一、工具介绍 memory-usage是一个简洁且易用的命令行工具,可以快速查看系统的内存使用情况。该工具基于Linux系统的内存管理机制,通过实时监控进程的内存使用情况,为用户提供一个直观的视角。 二、使用方法 安装memory-usage 在Linux系统中,你可以使用以下命令来安装memory-usage: sudo apt-get update sudo apt-get ins...
In this guide, we will focus on using different CLI tools to check memory usage per process in Linux. By the end of this guide, you will have a better understanding of how to monitor and optimize memory usage on your Linux system, regardless of the method you choose. You can also read...
Finally, one more instance was killed, leaving one instance. As expected, the PSS of the remaining instance grew further, taking on the full weight of the glib library memory. But interestingly the USS number also grew. It seems that if a library is only used by a single process, it wil...
http://opentips.blogspot.com/2008/01/linux-process-memory-usage.html The following shell script is used to monitor the memory usage of a process. Save the following script in a file (for ex, memusage.sh) and run it with the process name you want to monitor. for ex, ./memusage.sh ...
It is often important to check memory usage and memory used per process on servers so that resources do not fall short and users are able to access the server. For example a website. If you are running a webserver, then the server must have enough memory to serve the visitors to the ...
所以,PFRA整体上是策略,还有很多经验值。 2,watermark 如前文《物理内存管理》提到,每个memory zone都有watermark,如果低于了watermark,Linux就考虑回收内存了。 在linux-4.0.4/mm/page_alloc.c中: 分配page之前,先判断zone的watermark是否是OK的(by zone_watermark_ok),如果watermark不满足,则先尝试回收(by zone_...
