I am a beginner and I want to visualize Zabbix monitoring data in Grafana. Currently, I have set up three variables: $groups, which can get all the groups in Zabbix; $hosts, which can get all the host names under a group; and $items, which I want to get all the items on a host. However, I cannot get the items no matter how I set it up. I really hope to get some help. I have attached some screenshot of the results below.
