Therefore, in terms of network management, it is necessary to understand the traffic status of our hosts and limit or increase bandwidth based on traffic.We can download the MRTG software from the http://www.mrtg.org. Go to http://www.stat.ee.ethz.ch/mrtg/to get the output result of the mrtgtraffic monitoring chart.MRTG is written in Perl and uses zlib, Gd, and PNG functions (zlib is used to compress charts and GD is used to draw charts ).

, not a temporary phenomenon. (3) when the system load continues to exceed 0.7, you must start investigating where the problem is and prevent the situation from deteriorating. (4) when the system load continues to exceed 1.0, you must find a solution to reduce this value. (5) when the system load reaches 5.0, it indicates that your system has a very serious problem, does not respond for a long time, or is close to a dead end. 2. view the total number of server

Partial reprint 51942281The iostat command is used to monitor system input and CPU usage. It is characterized by the reporting of disk activity statistics, as well as the reporting of CPU usage. like Vmstat, Iostat also has a weakness, that is, it cannot analyze a process in depth, only the overall situation of the system.

If there is a lot of interruptions, kernel takes a lot of time to deal with interrupts. You can check/proc/interrupts to know which CPU the interrupt occurred on.CPU UtilizationCpuutilization, a very intuitive concept, the CPU has 7 states at any on

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

General operating system performance mainly related to the main problems are: Processor usage, memory footprint, disk i/0 operations, and network traffic.To view Windows performance, in most cases through Windows Task Manager, you can eject task Manager by typing: taskmgr in the command line. Task Manager can view: CPU usage, memory usage, and network traffic.Using Windows Task Manager is intuitive and the UI works fine. However, there are some drawba
