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...
它包括进程使用的所有可用内存,包括交换空间、设备映射和分配但未使用的内存。 RES:Resident Set Size,常驻内存大小。这是该进程已分配的、位于RAM中的非交换区内存的大小,不包括被交换出去的部分。 SHR:Shared Memory,共享内存大小。指的是可被其他进程共享的内存量。 S:Process Status,进程状态。常见状态有: S(s...
Fig.02: Linux Check Amount Of Memory With atop Command htop command The program htop is an interactive process viewer. It is similar to top, but allows to scroll the list vertically and horizontally to see all processes and their full command lines. By default, the htop command is not inst...
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 ...
4.vmstat -s This will share the same results like meminfo but with less information. 5.top The top command is generally used to check memory and cpu usage per process
Importantly “device memory” can be removed at will by userspace unbinding the driver of the device. 3.3 典型架构(x86)上内存区域划分 对于x86机器,管理区(内存区域)类型如下分布 类型 区域 ZONE_DMA 0~15MB ZONE_NORMAL 16MB~895MB ZONE_HIGHMEM 896MB~物理内存结束 而由于32位系统中, Linux内核...
bool out_of_memory(struct oom_control *oc) { select_bad_process(oc); oom_kill_process(oc, "Out of memory"); } out_of_memory函数的代码逻辑还是非常简单清晰的,总共有两步,1.先选择一个要杀死的进程,2.杀死它。oom_kill_process函数的目的很简单,但是实现过程也有点复杂,这里就不展开分析了,大...
Finally, we start and enable the process: $ sudo systemctl restart zabbix-agent $ sudo systemctl enable zabbix-agent Next, we move on to adding a host for monitoring. 9. Using Zabbix for Memory Monitoring On the left sidebar on the frontend webpage, we select theHostsoption: ...
A VM area is any part of the process virtual memory * space that has a special rule for the page-fault handlers (ie a shared * library, the executable area etc). */ struct vm_area_struct { /* The first cache line has the info for VMA tree walking. */ // 分别用来保存该虚拟地址...
How Do I Check My Top 10 CPU Usage Linux?To check your top 10 CPU usage on Linux, you must use the top command in the terminal. It provides a real-time view of the processes running on your system, including the amount of CPU and memory each process consumes each second....
