entStateLastChanged
Module: ENTITY-STATE-MIB
OID (symbolic): ENTITY-STATE-MIB::entStateLastChanged
OID (numeric): 1.3.6.1.2.1.131.1.1.1.1
Node type: OBJECT-TYPE
Type: DateAndTime
Access: read-only
Description: The value of this object is the date and time when the value of any of entStateAdmin, entStateOper, entStateUsage, entStateAlarm, or entStateStandby 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 entStateLastChanged?
This object records the date and time any of this physical entity's administrative, operational, usage, alarm, or standby states last changed. Admins use it to know how long an entity has held its current state, or to spot which component recently transitioned, e.g. going down. For example, entStateLastChanged showing a timestamp from five minutes ago alongside a disabled entStateOper would flag a component that just failed.
