While looking how to show the stats in a dashboard for the benefit or a larger audience that the admins.. I noticed that the url plugin/cluster-stats/ 'just' works, even for anonymous users.. that is fine, except that the button 'Delete Recorded Information' is also there... that is less 'fine'...

PS: I have not checked if click the button actually delete the data.. I'm in no rush to loose it

In order of preference:

• the two button are not shown unless you are admin
• the buttons are shown but do not do anything (or error-out) if not admin
• the whole page is protected and require admin
