Since upgrading to DNN 8 I've noticed that the Admin -> Event Viewer is missing several pieces of information that used to be present on every error. The Message, InnerMessage, and InnerStackTrace are there, but not the StackTrace, UserAgent, Referrer, RawUrl, TabId, UserId, PortalId, AssemblyVersion, FileName, FileLineNumber, FileColumnNumber, or Method. 

I looked in the EventLog table in the database and the LogProperties column only has the DefaultDataProvider, ExceptionGUID, and AbsoluteURL (even though the AbsoluteURL isn't displayed in the Event Viewer module on the site).

The ExceptionEvents table is empty. Please let me know what I need to do to get error logging working again.

Thank you.

I looked at vw_eventlog and nearly every column is empty. I've tried re-copying the install package onto the installation and still have the same issue. If there was an upgrade issue can you suggest what library or module I'd need to focus on to fix this?

I guess I misspoke. I did use the upgrade package (making sure to unblock the zip package), and the upgrade wizard indicated that it was successful. Then I noticed these problems with the event viewer. After you replied that there might have been an error in the upgrade I copied over the files from the install package to make sure no dlls or other necessary files were missing, but nothing changed. The event log is missing the information I mentioned in my original post on 3 different instances (one development and two production).
