New-PefProcessTrigger

Creates a trigger that signals when a process exits.

Sintassi

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

Descrizione dettagliata

The New-PefProcessTrigger cmdlet creates a trigger that signals when a process exits. You can use this process trigger to invoke a process at the time you start a Protocol Engineering Framework (PEF) Trace Session with the Start-PefTraceSession cmdlet. The trigger executes the process when it becomes associated with a PEF action. When the process exits, the trigger signals. The trigger becomes active when you associate it to a PEF action.

Esempi

Example 1: Create a trigger that invokes a process

This example adds a trigger to a linear PEF Trace Session that invokes the ping.exe process when the Start-PefTraceSession cmdlet runs. The session actually starts when the ping command completes.

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

The second command uses the Add-PefMessageSource cmdlet to add a provider for the Trace Session stored in the $TraceSession01 variable.

The third command uses the Stop-PefTraceSession cmdlet to stop the Trace Session stored in the $TraceSession01 variable ten minutes after the session starts, by using the New-PefDateTimeTrigger cmdlet.

The fourth command uses the Start-PefTraceSession cmdlet to start the Trace Session stored in the $TraceSession01 variable. The invoked process in the example is Ping.exe, which pings a location specified by the Arguments parameter. The sessions starts when the invoked process stops. Note that the 4 parameter value forces the use of IPv4; if unspecified, the default IP transport is used.

PS C:\> $TraceSession01 = New-PefTraceSession -Mode Linear -Name ".\myTrace.matu" -SaveOnStop -Path "C:\Traces\result.matu" -Force
PS C:\> Add-PefMessageSource -PEFSession $TraceSession01 -Source "Microsoft-Pef-WFP-MessageProvider"
PS C:\> Stop-PefTraceSession -PEFSession $TraceSession01 -Trigger (New-PefDateTimeTrigger ($dt=Get-Date).AddMinutes(10))
PS C:\> Start-PefTraceSession -PEFSession $TraceSession01 -Trigger (New-PefProcessTrigger -FilePath C:\Windows\system32\PING.EXE -Arguments "www.contoso.com -4")
