Though it may do it from a remote windows based system, seems this product can test verious services.

Hi John:

Good stress-testing is non-trivial, but here's a way to (at least) create CPU, I/O and memory utilization. You can encapsulate each of the code snippets into a shell script and launch multiple invocations too.

For creating a CPU load that stops after 60-seconds:

# perl -e '$SIG{ALRM}=sub {exit};alarm 60;1 while {}'

...change the value of 'alarm 60' according to your tastes.

For allocating some memory and sleeping for some period thereafter:

# perl -e '$sz=$ARGV[0] ||1_000_000;@a=1..$sz;sleep 30'

...You may need to adjuct the default allocation of 1,000,000 characters depending upon your kernel parameters. You can pass any value you want, too:

# perl -e '$sz=$ARGV[0] ||1_000_000;@a=1..$sz;sleep 30' 50000

...means allocate a string of 50,000 characters instead of the default 1,000,000.

As for I/O, use the classic one:

# dd if=/dev/rdsk/c2t0d0 of=/dev/null bs=256k count=1000

...vary the count parameter to vary the amount of time doing I/O.

Regards!

Hi John,

beside many other tools you can use the exerciser tool from the diagnostics too.

For i/o testing, iozone works well and can produce excel files that can be graphed.
