1) I can't get metric data to stay in the system for more than about 8 hours.  The documentation says data retention units are in days.  I've tried using the REST APIs to set the retentions to 365 when I create a Metrics tenant.  I've also tried setting it to 365 for individual Metric definitions.  Neither approach seems to make a difference.  Am I missing something?  I'm running on Windows 7 x64.
