total_elapsed_time | bigint | Total time elapsed since system start or restart. | Total time elapsed since system start or restart. If total_elapsed_time exceeds the maximum value for an integer (24.8 days in milliseconds), it will cause materialization failure due to overflow. The maximum value in milliseconds is equivalent to 24.8 days. |
is_available | bit | Flag indicating whether this node is available. | |
sent_time | datetime | Last time a network package was sent by this node. | |
