CPU的参数详解: us(user time) 表示CPU执行用户进程的时间,包括ni时间。通常我们只看这项。 sy(system time) 表示CPU在内核运行时间,包括IRQ和softirq时间,系统CPU占用率高,表明系统某部份存在瓶颈,通常值越低越好。 wa(waiting time) CPI在等待I/O操作完成所花费的时间,系统不应该花费大量时间来等待I/O操作,否则说明I/O存在问题。 id(idle time) 系统处于空闲期,等待进程运行。 ni(nice time) 系统调整进程优先级所花费的时间。 hi(hard irq time) 系统处理硬中断所花费的时间。 si(softirq time) 系统处理软件中断所花费的时间。 st(steal time) 被强制等待虚拟CPU的时间,此时hypervisor在为另一个虚拟处理器服务。 Processor/% Processor Time 阀值:处理器的阀值一般设为85%。 含义:表示处理器活动的主要指标。高数值并不一定是坏事,但是如果其他处理器相关的计数器(比如% Privileged Time 或者 Processor Queue Length)线性增加的话,高CPU使用率就值得调查了。 Processor/% Privileged Time 阀值:如果数值持续大于75%就表示存在瓶颈。 含义:表示一个线程在特权模式下所使用的时间比例。当你的程序调用操作系统的方法(比如文件操作,网络I/O或者分配内存),这些操作系统的方法是在特权模式下运行的。 Processor/% Interrupt Time 阀值:取决于处理器 含义:表示处理器接收处理硬件中断所使用的时间比例。这个值间接指出产生中断的硬件设备活动,比如网络变化。这个计数器显著增加的话表示硬件可能存在问题。 System/Processor Queue Length 阀值:平均值持续大于2那么表示CPU存在瓶颈 含义:如果就绪的任务超过处理能力线程就会被放进队列。处理器队列是就绪但是未能被处理器执行的线程的集合,这是因为另外一个线程正在执行状态。持续或者反复发生2个以上的队列则明确的表示存在处理器瓶颈。你也能通过减少并发取得更大的吞吐量。 System/Context Switches/sec 阀值:按照通常的规律,Context […]

We are first going to set the property “Download update files to this server only when updates are appoved”, turn off all update languages, and then set the only update language to English. At the end, this would all be pointless if we didn’t […]
