function Get-DbaAgentJobHistory {
    <#
    .SYNOPSIS
        Gets execution history of SQL Agent Job on instance(s) of SQL Server.
 
    .DESCRIPTION
        Get-DbaAgentJobHistory returns all information on the executions still available on each instance(s) of SQL Server submitted.
        The cleanup of SQL Agent history determines how many records are kept.

        https://msdn.microsoft.com/en-us/library/microsoft.sqlserver.management.smo.agent.jobhistoryfilter(v=sql.120).aspx
 
    .PARAMETER SqlInstance
        The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.
 
    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
    .PARAMETER Job
        The name of the job from which the history is wanted. If unspecified, all jobs will be processed.
 
    .PARAMETER ExcludeJob
        The job(s) to exclude - this list is auto-populated from the server
 
    .PARAMETER StartDate
        The DateTime starting from which the history is wanted. If unspecified, all available records will be processed.
 
    .PARAMETER EndDate
        The DateTime before which the history is wanted. If unspecified, all available records will be processed.
 
    .PARAMETER ExcludeJobSteps
        Use this switch to discard all job steps, and return only the job totals
 
    .PARAMETER WithOutputFile
        Use this switch to retrieve the output file (only if you want step details). Bonus points, we handle the quirks
        of SQL Agent tokens to the best of our knowledge (https://technet.microsoft.com/it-it/library/ms175575(v=sql.110).aspx)
 
    .PARAMETER JobCollection
        An array of SMO jobs
 
    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Get-DbaAgentJobHistory -SqlInstance localhost
 
        Returns all SQL Agent Job execution results on the local default SQL Server instance.
 
    .EXAMPLE
        PS C:\> Get-DbaAgentJobHistory -SqlInstance localhost, sql2016
 
        Returns all SQL Agent Job execution results for the local and sql2016 SQL Server instances.
 
    .EXAMPLE
        PS C:\> 'sql1','sql2\Inst2K17' | Get-DbaAgentJobHistory
 
        Returns all SQL Agent Job execution results for sql1 and sql2\Inst2K17.
 
    .EXAMPLE
        PS C:\> Get-DbaAgentJobHistory -SqlInstance sql2\Inst2K17 | Select-Object *
 
        Returns all properties for all SQl Agent Job execution results on sql2\Inst2K17.
 
    .EXAMPLE
        PS C:\> Get-DbaAgentJobHistory -SqlInstance sql2\Inst2K17 -Job 'Output File Cleanup'
 
        Returns all properties for all SQl Agent Job execution results of the 'Output File Cleanup' job on sql2\Inst2K17.
 
    .EXAMPLE
        PS C:\> Get-DbaAgentJobHistory -SqlInstance sql2\Inst2K17 -Job 'Output File Cleanup' -WithOutputFile
 
        Returns all properties for all SQl Agent Job execution results of the 'Output File Cleanup' job on sql2\Inst2K17,
        with additional properties that show the output filename path
 
    .EXAMPLE
        PS C:\> Get-DbaAgentJobHistory -SqlInstance sql2\Inst2K17 -ExcludeJobSteps
 
        Returns the SQL Agent Job execution results for the whole jobs on sql2\Inst2K17, leaving out job step execution results.
 
    .EXAMPLE
        PS C:\> Get-DbaAgentJobHistory -SqlInstance sql2\Inst2K17 -StartDate '2017-05-22' -EndDate '2017-05-23 12:30:00'
 
        Returns the SQL Agent Job execution results between 2017/05/22 00:00:00 and 2017/05/23 12:30:00 on sql2\Inst2K17.
 
    .EXAMPLE
        PS C:\> Get-DbaAgentJob -SqlInstance sql2016 | Where-Object Name -Match backup | Get-DbaAgentJobHistory
 
        Gets all jobs with the name that match the regex pattern "backup" and then gets the job history from those. You can also use -Like *backup* in this example.
