function will use the GraphViz package to produce a graph-like structure (.png file) that will represent one or more SCOM
    classes and it's full hierarchy which includes parents, attributes, properties, hosting relationships (both hosted and hosting), and any discoveries which are capable of discovering the related classes.
    Any number of SCOM class objects or names may be piped to the function.
 
    This function relies on the following modules. User will be prompted for permissio to install these:
    OpsMgrExtended: available from the PowerShell Gallery here: https://www.powershellgallery.com/packages/OpsMgrExtended
    GraphViz: from the Chocolatey repo. (https://www.graphviz.org/)
    PSGraph: https://github.com/KevinMarquette/PSGraph
 
    .EXAMPLE
    PS C:\> New-SCOMClassGraph -ClassName 'Microsoft.SQLServer.2012.DBEngine'
    .EXAMPLE
    PS C:\> New-SCOMClassGraph -ClassName 'Microsoft.SQLServer.2014.AlwaysOn.DatabaseReplica' -Caching:$False
 
    The above example will generate a new graph even if one already exists in the default storage directory.
    .EXAMPLE
    PS C:\> New-SCOMClassGraph -ClassName 'Microsoft.Windows.Server.6.2.LogicalDisk' -ShowDiscoveries:$false
 
    The above example will create a graph but will not include Discovery relationships.
    NOTE: If you are not seeing discovery data in your graphs it may be because the graphs are cached without discovery data.
    Try using the caching switch to force new graph files to be created. Discovery data will be included by default.
     
    Example: -Caching:$false
    .EXAMPLE
    PS C:\> Get-SCOMClass -Name *sql* | New-SCOMClassGraph -ShowGraph:$false
 
    The above example will create graph files for ALL SQL classes but will not open the graph files in the default application.
    Typically there are a tremendous number of SQL classes in the SQL management packs.
     
    .EXAMPLE
    PS C:\> New-SCOMClassGraph -ID 'ea99500d-8d52-fc52-b5a5-10dcd1e9d2bd'
     
    .EXAMPLE
    PS C:\> (Get-SCOMClassInstance -DisplayName "http://ms01.contoso.com:80/" ).getclasses().Name | New-SCOMClassGraph
 
    The above example will show the class graph for a specific instance of a class type.
     
    .EXAMPLE
    PS C:\> (Get-SCOMClassInstance -DisplayName "SQLEXPRESS" ).getclasses().Name | New-SCOMClassGraph
 
    The above example will show the class graph for a specific instance of a class type.
 
    .EXAMPLE
    PS C:\> New-SCOMClassGraph -ShowIndex
 
    The example above will display an html index page for all of the graph files. The html file will open with the default application.
 
    .EXAMPLE
    PS C:\> Get-SCOMClass | Select Name,Displayname, @{N='ManagementPackName';E={$_.Identifier.Domain[0]} }| Out-GridView -PassThru | New-SCOMClassGraph
 
    This example above is a much fancier way to select one or more class names with the help of GridView. This command will get all SCOM classes in the management group and present Name, DisplayName, and ManagementPackName in GridView for easy browsing, filtering, and selection by the user. Select one or more classes from the Grid View, click OK. The selected class name(s) gets piped into the function: New-SCOMClassGraph
 
    .EXAMPLE
    #Example Script
 
    $int=0
    $arr =@()
    ForEach ($class in (Get-SCOMClass)) {
    $obj = New-Object pscustomobject
    $obj | add-member -name 'Index' -Value $int -MemberType NoteProperty
    $obj | add-member -name 'Name' -Value ($Class.Name) -MemberType NoteProperty
    $obj | add-member -name 'DisplayName' -Value ($class.DisplayName) -MemberType NoteProperty
    $arr+=$obj
    $int++
    }
    $arr | Out-GridView -PassThru | New-SCOMClassGraph -Caching:$false -Combine
 
    This example will present a gridview list of classes for you to select. Multi-select supported to combine numerous classes on a single graph. Be careful, don't overdo it.
 
    .Parameter ClassName
    This is the name of a class. (not the DisplayName)
     
    .Parameter Class
    An Operations Manager class object.
 
    .Parameter ID
    ID of a class.
 
    .Parameter Caching
    This will enable/disable the use of preexisting graphs. If $false, a new graph will be created. If $true, the script will look for an existing graph for the class. If no graph exists, a new one will be created.
     
    .Parameter ShowGraph
    This allows the user to generate the graphs in the designated directory without opening them (with the default application associated to the .png file type)
     
    .Parameter ShowDiscoveries
    This will allow the user to omit the discovery relationships.
     
    .Parameter ShowIndex
    This will display an html index page for all of the graph files. The html file will open with the default application.

    Will standardize all of the aliases in one or more unsealed (.xml) management pack files.
    .DESCRIPTION
    This script will inventory all of the MP reference IDs that can be found in the single file or set of .XML files specified by the InputPath. It will create a customized set of condensed alias acronyms to be standardized across all of the unsealed management packs. It will then replace the aliases in the Manifest as well as throughout the elements where the aliases are used.
    .Parameter InputPath
    This can be a directory or full path to an unsealed management pack .xml file.

    .Synopsis
    This function is designed to launch a SCOM Property Bag PowerShell script. It will output the DataItem to an xml file for inspection.
    .DESCRIPTION
    When authoring and troubleshooting a SCOM Property Bag PowerShell script it is helpful to be able to analyze the resulting DataItem. This script will make this process easier by outputing the DataItem(s) to an XML file. The default output file will have the same path/name as the input file (+.xml). Script must propertly use 'MOM.ScriptAPI' and output the proerty bag.
    Why is this useful? It's easy to output the DataItem to the screen but then it's difficult to read/analyze. If you open the .xml file with a fancy text editor like Notepad++ you can leverage the XMLTools plugin to nicely format the data. This is especially helpful for large property bags.
    Example :
    $api = New-Object -ComObject 'MOM.ScriptAPI'
    $bag = $api.CreatePropertyBag()
    $bag.AddValue('Message',"Some message")
    $api.Return($bag) #This will output the DataItem for analysis
 
    .EXAMPLE
    Show-SCOMPropertyBag -FilePath C:\test\MyScript.ps1
    This will execute C:\test\MyScript.ps1 and output the property bag data of each bag ($Bag assumed to be in the script) to <$env:windir\Temp\><script file name>_<uniquetimestamp>.xml. Individual bags will be returned in a formatted table.
 
    .EXAMPLE
    Show-SCOMPropertyBag -FilePath C:\test\MyScript.ps1 -ShowXML
    This will execute MyScript.ps1 and output the property bag data of each bag ($Bag assumed to be in the script) to <$env:windir\Temp\><script file name>_<uniquetimestamp>.xml and then open the .xml file with the default application.
 
    .EXAMPLE
    Get-ChildItem -Path C:\TestScripts\*.ps1 | Show-SCOMPropertyBag -ShowXML -Format Separate
    This will execute all PowerShell scripts in the path and output the property bag data of each bag ($Bag assumed to be in the script) to <$env:windir\Temp\><script file name>_<uniquetimestamp>.xml and then open the .xml files with the default application.
    Each property bag will be displayed individually to the screen.
 
    .EXAMPLE
    Show-SCOMPropertyBag -FilePath C:\test\MyScript.ps1 -Format Combined -Verbose
    This will execute C:\test\MyScript.ps1 and output the property bag data of each bag ($Bag assumed to be in the script) to <$env:windir\Temp\><script file name>_<uniquetimestamp>.xml.
    All property bag data will be displayed to the screen in one formatted table.
 
    Use -Verbose switch to display output file location.

<#
    .SYNOPSIS
    Operations Manager Powershell script to output the effective monitoring configurations for a specified object ID, group, or Computer name.
    .DESCRIPTION
    Will recursively find contained instances of an object (or group of objects) and output the effective monitoring configurations/settings to individual output files.
    Then will merge all resulting files into one .csv file, delimited by pipes '|', then output all data to Grid View.
    .EXAMPLE
    PS C:\> Export-EffectiveMonitoringConfiguration -SCOMGroupName "All Windows Computers" -TargetFolder "C:\Export\MyConfigFiles" -OutputFileName "AllWindowsComputers_MonitoringConfigs.CSV"
    .EXAMPLE
    PS C:\> Export-EffectiveMonitoringConfiguration -ComputerName "SQL01.contoso.com" -TargetFolder "C:\Export" -OutputFileName "Output.csv"
    .EXAMPLE
    The following example returns the Monitoring object ID of a Windows Computer instance with name: "db01.contoso.com". The ID is then used as a parameter.
 
    PS C:\> $ComputerID = (Get-SCOMClass -name "Microsoft.windows.computer" | Get-SCOMClassInstance | ? {$_.DisplayName -like "db01.contoso.com"}).Id
    PS C:\> Export-EffectiveMonitoringConfiguration -ID $ComputerID -TargetFolder "C:\Export" -OutputFileName "Output.csv"
    .EXAMPLE
    The following example will output all monitoring configuration info for a specific computer to a csv file. There will be no confirmation prompt to proceed.
    Any previously stored DisplayName file will be removed and recreated. This will increase run time of script as it will have to retrieve all of the workflow Displaynames and
    this is very expensive on the SQL database. It will then display that information in GridView. The -PassThru parameter
    will allow the user to filter the view and then export any selected GridView line items to a new csv file named "FilteredOutput.csv"
 
    PS C:\> Export-EffectiveMonitoringConfiguration -ComputerName "win01.contoso.com" -TargetFolder "C:\Export" -OutputFileName "WIN01_Output.csv" -NoConfirm -ClearCache -NoGridView
    PS C:\> Import-Csv 'C:\Export\Merged_WIN01_Output.csv' -Delimiter '|' | Out-GridView -PassThru | Export-Csv -Path 'C:\Export\FilteredOutput.csv' -NoTypeInformation -Force

    Blog: : https://blogs.msdn.microsoft.com/tysonpaul/2018/07/18/scomhelper-powershell-module-a-scom-admins-best-friend/
    Requires : Operations Manager Powershell Console
    Version : 1.16
    Original Date: 7-25-2014
    History
    2018.09.14: Modified 'ID' and 'ComputerName' parameters to allow arrays.
    Added 'Path' column.
    2018.04.06: Added column to output: Rule/Monitor DisplayName
    2017.11.28: Fixed paramter types.
    2017.10.11: Added ability to specify object ID or single computer name. Improved Help content. Improved output formatting.
    2014.8.6: Fixed output file name/path problem.
    .PARAMETER -ComputerName
    Accepts a single FQDN (Fully Qualified Domain Name) name of an monitored computer.
    .PARAMETER -ID
    Accepts a single guid. Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).
    .PARAMETER -SCOMGroupName
    Accepts a single group name.
    .PARAMETER -TargetFolder
    The full path to where the script should output the configuration files.
    .PARAMETER -OutputFileName
    The name of the complete output file in which all other configuration files will be compiled.
    .PARAMETER -NoConfirm
    Switch. Will not prompt user for confirmation to proceed. (Caution should be taken when targeting large groups.)
    .PARAMETER -NoGridView
    Switch. Will not display configuration in PowerShell GridView
    .PARAMETER -ClearCache
    Switch. Will delete any existing DisplayName file. This is a file that is saved in the $ENV:TEMP path. It will save a list of
    workflow Names and DisplayNames from previous executions of this script. This will significantly speed up the runtime of the script.
    This option is only useful if management packs have been updated and DisplayNames of workflows have been modified since the script
    was last run. When enabled, this parameter will force the script to retrieve all of the DisplayNames from the SDK instead of the locally stored file.

#######################################################################

<#
    .SYNOPSIS
    This script will get all rule and monitor knowledge article content and output the information to separate files (Rules.html and Monitors.html) in the output folder path specified.
 
    .PARAMETER OutFolder
    The output folder path where output files will be created. Must be a container/directory, not a file.
 
    .PARAMETER ManagementPack
    A collection/array of one or more management pack objects.
 
    .PARAMETER MgmtServerFQDN
    Alias: ManagementServer
    Fully Qualified Domain Name of the SCOM management server.
 
    .PARAMETER NoKnowledgeExclude
    By default ALL workflows will be included in the output files. Enable this switch to exclude workflows which have no Knowledge Article content.
 
    .PARAMETER ExportCSV
    Export results to CSV files instead of default format (.html)
 
    .PARAMETER Topic
    This will customize the name of the output files. Useful when dumping multiple sets to the same output folder.
 
    .PARAMETER ShowResult
    Will open the Windows file Explorer to show output files.
 
    .EXAMPLE
    (Get-SCOMManagementPack -Name *.AD.*) | Export-SCOMKnowledge -OutFolder 'C:\MyReports' -Topic "AD_" -ShowResult
    In the example above the variable will be assigned a collection of all management pack objects with ".AD." in the name.
    That subset/collection of management pack objects will be passed into the script. The script will output workflow details for all Rules and Monitors contained in ALL management packs within that set.
    The output file names will be: "AD_Rules.html" and "AD_Monitors.html". Finally the script will open Windows File Explorer to the location of the output directory.
 
    .Example
    PS C:\> Export-SCOMKnowledge -OutFolder 'C:\Export' -ManagementPack (Get-SCOMManagementPack -Name "*ad.*") -Filter '201[0-6]'
    The command above will output all rules/monitors from management packs which contain 'ad.' in the Name and which contain '201x' in the Name or DisplayName of the workflow where 'x' represents any single digit 0-6 .
 
    .EXAMPLE
    PS C:\> Export-SCOMKnowledge -OutFolder "C:\Temp" -ManagementPack (Get-SCOMManagementPack -Name *SQL*) -Topic "SQL_Packs_"
    The command above will output workflow details for all Rules and Monitors contained in ALL management packs with "SQL" in the management pack Name.
    The output file names will be: "SQL_Packs_Rules.html" and "SQL_Packs_Monitors.html"
 
    .EXAMPLE
    PS C:\> Export-SCOMKnowledge -OutFolder "C:\MyReports" -ManagementServer "ms01.contoso.com" -NoKnowledgeExclude
    In the example above, the command will connect to management server: "ms01.contoso.com", will output workflow details for all Rules and Monitors (only if they contain a Knowledge Article) to two separate files in the specified folder. The output file names will be: "Rules.html" and "Monitors.html"
 
    .Example
    PS C:\> Export-SCOMKnowledge -OutFolder 'C:\Export' -ManagementPack (Get-SCOMManagementPack -Name "*ad.*") -Filter '(?=200[0-8])((?!Monitoring).)*$'
    The command above will output all rules/monitors from management packs which contain 'ad' in the Name and which contain '200x' in the Name or DisplayName of the workflow where 'x' is numbers 1-8 but excluding workflows that contain 'monitoring'.
 
    .Example
    This is a way to use management pack files (.mp and .xml) from a directory path with specific topics.
    The below script example will use management pack files which names match the array of Topics.
 
    ##---- CONFIGURE THESE VARIABLES ----##
    # Location of management pack files
    $inDir = 'C:\Program Files (x86)\System Center Management Packs\'
    # Output directory
    $outDir = 'C:\'
    # Management pack file names which match these strings will be selected
    $topics = "DHCP,DNS,FileServices,GroupPolicy,DFS,FileReplication"
    ##---- CONFIGURE THESE VARIABLES ----##
 
    $FilePaths =@()
    $h = @{}
    # Will export data for each management pack file name matching the topic name.
    ForEach ($topic in $topics.Split(',')){
    Write-Host "Topic: $topic" -BackgroundColor Black -ForegroundColor Yellow
    $FilePaths = Get-ChildItem -Recurse -Include "*$topic*.mp*","*$topic*.xml*" -File -Path $inDir | Select fullname
    $FilePaths | ForEach {$h.(Split-Path $_.FullName -Leaf) = $_.FullName }
    If (!($h.Count)){ Continue;} #If no matching file found, skip to next topic
    $h.Keys
    ""
    $MPs = (Get-SCOMManagementPack -ManagementPackFile ($h.Values | % {$_} ) )
    Export-SCOMKnowledge -OutFolder $outDir -ManagementPack $MPs -Topic $Topic
    }

    History:
    2017/12/05: Added Topic parameter to customize output file names. Added ShowResult switch.
    2017/10/16: Added support for regex filtering on DisplayName or Name of monitors/rules.
    2016/05/03: Added option to export to CSV. Although embedded tables in the KnowledgeArticle don't convert very well.
    2016/04/26: Improved formatting of output files. Now includes embedded parameter tables and restored article href links.
    2016/04/26: Fixed script to accept ManagementPack pipeline input

    As with all scripts I post, this is provided AS-IS without warrenty so please test first and use at your own risk.
 
    What this version of the script will give you:(Some of these are just features which are carried over from the original, many are added)
 
    01. Version/Service Pack/Edition of SQL for each SCOM DB Server
 
    02. Disk Space Info for Ops DB, DW DB, and associated Temp DB's
 
    03. Database Backup Status for all DB's except Temp.
 
    04. Top 25 Largest Tables for Ops DB and DW DB
 
    05. Number of Events Generated Per Day (Ops DB)
 
    06. Top 10 Event Generating Computers (Ops DB)
 
    07. Top 25 Events by Publisher (Ops DB)
 
    08. Number of Perf Insertions Per Day (Ops DB)
 
    09. Top 25 Perf Insertions by Object/Counter Name (Ops DB)
 
    10. Top 25 Alerts by Alert Count
 
    11. Alerts with a Repeat Count higher than 200
 
    12. Stale State Change Data
 
    13. Top 25 Monitors Changing State in the last 7 Days
 
    14. Top 25 Monitors Changing State By Object
 
    15. Ops DB Grooming History
 
    16. Snapshot of DW Staging Tables
 
    17. DW Grooming Retention
 
    18. Management Server checks (Works well on prem, seems to have some issues with gateways due to remote calls-if you see some errors flash by have no fear though I wouldn't necessarily trust the results coming back from a Gateway server in the report depending on firewall settings)
 
    19. Daily KPI
 
    20. MP's Modified in the Last 24 hours
 
    21. Overrides in Default MP Check
 
    22. Unintialized Agents
 
    23. Agent Stats (Healthy, Warning, Critical, Unintialized, Total)
 
    24. Agent Pending Management Summary
 
    25. Alert Summary
 
    26. Servers in Maintenance Mode
