MeasureWare Data Walkthrough:Global Memory Graph• GBL_MEM_PAGE_REQUEST_RATE• <strong>The</strong> number of page requests to or from the disk persecond during the interval. This is the same as the sum ofthe "page ins" <strong>and</strong> "page outs“ values from the "vmstat -s"comm<strong>and</strong>. Remember that "vmstat -s“ reports cumulativecounts.• Higher than normal rates can indicate either a memory ora disk bottleneck. Compare GBL_DISK_UTIL_PEAK <strong>and</strong>GBL_MEM_UTIL to determine which resource is moreconstrained. High rates may also indicate memorythrashing caused by a particular application or set ofapplications. Look for processes with high major faultrates to identify the culprits.March 2004 Copyright © 2004 <strong>HP</strong> corporate presentation. All rights reserved. 58
