WinCollect does not support events that are logged to a Microsoft SQL Server.
Microsoft IAS Directory Structure for Event Collection
The event logs that are monitored by WinCollect are defined by the root directory that you should configure in your log source.
When you specify a root log directory, you must point the WinCollect agent to the folder that contains your Microsoft IAS or NPS events. The root log directory does not recursively search sub-directories for event files.
To improve performance, you can create a sub folder for your IAS and NPS event logs, for example, \WINDOWS\System32\Logfiles\NPS. When you create a specific event folder, the agent does not have to evaluate many files to locate your event logs.
If your system generates a large number of IAS or NPS events, you can configure your Windows system to create a new event log at daily intervals. This action ensures that agents do not have to search large logs for new events.
