NAME

stressapptest - stress test application for simulating high load situations

SYNOPSIS

stressapptest [options]

DESCRIPTION

This manual page documents briefly the stressapptest command.

stressapptest (unix name for Stressful Application Test) is a program that tries to maximize randomized traffic to memory from processor and I/O, with the intent of creating a realistic high load situation in order to test the existing hardware devices in a computer.

OPTIONS

This program supports the following options:
-A
Run in degraded mode on incompatible systems.
-C <threads>
Number of memory CPU stress threads to run.
-d <device>
Add a direct write disk thread with block device (or file) 'device'.
-f <filename>
Add a disk thread with tempfile 'filename'.
-F
Don't result check each transaction.
-i <threads>
Number of memory invert threads to run.
-l <logfile>
Log output to file 'logfile'.
-m <threads>
Number of memory copy threads to run.
-M <mbytes>
Megabytes of RAM to test.
-n <ipaddr>
Add a network thread connecting to system at 'ipaddr'.
-p <pagesize>
Size in bytes of memory chunks.
-s <seconds>
Number of seconds to run.
-v <level>
Verbosity (0-20), default is 8.
-W
Use more CPU-stressful memory copy.
--blocks-per-segment <number>
Number of blocks to read/write per segment per iteration (-d).
--cache-size <size>
Size of disk cache (-d).
--cc_inc_count <number>
Number of times to increment the cacheline's member.
--cc_line_count <number>
Mumber of cache line sized datastructures to allocate for the cache coherency threads to operate.
--cc_test
Do the cache coherency testing.
--destructive
Write/wipe disk partition (-d).
--filesize <size>
Size of disk IO tempfiles.
--findfiles
Find locations to do disk IO automatically.
--force_errors
Inject false errors to test error handling.
--force_errors_like_crazy
Inject a lot of false errors to test error handling.
--listen
Run threads that listen for incoming net connections.
--local_numa
Choose memory regions associated with each CPU to be tested by that CPU.
--max_errors <number>
Exit early after finding specified number of errors.
--monitor_mode
Only do ECC error polling, no stress load.
--no_errors
Run without checking for ECC or other errors.
--paddr_base <address>
Allocate memory starting from this address.
--pause_delay <seconds>
Delay (in seconds) between power spikes.
--pause_duration <seconds>
Duration (in seconds) of each pause.
--random-threads <number>
Number of random threads for each disk write thread (-d).
--read-block-size <size>
Size of block for reading (-d).
--read-threshold <time>
Maximum time (in us) a block read should take (-d).
--remote_numa <time>
Choose memory regions not associated with each CPU to be tested by that CPU.
--segment-size <size>
Size of segments to split disk into (-d).
--stop_on_errors
Stop after finding the first error.
--write-block-size <size>
Size of block for writing (-d). If not defined, the size of block for writing will be defined as the size of block for reading.
--write-threshold <time>
Maximum time (in us) a block write should take (-d).
