With the current release (2.5.0), it is not possible to add more than one event broker module on the monarch configuration(due to the primary key of setup table).
It is very important for me to have the possibility to define multiple directives. Could-you add this feature on your next release ?
Event Broker Modules
Format: broker_module=<modulepath> [moduleargs]
Example: broker_module=/usr/local/nagios/bin/ndomod.o cfg_file=/usr/local/nagios/etc/ndomod.cfg
This directive is used to specify an event broker module that should by loaded by Nagios at startup. Use multiple directives if you want to load more than one module. Arguments that should be passed to the module at startup are seperated from the module path by a space.
