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 install memory-us...
that memory. The unshared memory (USS) plus a process's proportion of shared memory is reported as the PSS (Proportional Set Size). The USS and PSS only include physical memory usage. They do not include memory that has been swapped out to disk. Memory can be reported by process, by u...

动态查看一个进程的内存使用复制代码代码如下:1、top命令top -d 1 -p pid [,pid ...] //设置为delay 1s,默认是delay 3s 如果想根据内存使用量进行排序,可以shift + m(Sort by memory usage) 静态查看一个进程的内存使用复制代码代码如下:1、pmap命令pmap pid ...

3. Using pmap to Get Accurate Memory Information The pmap command reports the memory map of a process. We can use pmap to get the memory usage of a process and detail the libraries and binary files. By default, pmap will only show us the processes that we own. If we want to see inf...
Massif, one of theValgrindtools, measures the heap memory used by a specific program. A simplevalgrind massifone-liner to depict peak memory usage of the ‘top‘ process will look like: $ valgrind --tool=massif --pages-as-heap=yes --massif-out-file=massif.out top; grep mem_heap_B mas...
