DCGM_FI_DEV_GPU_UTIL metric giving empty value from prometheus

[Vijaygawate]

I have deployed GPU operator on EKS cluster using helm chart, also I have deployed prometheus, but when I am querying GPu utilization metric DCGM_FI_DEV_GPU_UTIL it is returning empty even when I have 27% GPU utilization

curl localhost:9090/api/v1/query?query=DCGM_FI_DEV_GPU_UTIL

output: {"status":"success","data":{"resultType":"vector","result":[]}}
