If we're submitting messages every given node with a predictable frequency, we should be able to determine that a message was lost simply by noting a gap in the timestamps. Also, if we're sending cumulative statistics then the loss of a single message (or even a fair number of them) shouldn't impact our ability to meter too much. -James _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
