title: Direct DB Setup on Zabbix Data Source in Grafana
body: <p>I have added Zabbix and DirectDB (MySQL) as data source in Grafana. I also enabled DirectDB in Zabbix data source configuration. I want Grafana to connect to the database that I defined in DirectDB option. I also set the Zabbix PHP endpoint in Zabbix data source configuration. I am trying to understand if the Grafana reaches to the Direct DB database through Zabbix PHP frontend or natively. If yes, is there a method to prove it?</p>
  <p>Grafana Version: v8.0.3
  Operating System: Ubuntu 20.04.2 LTS</p>
