linux performance tuning books

Nmon (also known as Nigel rsquo; sMonitor) is a very common system performance monitoring tool developed by IBM engineer nielgriiths and suitable for AIX and Linux operating systems. This tool can directly display the resource utilization of the current operating system on the screen to help you identify system bottlenecks and assist in system tuning. Thanks to

In previous posts on vm.swappiness and using RAM disks we talked about how the memory on a Linux guest are used for the OS itself (the kernel, buffers, etc), applications, and also for file cache. File caching is an important performance improvement, and read caching are a clear win in most cases, balanced against APPL Ications using the RAM directly. Write caching is trickier. The

If you're looking for a very easy-to-use Linux performance monitoring tool right now, I highly recommend installing and using the Nmon command-line utility.Nmon Monitoring ToolsThe Nmon is a system administrator-oriented tuning and benchmarking tool that can be used to display performance data about the following:

Article Title: detailed introduction to 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. Networks are the most difficult to monitor in all subsystems. F

Linux performance monitoring command vmstat I. Overview Monitoring is usually divided into machine monitoring and service monitoring. Machine Monitoring is the basic monitoring to obtain the current running status of the system. service monitoring is the main purpose and the most important monitoring, machine Monitoring also exists for better service monitoring. In short, service monitoring is related to sp

Analysis toolsA free tool for analyzing AIX and Linux performance, the Nmon tool helps to display all of the important performance tuning information on one screen and dynamically update it. This efficient tool can work on any dumb screen, Telnet session, or even dial-up lines. In addition, it does not consume a lot of

a software package that includes a set of tools to monitor system performance and efficiency, such as sar, iostat, mpstat, and pidstat. These tools collect and analyze system performance data, such as CPU usage, hard disk, and network throughput data, which helps us determine whether the system is running normally, it is an effective assistant to improve system operation efficiency and secure operation of

A Linux operating system-based server runs at the same time, it will also characterize a variety of parameter information. In general, OPS and system administrators are extremely sensitive to these data, but these parameters are also important to developers, especially when your program is not working properly, and these clues often help to locate the tracking problem quickly.Here are just a few simple tools to view the relevant parameters of the syst
