Comprised of both Disk Reads/sec and Disk Writes/sec, the Disk Transfers Per Second alert provides the rate of transfer operations on the disk and helps to determine if a drive does not have enough supporting disks. Note that this alert is disk specific.

A large increase in disk transfers per second may signal a change in workload or a developing I/O or memory pressure issue.

This alert is raised based on the diagnostic data collection interval specified in Server Properties. Note that you need to enable this alert first in the Alert Configuration window to rise.

For additional information on the Disk Transfers/sec counter, see Monitoring Disk Usage.
