Defining an alert level threshold

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.

Configuration

All configuration of Remote Service is done via ossec.conf using <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>

This will set to level 6 the minimum severity level for alerts to be stored to alerts.log and/or alerts.json.

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