stressapptest是一款免费的开源软件，支持用于测试Linux系统的稳定性和可靠性。它可以利用多个CPU/Core，甚至可以访问主内存的所有部分来测试系统的稳定性，以此推断系统是否存在内存泄漏或其他性能方面的问题。

stressapptest的主要目标是发现难以重现的系统稳定性问题和其他体现在Java虚拟机、KVM Hypervisor和Hadoop集群等普通用例中的Linux系统中的性能问题。它还包括多个测试模式和选项以支持不同测试场景，比如随机测试、循环测试、全内存测试、持续测试等。

二、安装

2.1、源码编译安装

// 1.下载源码
git clone https://github.com/stressapptest/stressapptest.git

cd stressapptest
./configure
make
sudo make install

2.2、命令行安装

Ubuntu下执行如下命令进行安装：

sudo apt-get install stressapptest

在这里插入图片描述

2.3、安装确认

执行如下命令来确认stressapptest 是否安装成功：

stressapptest -h

–findfiles find locations to do disk IO automatically
-d device add a direct write disk thread with block device (or file) ‘device’
-f filename add a disk thread with tempfile ‘filename’
-l logfile log output to file ‘logfile’
–max_errors n exit early after finding ‘n’ errors
-v level verbosity (0-20), default is 8
-W Use more CPU-stressful memory copy
-A run in degraded mode on incompatible systems
-p pagesize size in bytes of memory chunks
–filesize size size of disk IO tempfiles
-n ipaddr add a network thread connecting to system at ‘ipaddr’
–listen run a thread to listen for and respond to network threads.
–no_errors run without checking for ECC or other errors
–force_errors inject false errors to test error handling
–force_errors_like_crazy inject a lot of false errors to test error handling
-F don’t result check each transaction
–stop_on_errors Stop after finding the first error.
–read-block-size size of block for reading (-d)
–write-block-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
–segment-size size of segments to split disk into (-d)
–cache-size size of disk cache (-d)
–blocks-per-segment number of blocks to read/write per segment per iteration (-d)
–read-threshold maximum time (in us) a block read should take (-d)
–write-threshold maximum time (in us) a block write should take (-d)
–random-threads number of random threads for each disk write thread (-d)
–destructive write/wipe disk partition (-d)
–monitor_mode only do ECC error polling, no stress load.
–cc_test do the cache coherency testing
–cc_inc_count number of times to increment the cacheline’s member
–cc_line_count number of cache line sized datastructures to allocate for the cache coherency threads to operate
–paddr_base allocate memory starting from this address
–pause_delay delay (in seconds) between power spikes
–pause_duration duration (in seconds) of each pause
–local_numa choose memory regions associated with each CPU to be tested by that CPU
–remote_numa choose memory regions not associated with each CPU to be tested by that CPU
–interleave_size bytes size in bytes of each channel’s data as interleaved between memory channels
–channel_width bits width in bits of each memory channel
–memory_channel u1,u2 defines a comma-separated list of names
for dram packages in a memory channel.
Use multiple times to define multiple channels.
