Get-Event

Get-Event [-EventIdentifier*] <Int32> [<CommonParameters>]

Get-Event [[-SourceIdentifier] <String>] [<CommonParameters>]

The Get-Event cmdlet gets events in the Windows PowerShell event queue for the current session. You can get all events or use the EventIdentifier or SourceIdentifier parameter to specify the events.

When an event occurs, it is added to the event queue. The event queue includes events for which you have registered, events created by using the New-Event cmdlet, and the event that is raised when Windows PowerShell exits. You can use Get-Event or Wait-Event to get the events.

This cmdlet does not get events from the Event Viewer logs. To get those events, use Get-WinEvent or Get-EventLog.

Parameters

-EventIdentifier <Int32>

This value is required
Default value is None
Accepts pipeline input ByPropertyName

Specifies the event identifiers for which this cmdlet gets events.

-SourceIdentifier <String>

Default value is None
Accepts pipeline input ByPropertyName

Specifies source identifiers for which this cmdlet gets events. The default is all events in the event queue. Wildcards are not permitted.

<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,ErrorAction, ErrorVariable, WarningAction, WarningVariable,OutBuffer, PipelineVariable, and OutVariable.

Inputs

None

You cannot pipe input to this cmdlet.

Outputs

System.Management.Automation.PSEventArgs

Get-Event returns a PSEventArgs object for each event. To see a description of this object, type `Get-Help Get-Event -Full` and see the Notes section of the help topic.

Examples

Get all events:
```
PS C:\> Get-Event
```
This command gets all events in the event queue.
Get events by source identifier:
```
PS C:\> Get-Event -SourceIdentifier "PowerShell.ProcessCreated"
```
This command gets events in which the value of the SourceIdentifier property is PowerShell.ProcessCreated.

Get an event based on the time it was generated:

PS C:\> $Events = Get-Event
PS C:\> $Events[0] | Format-List -Property *
ComputerName     : RunspaceId       : c2153740-256d-46c0-a57c-b805917d1b7b
EventIdentifier  : 1
Sender           : System.Management.ManagementEventWatcher
SourceEventArgs  : System.Management.EventArrivedEventArgs
SourceArgs       : {System.Management.ManagementEventWatcher, System.Management.EventArrivedEventArgs}
SourceIdentifier : ProcessStarted
TimeGenerated    : 11/13/2008 12:09:32 PM
MessageData      : PS C:\> Get-Event | Where {$_.TimeGenerated -ge "11/13/2008 12:15:00 PM"}
ComputerName     : RunspaceId       : c2153740-256d-46c0-a57c-b8059325d1a0
EventIdentifier  : 1
Sender           : System.Management.ManagementEventWatcher
SourceEventArgs  : System.Management.EventArrivedEventArgs
SourceArgs       : {System.Management.ManagementEventWatcher, System.Management.EventArrivedEventArgs}
SourceIdentifier : ProcessStarted
TimeGenerated    : 11/13/2008 12:15:00 PM
MessageData      :

This example shows how to get events by using properties other than SourceIdentifier.

The first command gets all events in the event queue and saves them in the $Events variable.

The second command uses array notation to get the first (0-index) event in the array in the $Events variable. The command uses a pipeline operator (|) to send the event to the Format-List command, which displays all properties of the event in a list. This allows you to examine the properties of the event object.

The third command shows how to use the Where-Object cmdlet to get an event based on the time that it was generated.

Get an event by its identifier:
```
PS C:\> Get-Event -EventIdentifier 2
```
This command gets the event with an event identifier of 2.

Additional Notes

* Events, event subscriptions, and the event queue exist only in the current session. If you close the current
session, the event queue is discarded and the event subscription is canceled.

The Get-Event cmdlet returns a PSEventArgs object ( System.Management.Automation.PSEventArgs ) with the
following properties:

- ComputerName. The name of the computer on which the event occurred. This property value is populated only
when the event is forwarded from a remote computer.

- RunspaceId. A GUID that uniquely identifies the session in which the event occurred. This property value is
populated only when the event is forwarded from a remote computer.

- EventIdentifier. An integer (Int32) that uniquely identifies the event notification in the current session.

- Sender. The object that generated the event. In the value of the Action parameter, the $Sender automatic
variable contains the sender object.

- SourceEventArgs. The first parameter that derives from EventArgs, if it exists. For example, in a timer
elapsed event in which the signature has the form Object sender, Timers.ElapsedEventArgs e, the
SourceEventArgs property would contain the Timers.ElapsedEventArgs. In the value of the Action parameter, the
$EventArgs automatic variable contains this value.

- SourceArgs. All parameters of the original event signature. For a standard event signature, $Args[0]
represents the sender, and $Args[1] represents the SourceEventArgs. In the value of the Action parameter, the
$Args automatic variable contains this value.

- SourceIdentifier. A string that identifies the event subscription. In the value of the Action parameter, the
SourceIdentifier property of the $Event automatic variable contains this value.

- TimeGenerated. A DateTime object that represents the time at which the event was generated. In the value of
the Action parameter, the TimeGenerated property of the $Event automatic variable contains this value.

--MessageData. Data associated with the event subscription. Users specify this data when they register an
event. In the value of the Action parameter, the MessageData property of the $Event automatic variable
contains this value.
