I am checking logs in cloudwatch to see who last deployed to our EB instance and when. To do this, I am filtering the API Activity History by resource name.
In the list of actions I see {Register/Deregister}InstancesWithLoadBalancer
events. Each has the name of the initiating user. Most are the names of users registered in IAM, but every so often there is a user with a system generated id in the form i-xxxxxxxx
.
"who" is this user and what is happening to cause this event?
