If you will not monitor a container, then add the label "monitoring=false"
If you will monitor processes in container you need to define for this a label "processes: '["apache2", "mysqld", "python","vi"]'"

in docker-compose.yml

nginx1:
  image: nginx
  hostname: proxyhosting
  ports:
   - "192.168.42.74:9295:80"
  labels:
    monitoring: "true"
    processes: '["nginx"]'
  volumes:
