linux cpu temp monitor

Monitoring the Raspberry Pi temperature through the Yeelink platform is the first lesson for many of your friends to get started. As a novice who was just starting out on the Raspberry Pi bare metal, in the absence of other hardware support, the Yeelink platform was the first step in learning the Raspberry Pi and learning smart hardware by monitoring the CPU temperature change of the Raspberry Pi.Implementation ideasThe idea of "Monitoring Raspberry P

Have seen a few times before the concept, but still always remember, simply write it down, easy to see in the future ~The so-called clock time is also called the wall clock time, it is the total number of clocks that the process is running, and its value is related to how many processes are running concurrently in the system, although it is generally measured when there are no other activities in the system when discussing clock time.User CPU Time: Is

The second result shows that the system is at 100% occupancy and has no idle time. From this comparison, We can determine whether the CPU usage should be optimized.2.0 Installing Monitoring ToolsMost *nix systems have a stack of standard monitor
