Grafana not displaying nodename instead of IP

Grafana Configuration
1

Edited the variable section in grafana and replace the

label_values(node_load1, instance) with

label_values(nodename).

just because i have 50 servers and i wanted to see the name of the server instead of IP

But values(data) were not loading for that host. Reports as no data

any help is appreciated

Can you show your prometheus query and your raw prometheus data? What is the query sent to prometheus and the response from prometheus
