Every posible event on the Wazuh Agent is set with certain level, by default is 1, all events from this level will trigger and alert into Wazuh Manager.
All configuration of Remote Service is done via
<alerts> XML tag, all the available options are detailed in Alerts reference
<ossec_config> <alerts> <log_alert_level>6</log_alert_level> </alerts> </ossec_config>

When you change any value on
ossec.conf file, you need to restart the service to enabling previously changed values.
