I am trying to find average queue length of the requests that were issued to the device. But system.diskio.iostat.queue.avg_size information is not showing in window os. I am also using Grafana to show them graphically.
Metricbeat version:7.4.1
elasticsearch version:6.4

see in the image system.diskio.iostat is not showing. Only what I am getting is read,write and io.
Can anyone help me to get iostat.
