# Watch 

###
Companion object Watch

#### class Watch[T] extends AnyRef

Watches are a way of specifying a view of data (e.g. list of nodes, KV pairs, health checks) which is monitored for updates. When an update is detected, an `Handler` with `AsyncResult` is invoked. As an example, you could watch the status of health checks and notify when a check is critical.
