The script calls SWbemEventSource.NextEvent to obtain and process each event as it arrives. For more information, see Calling a Method. See the next script for an example of setting up an asynchronous temporary event subscription by calling SWbemServices.ExecNotificationQueryAsync. This script calls SWbemServices.ExecNotificationQuery, which is the semisynchronous version of the method. The script stops after five processes have started or stopped. You can see output from the script by starting Notepad.exe or any other process. To execute the script, copy it to a file named event.vbs and use the following command line: cscript event.vbs. An instance of this class is generated when a process is started or stopped. The following VBScript code example requests notification when an instance of Win32_ProcessTrace is created. Temporary event queries usually use either IWbemServices::ExecNotificationQuery in C++ applications or SWbemServices.ExecNotificationQuery in scripts and Visual Basic.Īn event query requests instances of an event class that specifies a certain type of event, such as Win32_ProcessTrace or RegistryKe圜hangeEvent. Temporary event consumers are scripts or applications that return the events that match an event query or filter. The following sections are discussed in this topic: ![]() For more information, see Monitoring and Responding to Events with Standard Consumers. WMI also supplies a set of preinstalled permanent event providers and the permanent consumer classes that enable you to permanently monitor events. You can create event monitoring scripts or applications that temporarily monitor when events occur. For more information, see Receiving a WMI Event.Įvent consumers are applications or scripts that request notification of events, and then perform tasks when specific events occur. WMI supports event detection and delivery to event consumers because some WMI providers are event providers. ![]() Security events are reported to an NT Event Log.System administrators can use WMI to monitor events on a network.
