Waits which should not typically occur on a system (for example, 'wait for EMON to spawn') Queue Contains events that signify delays in obtaining additional data in a pipelined environment. The time spent on these wait events indicates inefficiency or otherproblems in the pipeline. It affects f...
wait_time属性 设置等待时间,默认值不等待,立即执行。 Locust支持4种方式设置wait_time属性。 为了便于理解实际意义,我把源码贴在了下面。 weight属性 设置创建类实例的权重,默认每个类创建相同数量的实例。 locustfile中可以有多个继承了User类的类。 命令行可以指定运行哪些类: $ locust -f locust_file.py WebUse...
TIME+:该进程启动后占用的总的CPU时间。 Command:进程启动的启动命令名称,如果这一行显示不下,进程会有一个完整的命令行。 top命令使用过程中,还可以使用一些交互的命令来完成其它参数的功能。这些命令是通过快捷键启动的。 <空格>:立刻刷新。 P:根据CPU使用大小进行排序。
cpu is idle while waiting for an I/O operation to complete。The time the CPU spends in this state is shown by the wait statistic. ⓔIdle Idel表示:CPU处于空闲状态时间比例。一般而言,idel + user + nice 约等于100% 此外,Linux中的top命令可实时显示系统的CPU使用情况。下图可看出Ganglia的gmond...
Wait(Int64, Int32) Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) Wait(Int64) Causes the current thread to wait until it is awakened...
