Display Node Start Times Jim KnicelyApril 13, 2022 The pg_postmaster_start_time() function returns the start time of the server where you execute it. Example: But your YugabyteDB database is most likely a cluster of more than one node. To get the start time of each of your nodes, you can do something like this in YSQL: yugabyte=# SELECT host FROM yb_servers() ORDER BY host; -- IP address for each cluster node host ---------------- 192.168.56.110 192.168.56.111 192.168.56.112 (3 rows) yugabyte=# \! ysqlsh -h 192.168.56.110 -Atc "SELECT '\! ysqlsh -h ' || host || ' -Atc \"SELECT ''Host: ' || host || ' Start time: '' || pg_postmaster_start_time();\"' FROM yb_servers() ORDER BY host;" | ysqlsh -h 192.168.56.110 Host: 192.168.56.110 Start time: 2022-04-13 14:10:09.411879+00 Host: 192.168.56.111 Start time: 2022-04-13 14:10:48.193883+00 Host: 192.168.56.112 Start time: 2022-04-13 14:11:04.496599+0 yugabyte=# SELECT inet_server_addr(); -- IP address of current node inet_server_addr ------------------ 192.168.56.110 (1 row) yugabyte=# SELECT pg_postmaster_start_time() node_start_time; node_start_time ------------------------------- 2022-04-13 14:10:09.411879+00 (1 row) Have Fun!
