GS_NODE_STAT_RESET_TIME

GS_NODE_STAT_RESET_TIME provides the statistics reset time of the current node and returns a timestamp with the time zone.

For details, see the get_node_stat_reset_time() function.

When an instance is running, its statistics keep rising. In the following cases, the statistical values in the memory will be reset to 0:
  • The instance is restarted or a cluster switchover occurs.
  • The database is deleted.
  • A reset operation is performed. For example, the statistics counter in the database is reset using the pgstat_recv_resetcounter function or the Unique SQL statements are cleared using the reset_instr_unique_sql function.

If any of the preceding events occurs, GaussDB(DWS) will record the time when the statistics are reset. You can query the time using the get_node_stat_reset_time function.
