You can configure Splunk Enterprise to monitor non-default Windows event logs. Before you can do this, you must import them to the Windows Event Viewer. Once the logs are imported, you can add them to your local copy of inputs.conf
To monitor Task Scheduler in Microsoft>Windows>TaskScheduler>Operational, right click on Operational and select properties. Use the "Full Name" to append to WinEventLog:// stanza.

[WinEventLog://Microsoft-Windows-TaskScheduler/Operational]
disabled = 0
index = wineventlog
renderXml = false
start_from = oldest
checkpointInterval = 5
