5 Modbus plugin
Overview
The configuration file of Zabbix agent 2 is used to configure plugins. These Zabbix agent 2 configuration parameters are supported for operating the Modbus plugin.
It is recommended to specify them in their own configuration file (e.g. modbus.conf) and then use the Include directive for adding this file to the Zabbix agent 2 configuration.
Note that:
- The default values reflect process defaults, not the values in the shipped configuration files;
- Values support environment variables;
- Zabbix supports configuration files only in UTF-8 encoding without BOM;
- Comments starting with "#" are only supported at the beginning of the line.
