Every event in Hub creating, deleting, updating an account, project, service and so on is logged and stored.
To review any data update in Hub, select Audit Events from the Server Settings section of the Administration menu. On the Audit Events page, use the search box to filter the list of logged events.
You can also download information about any event as a JSON file for further investigation. To do so, select one or several events in the list and click the Download as .json button.
This operation downloads the 1000 most recent events. If the JSON download doesn't include all of the information you're looking for:
Filter the list of audit events to exclude activity that isn't relevant to your investigation.
Retrieve events in excess of the 1000 maximum using the Hub REST API.
