I am not sure what configuration I am missing here, However when I run below query in Developer console in my Developer Org, I get all events like Visualforce, ReporExport, Apex Trigger etc... but when I run same query on my production Organization, I only get Login and Logout files. Production Org is hugely customized and millions of API's are being used daily but I am not getting any log event.
Select Id, EventType, LogDate, LogFile, LogFileContentType from EventLogFile
