Overview
This section lists parameters supported in the PostgreSQL Zabbix agent 2 plugin configuration file (postgresql.conf).
Since Zabbix 6.0.10, PostgreSQL is a loadable plugin, which is available and fully described in the PostgreSQL plugin repository
Note that:
- The default values reflect process defaults, not the values in the shipped configuration files;
- Zabbix supports configuration files only in UTF-8 encoding without BOM;
- Comments starting with "#" are only supported at the beginning of the line.
