For example, if there are 3 events A, B and C which could lead to a power down fault, and B and C are caused by A. Without Holmes, all of these 3 events will be sent to Policy and 3 corresponding action are going to be triggered. After we add Holmes to the close loop controller and make it the upstream system of Policy, only Event A will be sent to Policy and thus only one action will be triggered, which makes the close loop control more precise and efficient.

TSC Comment Clarification
(Roberto Kung)
Holmes should be looked with Clamp or/and Policy, mainly policy (with introduction of engines and so on). May be a split is needed (analytics – alarm aggregation, filtering, correlation in DCAE analytics microservices / policy design RCA in policy). May not be high priority for R1 (not needed for our use cases). But it is useful to show intents for following releases
(Lingli Deng)
Just to clarify, cross-layer fault correlation is in scope for VoLTE usecase for auto-healing.
(Mazin Gilbert)
This project should be split and combine with DCAE (for the correlation engine), Policy engine (for Drools), and CLAMP (for designing the open loop).
(Lingli Deng)
What about the portal demonstrating the alarms gathered, and correleation made? Would DCAE be providing a portal for that?

What’s the relationship between CLAMP and Holmes?
(Guangrong Fu)
Holmes is essential for control loops so it should be somewhat provisioned by CLAMP. For instance, if possible, rules of Holmes can be deployed/un-deployed via CLAMP. But how to implement this is still a mystery because so far we haven't got any seed code or API docs about CLAMP, which prevents us from further analysis.
