stressapptest - stress test application for simulating high load situations stressapptest [ options ] 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.

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> Number of cache line sized datastructures to allocate for the cache coherency threads to operate.

--cc_line_size <number> Size of cache line to use as the basis for cache coherency test data structures.

--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).
