hlHostControlAlDeletes
Module: RMON2-MIB
OID (symbolic): RMON2-MIB::hlHostControlAlDeletes
OID (numeric): 1.3.6.1.2.1.16.14.1.1.9
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description:
The number of times an alHost entry has been deleted from the alHost 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 hlHostControlAlDeletes from hlHostControlAlInserts.
What is hlHostControlAlDeletes?
This running count records application-layer host entries removed from the table by aging or memory pressure. Use it with insertions to estimate how many unique application instances are currently active. High delete rates suggest short-lived application instances or frequent service restarts.
