Which channel represents 'average response time' on the disk I/O sensor?




I have a question about WINDOWS PHYSICAL DISK I/O SENSOR.

When I look into the disk performance tab in Windows Task Manager, there is an value called Average Response Time.

I want to check the value on a Disk I/O sensor. A Disk I/O sensor have channels related response time(like Avg Read Time, Avg Transfer Time, Avg Write Time).

Which one represents 'average response time' on the disk I/O sensor?

Hello Jonathan,

Thank you for your post.

The "Average Response Time" is calculated by adding the "Average Read" and "Average Write" time, and dividing it by two. The "Windows Physical Disk I/O Sensor", does not calculate this the "Average Response Time", but rather displays the "Average Read" and "Average Write" time separately.

You could get this value by using a Sensor Factory sensor, in which you can calculate the "Average Response Time" by using the values from the Read and Write channels.

Kind regards,

Thanks for reply.

I have one more question about Disk I/O Sensor.

What does 'Avg Transfer Time' mean? How is the value calculated?

The "Avg Transfer Time" should be the average number of bytes transferred to or from the disk during write or read operations. This value is not calculated by the sensor, but is taken directly from Windows.
