Important: if the database location is not localhost, you will have to install postgresql on the correct host before running this role. You will need the following variables in the database host:
pg_users:
- name: zabbix
password: auto
attrib: LOGIN
pg_databases:
- name: zabbix
owner: zabbix
conn_limit: 100
extension_list:
- name: timescaledb
version: 2.19.3
pg_shared_preload_libraries:
- timescaledb
The version of timescaledb in particular is very important: the version is marked for hold to avoid any update. It must be specified with the complete version (X.Y.Z).

This role overrides the default values about the communication between a zabbix server and a passive zabbix proxy. By default, the server update the configuration on passive proxies only every hours, which is not convenient. It also query the proxy every single seconds. This role changes those value to 15 minutes and 5 seconds, respectively. You can modify those value by changing those variables:
zabbix_server_ProxyConfigFrequency: "900"
zabbix_server_ProxyDataFrequency: "5"
Those settings have no effect on active proxies.
