Hi, I would like to know whether the elasticsearch heartbeat has a specific port where it listens for incoming requests. I am running the elasticsearch heartbeat in AWS ECS. Are there any specific container ports for Heartbeat, like elasticsearch, which has ports 9200 and 9300?
Heartbeat by default doesn't run an HTTP server, it makes outbound requests only. It can run one for debugging and reporting internal stats, but that is an atypical use-case.
