0 - 1 of 1 tags for access counts

In our TD system the ObjectUseCountCollectRate values is set to 10(default value in 14.10), but the DBC.Objectusage table is not updated. the table is empty.
The lastaccesstimestamp and access counts has only NULL vaules in DBC.tables.
Please help me to resolve the issue. The lastaccesstimestamp would help me to a great extent.
