Hi, I'm trying to define a threshold for the alerting using the field system.diskio.iostat.await from a metricbeat running on some VMs. The documentation indicates that this field is a float with the average time spent for requests issued to the device to be served.

Can I know if this is seconds or miliseconds?

The code indicates this is in mili seconds. Could you check if that makes sense when you look at your data?

We should document this on our end.
