I have a machine that is not creating alerts.

I am not quite sure I understand the problem, would it be possible to share a screenshot?

I am unable to send a screenshot as When I try it gives me an error and does not insert into this passage, But what I am trying to say is that Rapid Recovery when doing anything should create a log in the events tab under alert. It was working previously but it randomly stopped taking alerts.

Try the following:

• Stop the core service
• Go to the folder C:\ProgramData\AppRecovery
• Rename the folder EventsDatabase to something else, for instance, EventsDatabase.old
• Start the service

This will recreate the events database file where the events and alerts are saved. 

The only downside is that you will lose the historical events.
