SQL select 打印 Icinga2 主机组中的所有主机名

Question

select alias from icinga_hosts; 打印每个主机组中的所有主机名。

select alias from icinga_hostgroups; 打印所有主机组。

我看不到如何 "select select alias from icinga_hosts where icinga_hostgroups is "customer0";

换句话说，'print all the hostnames in hostgroup customer0'.

我需要某种加入吗？这是 MariaDB 5.5。感谢您的任何建议。

Answer 1

您需要 icinga_hostgroup_members table 如：

SELECT groups.alias AS 'Group',
  hosts.alias AS Host
FROM icinga_hosts AS hosts 
JOIN icinga_hostgroup_members AS group_members     
  ON hosts.host_object_id = group_members.host_object_id 
JOIN icinga_hostgroups AS groups     
  ON group_members.hostgroup_id = groups.hostgroup_id 
WHERE groups.alias = 'customer0';

Answer 2

select oh.name1 as host_name, ohg.name1 as hostgroup_name

from icinga_hosts h

join icinga_objects oh on h.host_object_id=oh.object_id

join icinga_hostgroup_members hgm on hgm.host_object_id=h.host_object_id

join icinga_hostgroups hg on hg.hostgroup_id=hgm.hostgroup_id

join icinga_objects ohg on hg.hostgroup_object_id=ohg.object_id

where ohg.name1='linux-servers';
