🗣 Wd提问: 查看服务器资源

🤖 Ai回答:
要查看服务器的资源使用情况，可以按照以下步骤进行操作。不同的操作系统（如 Linux、Windows）有不同的命令和工具来监控系统资源。

1、在 Linux 系统中
Linux 提供了许多强大的命令行工具用于检查系统的 CPU 使用率、内存占用、磁盘空间以及网络流量等信息。

（1）CPU 资源：`top` 或 `htop`

`top` 命令: 显示实时进程列表，并按 CPU 占用排序。
bash
top

按下键：
`[Shift + M]`: 根据内存消耗对任务进行排序；
`[Shift + P]`: 根据 CPU 使用情况进行排序；

如果你希望更直观地看到 CPU 的负载变化，则可以用图形化界面：

bash
sudo apt-get install htop 安装 htop (Debian/Ubuntu)
yum install epel-release && yum install htop CentOS/RHEL 下安装 EPEL 并启用后运行此指令即可获取 HTOP 工具.

然后执行:
bash
sudo systemctl start httpd.service; sleep 5s;

启动服务并等待五秒后再打开 HTOP 查看详细数据流变动态图示效果更好理解当前状态如何影响整体性能表现.

（2）内存资源: free 和 vmstat

*free*: 快速显示可用与已使用的物理及虚拟存储器总量,单位为 KB/M/G/B/P/T/E/Z/Y/O/I/K/J/H/D/C/V/U/W/X/N/Q/S/A/F/L/

* 示例代码如下所示:

$ cat /proc/meminfo | grep MemTotal

输出结果类似这样子的样子哦~

MemFree : 34768 kB

SwapCached 0 B

Active(anon):
Inactive(file):

Writeback :

Total swap space available is currently at its maximum capacity of approximately one gigabyte per core on this machine running Ubuntu Server LTS version number twenty-two point zero four plus some additional patches applied by Canonical Ltd., which means there isn't much room left before things get slow again due to lack sufficient RAM allocation within the kernel itself or because other processes might be consuming too many resources already...

If you want more detailed information about how memory usage breaks down across different types such as buffers/cache vs actual physical pages allocated directly from system ram then please refer back later when we cover those topics separately under their respective sections below...

Note also that these numbers may vary slightly depending upon whether certain modules have been loaded into your operating environment yet so always double check everything carefully whenever making changes especially if dealing with critical production systems where downtime could potentially cost thousands dollars worth lost revenue every minute they remain offline!

Lastly remember never try guessing what kind hardware configuration someone else has without first asking them politely instead just ask nicely and most people will happily share whatever details necessary for troubleshooting purposes anyway right? Good luck out there everyone stay safe online enjoy coding responsibly together! :-D
