openkk 8年前

stress 是Unix类系统下的工作量和压力测试工具。它将对用户指定的CPU数量的I/O,内存和硬盘的负载并报告它检测到任何错误。它用于自动压力测试和调试系统组件失败的唯一或更经常负荷时。它可以运行在x86,ppc64的,和PPC 32 GNU / Linux的,Tru64的,SPARC Solaris的,和其他平台。

使用示例:

   $ stress --cpu 2 --io 1 --vm 1 --vm-bytes 128M --timeout 10s --verbose     stress: info: [9372] dispatching hogs: 2 cpu, 1 io, 1 vm, 0 hdd     stress: dbug: [9372] (243) using backoff sleep of 12000us     stress: dbug: [9372] (262) setting timeout to 10s     stress: dbug: [9372] (285) --> hogcpu worker 9373 forked     stress: dbug: [9372] (305) --> hogio worker 9374 forked     stress: dbug: [9372] (325) --> hogvm worker 9375 forked     stress: dbug: [9372] (243) using backoff sleep of 3000us     stress: dbug: [9372] (262) setting timeout to 10s     stress: dbug: [9372] (285) --> hogcpu worker 9376 forked     stress: dbug: [9375] (466) hogvm worker malloced 134217728 bytes     stress: dbug: [9372] (382) <-- worker 9374 signalled normally     stress: dbug: [9372] (382) <-- worker 9373 signalled normally     stress: dbug: [9372] (382) <-- worker 9375 signalled normally     stress: dbug: [9372] (382) <-- worker 9376 signalled normally     stress: info: [9372] successful run completed in 10s
