Healing operation counted as successful if the execution environment is deleted and recreated successfully. The scope of feature covers the NS/VNF/VDU level proxy charm healing.

• Native Charms

  osm ns-heal NS_NAME|NS_ID --cause "Heal the charm of native_manual_scale_charm_vnf" --ee-id --count-id
