uptime measurement

Uptime command usage is very simple: enter uptime directly.There is also a parameter-V, which is used to query the version. (Note that the letter is uppercase V)[Linux @ localhost]$ Uptime–vProcps version 3.2.7[Linux @ localhost]$ uptimeDisplay results as:10:19:04 up 257 days, 18:56, users, load average:2.10, 2.10,2.09Display Content Description:10:19:04//System

The shocking fact is that even common metrics such as productivity do not have a simple definition. Even the formula we often use: Productivity = work products/workload (work products can be code lines, functional points, or anything that can be counted, such as the number of document pages) all are errors. If you try to use productivity for measurement normally, you should first divide it into the following two types of

processing performance as another host. Of course, the actual situation will be much more complicated. Different Quantities of cache, processor frequency and other factors may cause performance differences. However, even if the actual performance of these factors is slightly different, the system still calculates the average load based on the number of cores of the processor. This gives us two new rules: • "How many cores is the load" rule: in multi-core processing, your system average value sh

This command has two major uses, one is to see if your machine has recently been restarted, or because of hardware, and so on, the other is to look at your CPU load.

Python _ distance measurement, python Distance Measurement The reason for writing this is actually to hope to have some concepts about distance. Of course, this is also very basic, but just a thousand miles of travel begins with a single step. All kinds of path algorithms, such as a *, will use this. There are three ways to measure the distance. 1. Euclidean distance, which is the most commonly used Distanc

In Linux, commands such as uptime, W, and top all have an average system load of average output. What is the average system load? The average system load is defined as the average process tree in the running queue within a specific time interval. If a process meets the following conditions, it will be in the running queue:-It has no results waiting for I/O operations.-It does not take the initiative to enter the waiting state (that is, it does not ca
