Article Title: CPU for Linux performance monitoring. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. As we discussed earlier, the performance of any system is baseline-based, and the performance of CPU

time may be caused by a single (or multiple) overloaded processor, many other tools can be used to narrow the cause of the load. to delve deeper into processor usage, the 3 tools described below can provide many different understandings of CPU utilization: Vmstat, Iostat, and top. Each of these tools focuses on different aspects of system monitoring, but can get a different view of the current usage of

1, IntroductionMpstat isMultiprocessor StatisticsThe abbreviation, isreal-time system monitoring tools。 Its reports are some of the CPU's statistics, which are stored in the/proc/stat file. In a multi-CPUs system, it not only can view the average status information of all CPUs, but also can view the information of specific CPU. Mpstat's biggest feature is the ability to view statistics for each compute core

Mpstat Mpstat is the abbreviation of multiprocessor statistics, a real-time system monitoring tool. Some statistical information about the report and CPU, which is stored in the/proc/stat file. In a CPUs system, it is not only possible to view the average information of all CPUs, but also to view information about a particular CPU. The biggest feature of Mpstat

Whether it is the home computer or the server has been the constant need to solve the problem is cooling, and in peacetime server running process How to know the server's internal cooling system is healthy, temperature is normal can be monitored by lm_sensors tools, lm_ Sensors is a Linux hardware monitoring software, which can be used to print temperature sensor information, help us to monitor the motherbo

Shell monitors cpu, memory, and load average, records the log, and sends an email to the Administrator when the load is under pressure. Principle: 1. Obtain the value of cpu, memory, and load average. 2. Determine whether the value exceeds the custom range, for example (CPU> 90%, Memory 3. If the value range is exceeded, send an email to the Administrator. The m

Note: There is a file embedded within this post, please visit this post to download the file.The data center does not have a temperature alarm device. I use this method to control the temperature of the data center. If there is only one alarm, a single machine failure can be considered. If there are several alarms at the same time, it can be considered that there is a problem with the air conditioner in the data center. The specific implementation method is as follows: Environment: monitored: Ce
