>
> Heron has a dedicated metrics collection process per host/topology. In our
> current setup metrics collection is not always consistent, especially on
> systems and bolts that are overloaded. We should explore if the benefits of
> collecting the metrics differently and decide if there is a better way to do
> it. Especially after STORM-885, we could potentially use it as a starting
> point for this process and have it pre-aggregate the metrics/heartbeats that
> are sent to nimbus for scheduling purposes, while forwarding on other metrics
> to different systems for alerting and monitoring.
