After upgrade to 12010, report exchange Messages Delivered/sec not define value per hours

Hi,

I had problem after upgrade version to 12010, I always used report exchange Messages Delivered/sec. before upgrade the report seem normal for me, its define value each per hours. but after upgrade, the report Messages Delivered/sec not given normal value as before upgrade. its not define value each per hour but only time 1.00 clock every days report.
its there any new setting for exchange monitor.
