  3. Alive indicates whether the node survives.
  4. ReplayedJournalId represents the maximum metadata log ID that the node has currently replayed.
  5. LastHeartbeat is the latest heartbeat.
  6. IsHelper indicates whether the node is a helper node from BDBJE.
  7. ErrMsg is used to display error messages when the heartbeat fails.
