Stack usage of an application

Dear Team,
I would like find a maximum stack usage of an application. Kindly let me know how it is possible. I hope are there are some standard tool/solution available for it. Please reply me back.
Thanking you,
T.Senthil Nathan

you do so with the ulimit command
see the bash man page

Dear Mr.taxtropel & Linux users
I just saw the man page of ulimit with stack usages, it is just displaying the maximum allowable limit for an application. Sorry my question is, how do you find, how much stack is used/utilized by an application with in the given limit. Kindly reply me back.
Thanking you,
T.Senthil Nathan.

reply, oh, that's easy...first you need to find the programs PID
(process ID)

do that with ps

Code:

ps -A

will give you the PID for ALL process running on the entire system

next go to the /proc folder

Code:

cd /proc

then enter the folder which matches the PID

Code:

cd 17109

then view the status file for that process

Code:

cat status

it will look something like this...

Code:

Name:  X

State:  S (sleeping)

SleepAVG:      98%

Tgid:  17109

Pid:    17109

PPid:  17107

the stack is listed as "VmStk"

hope this helps

Ok, is it a peak usage of stack or the current utilization of stack ?. Any way I would like to know the peak utilization of stack. It would be better, if it displays in terms of byte level granularity.
Thanking you,

Dear Mr.taxtropel & Linux users,
Basically I would like to plot a graph which contains time in X-Axis and Stack usage in Y-Axis over the time. Please let me know how you can track the stack usage for an application over the time, the application may run only for few milliseconds. Kindly reply me back ASAP.
Thanking you,
T.Senthil Nathan.
