Comment 5 for bug 1061817

If the agent creates a unique sequence id (like a uuid) each time it starts, that gives us a value that is the same for all events for a given run of the agent. We can then use it to group the query results. The result for a meter would be the total of the max volumes for that meter grouped by resource id and sequence id.

This doesn't work if the agent restarts but the counter doesn't reset, though, so I'm not sure it really helps after all.
