AlertAggregator

class AlertAggregator extends AnyRef

Aggregates alerts together and can periodically emit and log aggregated alerts. Uses memory linear in the number of (description, exception class) pairs seen between alert emissions. This is meant to make it feasible to report exceptions that may occur at very high rates.

To control memory use and noisiness of alerting, it is important to avoid using a wide variety of descriptions.
