None of those methods worked for me. What worked was making just one of the services as essential (only the one you are sure is going to work), and then looking at Cloudwatch logs, and eventually even the ECS logs within the EC2 instance.

# ecs-params.yml

version: 1
task_definition:
  services:
    myservice1:
       essential: true
    myservice2:
       essential: false
    myservice3:
       essential: false
    myservice4:
       essential: false
    myservice5:
       essential: false

ECS's black box is not very friendly after all.
