Prometheus + InfluxDB + grafana template variable not working while constructing the query

Dear All,
I recently installed Grafana to draw prometheus node metrics which are stored in influx DB, I am not getting the query executed successfully, Any help is appreciated. I am using template variable to list all 100 hosts in my small DC.

Did you check the response from your query? Singlestat panel queries should only return one time series. Make sure your query set returning the data you want.
