    It looks to me your alerts are a mess, you can find the truth running this...
    Code:
    select  * 
    from    v$system_event 
    where   event like '%wait%'
    order by time_waited_micro DESC
    ;
    ... at least, the big picture.

    If some of my guys comes to me with that report I would say... Can't read it, would you mind in formatting the output properly?

    ... at least do
    set linesize 180
    set pagesize 999

    I do not see any issue from wait events. BTW what's your problem in D/B exactly you are facing?
