> If monitor aggregation is enabled we do not do collector side 5 minutes aggregation. If a monitor is down we do not get metrics from that host. Metrics collector should check that metrics from a host are available per minute but aggregates are not.
> This could be based on liveliness check of a monitor. More like a heartbeat ping. When we loose ping for > 1 min < 5 min we can aggregate metrics for that time period and hostId.
> Sinks and monitor should switch back to collector reporting state if local aggregation app is not available.
