NAME Clear-DbaLatchStatistics
SYNOPSIS
Clears Latch Statistics
SYNTAX
Clear-DbaLatchStatistics [-SqlInstance] <Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>
[[-SqlCredential] <Pscredential>] [-EnableException <Switch>] [<CommonParameters>]
DESCRIPTION
Reset the aggregated statistics - basically just executes DBCC SQLPERF (N'sys.dm_os_latch_stats', CLEAR)
PARAMETERS
-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
-SqlCredential [<Pscredential>]
Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory -
Integrated are all supported.
For MFA support, please use Connect-DbaInstance.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-SqlInstance [<Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>]
Allows you to specify a comma separated list of servers to query.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
