Hi I believe you're looking for this. There is no option to control the refresh interval though. It's calculated automatically based om the dashboard's/tile's timeframe
Great question! Now within Dynatrace you cant officially rotate dashboards in the UI. What we do is we make the dashboards as we want to see them. 3 Dashboard focusing on 2 specific applications and one as an overall of the organization. We then downloaded a Chrome plugin that allows us to cycle through tabs. So we defined the tabs as the urls to the dashboards and set them so now every 15 seconds, chrome cycles through the tabs. Chrome Extensions are great and really enhance your ability to display a collection of dashboards!
