NAME
getdelays -- Display delay statistics SYNOPSIS
getdelays -c command getdelays -p pid getdelays -t tid DESCRIPTION
The getdelays utility helps pin-point possible resource shortages when running an application. The SLES10 kernel includes patches to imple- ment delay accounting, which measures the time a process spends waiting for disk I/O, swap I/O and CPU time slices. For example, if an application is running rather slowly, delay accounting can tell you where it spends all its time. For instance, when the CPU delay is high, this means the application is competing with other proces for run time, but is losing quite often. High memory delays mean that the sum of applications running on this system need more physical memory than is available, and are swapping quite a lot. In order to enable delay accounting, you need to specify delayacct on the kernel command line when booting the system. Getdelays has three modes of operation: getdelays -c command This will invoke command and print a summary of delay statistics when the command finishes. getdelays -p pid This will print the current delay statistics of the process identified pid. getdelays -t tid This will print the current delay statistics of the thread group identified tid.
