### Description

```asn1
hlMatrixControlAlDeletes OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of times an alMatrix entry has been
deleted from the alMatrix tables. 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 alMatrixSDTable and alMatrixDSTable 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 table size can be determined by subtracting
hlMatrixControlAlDeletes from hlMatrixControlAlInserts."
