Which Metric is used for Disk latency

mengsuan_koe1 — Thu, 11 Aug 2022 13:29:13 GMT

I am trying to look specific metric or calculation used by Dynatrace for Disk Latency, especially for Windows Server.

Is it 'Avg Disk sec/Read' and 'Avg Disk sec/Write'?

Within the host page (the new look), scroll to the Disk analysis part, check the metric you are looking for and click on the ... next to the chart

There you will find the magic button Show in data explorer

I am wishing to find out how does the OneAgent collect Disk Latency data from Windows server. It should be a perfmon metric I assume.

I think for Windows it should be WriteTime / WriteCount from DeviceIoControl(IOCTL_DISK_PERFORMANCE) and the same for ReadTime / ReadCount
