Liveliness QoS offers the following settings to detect failures on the publishing node:

• AUTOMATIC
  Infrastructure managed (default), leases are renewed automatically by the service. Only process failures can be detected this way.
  
• MANUAL_BY_PARTICIPANT
  Application managed, the entire Domain Participant renews its lease when one of its contained Entities asserts its liveliness, either explicitly or implicitly.
  
• MANUAL_BY_TOPIC
  Application managed, each Data Writer is responsible for renewing its own lease, either implicitly or explicitly.
