hlMatrixControlNlDeletes
Module: RMON2-MIB
OID (symbolic): RMON2-MIB::hlMatrixControlNlDeletes
OID (numeric): 1.3.6.1.2.1.16.15.1.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of times an nlMatrix entry has been deleted from the nlMatrix 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 nlMatrixSDTable and nlMatrixDSTable 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 hlMatrixControlNlDeletes from hlMatrixControlNlInserts.
What is hlMatrixControlNlDeletes?
This object holds a running count of network-layer traffic flows that have been removed from active tracking. Engineers use this to understand session lifespans and detect whether flows are completing normally or being forcibly terminated. Unexpectedly high delete rates may indicate connection problems or aggressive timeout settings.
