Get more info about the last errors in Oracle

Question

Hi all,
There is a log in a live system where it is possible to see every minute the following error:
Sweep Incident[48073]: failed, err=[1858]
I know that error can happen mainly when:
1. Trying to insert caracter field in a numeric column
2. Using in the wrong way the function to_date()
I need more information about that error, what can be causing the error in the system and why. Is it possible to see more information about the last errors in Oracle? For example, if a query produces an error... is it possible to see in Oracle the error and the query that caused the error?
Hope you can help me.
Thanks in advance.

Thanks Niall.
I'm not sure if I got you...
What I found is that MMON makes snapshots of the database 'health' and stores this information in the AWR. So, it seems like in the database there could be a numeric column that is storing character fields, and when MMON works, it finds that error... is that right?
I found the following information:

Is there any way I can see what MMON is doing and when is failing?
Thank you very much.
