No Data in Grafana Dashboard

[ledaf78]

I was trying this guide https://homelabing.fr/pfblockerng-and-monitoring-pfsense-with-telegraf-influxdb-and-grafana/ but the data do not appear in the dashboard is there any kind of update should I do? The no data is from pfBlocker stats which I already set like the guide, with CPU total and temperature, I was trying to fix it in Grafana query but never found it. I am trying it with pfsense VM. Can anyone help me
