  • What are you trying to achieve?
    => Monitoring with Zabbix-Grafana

  • How are you trying to achieve it?
    => I successfully connected through the information on the Internet.

  • What happened?
    => Almost all information was displayed in Grafana immediately upon connection, but some information (Number of CPU etc.) is displayed after about an hour. It will appear as “No Data” until it is properly displayed.
    I want to know why this problem occurs.
