How to find IO Wait by Device wise?

Hi Everyone,

can you please help me to identify the IO Wait by device wise?

From the below query, I can get the percentage of iowait time for all the devices like wise I need the IO wait time for separate devices

avg(rate(node_cpu_seconds_total{node_name=~"$node_name",mode="iowait"}[5s])) * 100

output :

1.45 % (for total devices)

Expected Output :

xvda - 1.34
xvdb - 2.45
