This message informs you that historical data in APM tables have not been summarized for some time. This indicates that Database Maintenance probably wasn't executed for several days or Database Maintenance is failing for some reason.

Please try to run is manually as Roger suggested and if message still won't away, try to contact support so we could investigate Database Maintenance log file.
