Some devices have multiple event sources installed that are supported by enVision. For example, there could be checkpoint events coming from a Management Station running on a Windows device also creating windows events.

To collect multiple event types from a single device, first configure enVision and the device for one type of event collection. After the device has been discovered and set to active, go to Overview -> System Configuration -> Devices -> Manage Monitored Devices. Click on the device you just configured. Check the multi-device box. Now, configure enVision and the device for another type of event collection. This should resolve the issue.
