Hi: 

As responded below in the list yes you can use ^MONMGR in the terminal to email out to recipients whenever you have an error above a certain alert level. 

As alexander says and we do use an external service that also reads the cconsole/messages log and texts for high alerts

Hi i'm not sure i understand what you are trying to achieve. Your current state of the mirror is Caught up in terms of journal restore. This means in the current environment your journals are currently up to date with the Primary server as per the documentation. What/Why are you trying to restore a journal as from the mirror monitoring and you are in a mirrored environment it does not look like you need to Journal restore at the moment?

Do you have any html type formatting in the traces? I have noticed this can cause issues within a visual trace before
