recently I made some test drives with ADF Apps in Oracle Cloud. http://cloud.oracle.com
On the Monitoring side (Java Cloud Service Control > application1 > ADF Performance) I noticed that both Metrics - the Application Module Statistics and Taskflow Statistics) do not show up as expected. See my blog post for detailed information http://multikoop.blogspot.de/2012/12/managing-adf-applications-with-oracle.html
Is that a shortcoming to the trial account or a bug or some missing ADF Configuration?
