hlHostControlNlInserts
Module: RMON2-MIB
OID (symbolic): RMON2-MIB::hlHostControlNlInserts
OID (numeric): 1.3.6.1.2.1.16.14.1.1.4
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description:
The number of times an nlHost entry has been inserted into the nlHost table. If an entry is inserted, then deleted, and then inserted, 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 hlHostControlNlInserts?
This running count increments each time a new network-layer host is discovered and added to the host statistics table. Use it to understand how many unique IP-based hosts the probe has seen. If this counter jumps suddenly, new hosts or subnets may have appeared on the monitored segment.
