Display section controls the display of monitoring elements.
date_format : display date format for the monitoring events and monitoring loggers.
Must follow the Java date formatting rules.
clean_duplicate_events : indicates if the duplicate events generated by distinct rules must be removed.
If active, it means that several rules of same nature have been defined and are generating therefore duplicate events.
It would be preferable to review the rules, which is not always possible when handling various rule sets.
Note that, within one rule, the threshold management is always preventing such event duplication.
