Notes: Ideas are e.g. better visual representation of the inventory (graphical forests), new graphing code for metrics (as DOM+CSS+JS versions), allowing different availability check interval for 'important' resources, separating agent heart beat from availability messages or combining data from different resources and types to trigger alerts on this combined data ("Correlation units"). Other ideas are very welcome. Also check the Ideas wiki page at http://rhq-project.org/display/RHQ/Ideas
