Monitoring Linux system performance every day is a daunting task for every system/network administrator. After 5 years of Linux system administrators in the IT industry, I found it's not easy to monitor and keep the system up and running, so I've summed up 8 very useful command-line tools for Linux/unix system administrators. These commands support all Linux systems and can be used not only to monitor the s

When there is a problem with the Linux system, we not only need to look at the system log information, but also use a lot of performance monitoring tools to determine what part (memory, CPU, hard disk ...). ) out of the question. In the Linux system, all the operating parameters are saved in the virtual directory/proc, in other words, we use the Performance

about 10.5, and every 3 seconds disk reads about 62KB, writes about: 110KB, this value is not an accurate value, why? Know why? Because of the time period problemThe best test is to find the average number of times or use the method to find the current valueAs shown below:650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M02/6B/86/wKiom1Uvfk2jn_KzAAC-70HOJzU414.jpg "title=" 6.png " alt= "Wkiom1uvfk2jn_kzaac-70hojzu414.jpg"/>There are many more detailed extensions for Iostat, with the-X opt

System optimization is a complex, complex, and long-term task. The following subsystems are usually monitored: CPU, Memory, IO, Network, etc. I. CPU performance indicators CPU utilization: User Time Context switch: It is associated with the CPU usage. If the CPU usage is in good state, a large number of context switches are acceptable. Runnable queue: three threads per processor.Monitoring tools Vmstat $ Vmstat 1 First, let's look at a field that can

When the memory is low:All dirty pages are not written to disk at this time, and when you write about 1024 pages each time, you know that the free memory meets your needs.3, when the write operation found that dirty pages more than a certain proportionWhen the amount of system memory in a dirty page exceeds "/proc/sys/vm/dirty_background_ratio",

The basic functions of the top command and ps command are the same, displaying the current process of the system and other conditions. However, the top command is a dynamic display process, that is, you can press the key to continuously refresh the current state. Such? The front-end executes this command, and it will exclusively occupy the front-end until the user terminates the program. More accurately, the top command provides real-time monitoring o

Both are designed to improve IO performance and are managed by the OSThat is, the data in this line of MEM shows how the memory is being used from a system point of view.FO[3][2]: The memory the application has actually used.FO[3][3]: The memory that the ap

In Web site performance optimization, we often have to check the various indicators of the server in order to quickly find the black sheep. In most cases, we use monitoring software such as cacti, Nagois, or Zabbix, but this kind of software is cumbersome to install, and in a small server we want to find out as quickly as possible, or use some of the commands that Linux provides. 1. Memory Check: free-m N
