1. Overview The sar command displays system usage reports through data collected from system activities. These reports are made up of different sections, each containing the type of data and when the data was collected. The default mode of the sar command displays the CPU usage at different time increments for various resources accessing the CPU (such as users, systems, I/O schedulers, etc.). Additionally, it displays the percentage of idle CPU for a given time period. The average value for each data point is listed at the bottom of the report. sar reports collected data every 10 minutes by default, but you can use various options to filter and adjust these reports. Similar to the uptime command, the sar command can also help you monitor the CPU load. Through sar, you can understand the occurrence of excessive load

In Win11 system, you can enable or disable Hyper-V enhanced session mode through commands. This article will introduce how to use commands to operate and help users better manage and control Hyper-V functions in the system. Hyper-V is a virtualization technology provided by Microsoft.

It can be used to implement event notification, that is, to deliver events through a file descriptor. eventfd contains a 64-bit unsigned integer counter maintained by the kernel. The process can read/change the counter value by reading/writing this file descriptor to achieve inter-process communication. What are the advantages of eventfd? It has the following features

What is the correct way to restart a service in Linux?
