I have a Java program. I want to measure the total memory used by the program, especially the peak memory. Is there a way to do it?

Can anyone please help me in measuring the system call timings!

ql-set-cmd-timeout(8) System Administration ql-set-cmd-timeout(8)
NAME
ql-set-cmd-timeout - set the timeout on the devices connected to the QLogic FC HBA.
SYNOPSIS
ql-set-cmd-timeout [OPTIONS]
DESCRIPTION
QLogic Linux Set Device Timeout Utility
This utility allows you to set the timeout on the devices connected to the QLogic FC HBA. This timeout value applies to the commands sent
to the device. This can help when target devices take longer to execute a command, for example under heavy I/O. Setting a longer timeout
reduces the chance of the Linux SCSI mid-layer driver aborting the tasks after a timeout.
[DEFAULT]
Display timeout of devices connected to all HOSTs
[HOST]
Display timeout of devices connected to HOST
[HOST] [TARGET]
Display timeout of devices connected to a TARGET on HOST
[HOST] [TARGET] [TIMEOUT]
To set timeout on devices connected to a TARGET on HOST
