Module: HP-ENTITY-MIB
OID (symbolic): HP-ENTITY-MIB::hpEntLastChangeTime

Description: The value of sysUpTime at the time any of these events occur: * a conceptual row is created or deleted in any of these tables: - hpEntPhysicalTable - hpEntLogicalTable - hpEntLPMappingTable - hpEntAliasMappingTable - hpEntPhysicalContainsTable
* any instance in the following list of objects changes value: - hpEntPhysicalDescr - hpEntPhysicalVendorType - hpEntPhysicalContainedIn - hpEntPhysicalClass - hpEntPhysicalParentRelPos - hpEntPhysicalName - hpEntLogicalDescr - hpEntLogicalType - hpEntLogicalCommunity - hpEntLogicalTAddress - hpEntLogicalTDomain - hpEntAliasMappingIdentifier
What is hpEntLastChangeTime?
This reports the sysUpTime value at the moment any row was added or removed in the physical, logical, LP-mapping, alias-mapping, or containment tables, or any of several key physical or logical object instances changed. Admins poll this single timestamp to quickly detect whether the device's physical or logical inventory has changed at all, without having to walk every entity table on every poll. A jump in hpEntLastChangeTime since the last poll tells an admin it's worth re-walking the entity tables to pick up hardware or logical-entity changes.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11.2.14.9.1.4.1 snmpwalk -v2c -c public <target> HP-ENTITY-MIB::hpEntLastChangeTime
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11.2.14.9.1.4.1.1 snmpget -v2c -c public <target> HP-ENTITY-MIB::hpEntLastChangeTime.1
