New-PefTimeSpanTrigger

New-PefTimeSpanTrigger

Creates a trigger that signals after the specified time span.

Syntax

Parameter Set: Default
New-PefTimeSpanTrigger [-TimeSpan] <TimeSpan> [-InformationAction <System.Management.Automation.ActionPreference> {SilentlyContinue | Stop | Continue | Inquire | Ignore | Suspend} ] [-InformationVariable <System.String> ] [-Repeat] [ <CommonParameters>]

Detaillierte Beschreibung

The New-PefTimeSpanTrigger cmdlet creates a trigger that signals after a specified time span. You can use a timer trigger to start or stop a Protocol Engineering Framework (PEF) Trace Session after a specified time interval elapses. The trigger becomes active when you associate it to a PEF action.

Parameter

-InformationAction<System.Management.Automation.ActionPreference>

Specifies how this cmdlet responds to an information event. Die folgenden Werte für diesen Parameter sind zulässig:

-- SilentlyContinue
-- Stop
-- Continue
-- Inquire
-- Ignore
-- Suspend

-InformationVariable<System.String>

Specifies a variable in which to store an information event message.

-Repeat

Indicates that the trigger runs on each occurrence of a time-span interval that you specify. If you do not specify this parameter, the trigger runs only once.

-TimeSpan<TimeSpan>

Specifies the amount of time before the server fires the trigger.

<CommonParameters>

Dieses Cmdlet unterstützt die allgemeinen Parameter: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, -OutVariable. Weitere Informationen finden Sie unter about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Eingaben

Der Eingabetyp ist der Typ der Objekte, die über die Pipeline an das Cmdlet übergeben werden können.

Ausgaben

Der Ausgabetyp ist der Typ der Objekte, die vom Cmdlet ausgegeben werden.

Beispiele

Example 1: Add a Trace Filter by using a time span trigger

This example adds a Trace Filter to a Trace Session after a period of 150 seconds expires.

The first command uses the New-PefTraceSession cmdlet to create a PEF Trace Session object and stores it in the $TraceSession01 variable.

The second command uses the current cmdlet to create a trigger with a TimeSpan value of 150 seconds. The command stores the trigger in the $Trigger01 variable. To specify the TimeSpan value, type Get-Help New-TimeSpan to learn how to use the New-TimeSpan cmdlet.

The third command uses the Set-PefTraceFilter to set a Trace Filter with the string value "icmp" for the Trace Session object that is stored in the $TraceSession01 variable. This command specifies the trigger stored in the $Trigger01 variable, which causes the specified Trace Filter to be applied to the Trace Session message retrieval action 150 seconds after the session starts.

The fourth command uses the Add-PefMessageSource cmdlet to specify a message provider for the Trace Session object stored in the $TraceSession01 variable.

The final command uses the Start-PefTraceSession cmdlet to start the Trace Session stored in the $TraceSession01 variable.

PS C:\> $TraceSession01 = New-PefTraceSession -Mode Circular
PS C:\> $Trigger01 = New-PefTimeSpanTrigger -TimeSpan (New-TimeSpan -Seconds 150)
PS C:\> Set-PefTraceFilter -PEFSession $TraceSession01 -Filter "icmp" -Trigger $Trigger01
PS C:\> Add-PefMessageSource -Session $TraceSession01 –Source "Microsoft-Pef-WFP-MessageProvider"
PS C:\> Start-PefTraceSession –PEFSession $TraceSession01
