How to check whether kibana and elsasticsearch-head services are started

the kibana and elasticsearch-head corresponding to the higher version of elasticsearch are developed by nodejs, and the startup is also started through the command npm run start of nodejs

but after startup, how to determine whether the service is started

other services can generally be judged by ps-ef | grep xxx, but the services of these two nodejs cannot be judged in this way. How to determine whether the service is started and how to shut down the service?
