The "rate" graphs in graphite for each EventLogging schema don't work anymore: https://graphite.wikimedia.org/

It seems like they died around May 16th: https://graphite.wikimedia.org/render/?width=586&height=308&_salt=1403100054.21&from=00%3A00_20140514&until=23%3A59_20140520&target=eventlogging.schema.NavigationTiming.rate&target=eventlogging.schema.CentralAuth.rate&target=eventlogging.schema.MediaViewer.rate

Is this a known issue? At the moment I'm doing manual calculations with the database to see how much I've been able to reduce Media Viewer's usage of EventLogging, if those graphs worked it would be a lot faster to get the results.
