NAME Get-DbaErrorLog
SYNOPSIS
Gets the "SQL Error Log" of an instance
SYNTAX
Get-DbaErrorLog [[-SqlInstance] <Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>] [[-SqlCredential]
<Pscredential>] [[-LogNumber] <System.Int32[]>] [[-Source] <System.Object[]>] [[-Text] <String>] [[-After]
<Datetime>] [[-Before] <Datetime>] [-EnableException <Switch>] [<CommonParameters>]
DESCRIPTION
Gets the "SQL Error Log" of an instance. Returns all 10 error logs by default.
PARAMETERS
-After [<Datetime>]
Filter the results based on datetime value.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-Before [<Datetime>]
Filter the results based on datetime value.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-EnableException [<Switch>]
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.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-LogNumber [<System.Int32[]>]
An Int32 value that specifies the index number of the error log required.
Error logs are listed 0 through 99, where 0 is the current error log and 99 is potential oldest log file.
SQL Server errorlog rollover defaults to 6, but can be increased to 99. https://docs.microsoft.com/en-us/sql/da
