The Disk I/O Extended Rate workspace provides detailed input/output statistics and "calculations", including the queue length and size in sectors of read and write requests, the rate of those requests, and wait times associated with requests. This workspace is comprised of two views. The views are:
Disk I/O Extended Rate (table view)
Disk I/O Rate (bar chart)
The Disk I/O Extended Rate table details the input/out data and calculated values associated with disk activity. The Disk I/O Rate chart provides "at a glance" rate details associated with disk reads, writes, and transfers. Based on the information that this workspace provides, you can recommend changes, set up situations, and verify that your recommended changes improve performance.
Note: The attributes associated with this workspace are only available for systems with a 2.4 (or higher) kernel.
