ctEntStateLastChanged
Module: CTRON-ENTITY-STATE-MIB
OID (symbolic): CTRON-ENTITY-STATE-MIB::ctEntStateLastChanged
OID (numeric): 1.3.6.1.4.1.52.4.2.31.1.1.1.1.1

Description: The value of this object is the date and time when the value of any of ctEntStateAdmin, ctEntStateOper, ctEntStateUsage, ctEntStateAlarm, or ctEntStateStandby changed for this entity.
If there has been no change since the last re-initialization of the local system, this object contains the date and time of local system initialization. If there has been no change since the entity was added to the local system, this object contains the date and time of the insertion.
What is ctEntStateLastChanged?
This is a timestamp recording the last time any of this physical entity's admin, operational, usage, alarm, or standby state attributes changed. It gives an admin a quick way to spot recently changed hardware components without polling each individual state field separately. For example, seeing a timestamp from five minutes ago on a power supply entity, right after a reported outage, confirms a state transition happened at that exact moment.
