AWS Health Events Eventsource

Just checking bases: when looking at the eventsource, go up to "More" and click "Show associated devices". You should be able to click from there into one of your AWS accounts. Technically, when you add an AWS account, there is a group that contains the AWS resources. However, account level stats cannot be associated with a group. Instead, a faux resource is created in that group that represents the account level stats, including this one. When you go the more > show associated devices route, it takes you directly to the resource where the eventsource should live. You should see it the second one down (YMMV). The data tab should show entries.

If that still doesn't work, I'd recommend reaching out to Support.
