JOE supports heartbeat attributes for Agents

Feature

• The Agent can be configured to consider the following heartbeat settings:
  • HTTP Heartbeat Period: specifies a number of seconds after which the Agent will send a heartbeat signal to the Master if not otherwise a HTTP operation with the Master is performed.
    • Default Value: 10
  • HTTP Heartbeat Timeout: specifies a number of seconds for the latest point in time when the Agent expects to receive a heartbeat from the Master.
    • Default Value: 15
• Validation Rules for adding values with JOE
  • HTTP Heartbeat Period: > 0
  • HTTP Heartbeat Timeout: > HTTP Heartbeat Period
• Default Values
  • Default values are handled by the JobScheduler. JOE should not handle default values.
• Example

  <process_class  max_processes="10">
      <remote_schedulers>
          <remote_scheduler remote_scheduler="http://127.0.0.2:5000" 
                 http_heartbeat_period="10" 
                 http_heartbeat_timeout="15"/>
      </remote_schedulers>
  </process_class>
