hlHostControlNlDeletes
Module: RMON2-MIB
OID (symbolic): RMON2-MIB::hlHostControlNlDeletes
OID (numeric): 1.3.6.1.2.1.16.14.1.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description:
The number of times an nlHost entry has been deleted from the nlHost table (for any reason). If an entry is deleted, then inserted, and then deleted, this counter will be incremented by 2.
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 hlHostControlNlDeletes from hlHostControlNlInserts.
What is hlHostControlNlDeletes?
This running count shows how many host entries have been removed from the network-layer host table due to aging, memory limits, or probe configuration changes. Subtract it from insertions to estimate the current active unique host count. Rapid deletion rates suggest hosts are appearing and disappearing quickly, which might indicate a scan or a transient network segment.
