Using admintools to List Nodes for a Particular Database
Jim_Knicely
Administrator
The Vertica Administration tools allow you to easily perform administrative tasks such as quickly viewing information and statuses of all database nodes via the list_allnodes tool.
Example:
[[email protected] ~]$ admintools -t list_allnodes Node | Host | State | Version | DB -------------------------+---------------+-------+-----------------+-------------- v_port_5432_node0001 | 192.168.2.200 | DOWN | vertica-9.1.1.1 | port_5432 v_port_5435_node0001 | 192.168.2.200 | DOWN | vertica-9.1.1.1 | port_5435 v_rename_me_node0001 | 192.168.2.200 | DOWN | vertica-9.1.1.1 | rename_me v_rename_me_node0002 | 192.168.2.201 | DOWN | vertica-9.1.1.1 | rename_me v_rename_me_node0003 | 192.168.2.202 | DOWN | vertica-9.1.1.1 | rename_me v_sfdc_node0001 | 192.168.2.200 | DOWN | vertica-9.1.1.1 | sfdc v_test_4_nodes_node0001 | 192.168.2.200 | DOWN | vertica-9.1.1.1 | test_4_nodes v_test_4_nodes_node0002 | 192.168.2.201 | DOWN | vertica-9.1.1.1 | test_4_nodes v_test_4_nodes_node0003 | 192.168.2.202 | DOWN | vertica-9.1.1.1 | test_4_nodes v_test_4_nodes_node0004 | 192.168.2.203 | DOWN | unavailable | test_4_nodes v_test_db_node0001 | 192.168.2.200 | UP | vertica-9.1.1.1 | test_db v_test_db_node0002 | 192.168.2.201 | UP | vertica-9.1.1.1 | test_db v_test_db_node0003 | 192.168.2.202 | UP | vertica-9.1.1.1 | test_db
If I only want to see the IP addresses and states of the nodes from a particular database, I could combine the Linux grep and awk commands to limit the output of admintools like so:
[[email protected] ~]$ admintools -t list_allnodes | grep test_db | awk '{print $1,$3,$5}' v_test_db_node0001 192.168.2.200 UP v_test_db_node0002 192.168.2.201 UP v_test_db_node0003 192.168.2.202 UP

Is it known what the cause is that made the version 'unavailable' on the following line when it was stated in all other nodes?
v_test_4_nodes_node0004 | 192.168.2.203 | DOWN | unavailable | test_4_nodes
