I don't know about a way to give you an exact number of events (maybe /Logger/Run duration). 

I personally use 
    WAIT ODBValue,"/Equipment/DTM/Statistics/Events sent",>,100

Where DTM is the frontend of my trigger. Because of the lag in the run stop, the run will always exceed by few
seconds*rates.

Hope it helps
