hlMatrixControlAlDeletes
Module: RMON2-MIB
OID (symbolic): RMON2-MIB::hlMatrixControlAlDeletes
OID (numeric): 1.3.6.1.2.1.16.15.1.1.9
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
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.
What is hlMatrixControlAlDeletes?
This object holds a running count of application-layer flows removed from active tracking. Engineers use this alongside insert counts to understand application session churn and detect abnormal termination patterns. Comparing to inserts shows whether applications are completing cleanly or crashing.
