Question:
I created a snapshot lifecycle policy and it reached “DLM Policy State Change” state = Error.
I cannot find where to read the event with error details (cause of the failure).
I have tried cloudwatch and created a Rule, it triggered the rule but still no event details.
Answer:
I am having the same problem, my data lifecycle manager throws an Error, and I have no idea how to get it.
What I did:
Go to your CloudTrail Event History and filter by Username DataLifecycleManager.
Depending on your region, the URL should be something like:
Then you will see a list of all the DataLifecycleManager events.
The ones interesting are Event name CreateSnapshot for Resource Type EC2 Volume.
Open one and click the button “View event”.
Just for the record, I was having an error:
“Duplicate tag key ‘Name’ specified.”
