I created several Event Log sensors, some work via Windows API and some via WMI. When I filter for the Event Type Error and for the Event Source Backup like I see it in the Windows event viewer, the sensors just do not react to this entry when appearing in the event log. The sensors do not change at all, even though they should show the Down status.
Why do my Event Log sensors ignore error log entries and stay in the Up status? How can I make these sensor types to consider new log entries and switch to the corresponding status?
