For Havana, alarm evaluation is based on a service at arms-length from the metering pipeline, which retrospectively polls the statistics API over the configured evaluation window with the query constraints for each alarm rule.
There has been some discussion about moving the alarm evaluation logic into the sample/event ingestion pipeline.
The purpose of this session is to gather together the stake-holders in the alarming feature and trash through the potential benefits and pit-falls of such an approach.
