I don't believe there is any setting or property for that to happen. You do have some options though:
- Create a scheduled task that runs say every 5 or 10 minutes and grabs all the events and writes them to the other database, then delete them from Kentico.
- Use the web.config key (
<add key="CMSLogEventsToFile" value="true"/>) setting to log the events to the file system and parse out the file to your other database with some other code. Believe this still logs the events to the Kentico table though.
Either option, you need to write to the Kentico table first and then manage them from that table or file. There may be a global handler you could write as well but I think the first option is the simplest and most manageable.
