Interactive Reports for Databases - Exceptions 
Part of checking the overall status of a database is to consider how many errors of various categories have occurred in the database. In the context of interactive reporting, the following report gives you a quick overview of the development of these metrics over time:
Deadlocks (
<system ID> on <database host> 
Exceptions Deadlocks 
)The report shows the total number of deadlocks in the respective time periods. This is a situation in which two or more processes deadlock and each process waits for another process to release the lock.
