Description: The number of times a dsmonMatrix entry has been deleted from the dsmonMatrix tables (for any reason). If an entry is deleted, then inserted, and then deleted, this counter will be incremented by 2. The deletion of a conversation from both the dsmonMatrixSDTable and dsmonMatrixDSTable shall be counted as two deletions (even though every deletion from one table must be accompanied by a deletion from the other).

To allow for efficient implementation strategies, agents MAY delay updating this object for short periods of time. For example, an implementation strategy may allow internal data structures to differ from those visible via SNMP for short periods of time. This counter may reflect the internal data structures for those short periods of time.

Note that the sum of the dsmonMatrixSDTable and dsmonMatrixDSTable sizes can be determined by subtracting dsmonMatrixCtlDeletes from dsmonMatrixCtlInserts.
