Resource changes that are reported to Config are recorded only after the resource recorder is enabled. For details about the resource recorder, see Resource Recorder.
You can view resource changes over a time period. A record will be added to the resource timeline when the related service reports a resource attribute or relationship change to Config and the record will be retained for seven years by default.
By default, resource changes of the latest three months are displayed.
You can also click View JSON File to view the resource attributes reported to Config.
