akka Supervision and Monitoring in Akka What is Monitoring?
Example
Lifecycle Monitoring in Akka is usually referred to as DeathWatch.
Monitoring is thus used to tie one actor to another so that it may react to the other actor’s termination, in contrast to supervision which reacts to failure.
Monitoring
Monitoring is particularly useful if a supervisor cannot simply restart its children and has to terminate them, e.g. in case of errors during actor initialization. In that case it should monitor those children and re-create them or schedule itself to retry this at a later time.
