It provides a measure of time delay (latency) for requests made to a system’s disk unit. The measurements are taken form the Storport.sys driver, the lowest Microsoft component in the Storage Stack.
This means It only includes the latency for the components BELOW the Storport driver, normally they only include:
- The Storage Adapter Miniport Driver (Hardware device driver)
- The hardware layers (Storage Controller, Cables, Disk, etc)
Prerequisites
- XPerf und Windows Performance Analyzer installed
Create and run storport trace
storport" -ow -o c:\temp\storport.etl -p "Microsoft-Windows-StorPort" 0xffffffffffffffff 0xff -nb 16 16 -bs 1024 -mode Circular -f bincirc -max 4096 -ets
Convert storport trace to a readable file (csv)
xperf -i mystorporttrace.ETL -o myoutputfile.csv
