1.查看cpu
[root@m01 ~]# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 1 On-line CPU(s) list: 0 Thread(s) per core: 1 Core(s) per socket: 1 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 …………
2.查看cpu负载
简单的命令
[root@m01 ~]# uptime 18:54:54 up 16:22, 2 users, load average: 0.00, 0.02, 0.05
top工具(实时动态查看系统负载 快捷键 z 加颜色 x 高亮显示排序区域 < > 向左,向右切换)
htop工具(需要epel源yum下载)
3.查询内存free命令
[root@m01 ~]# free -h total used free shared buff/cache available Mem: 1.8G 442M 654M 9.6M 726M 1.2G Swap: 1.0G 0B 1.0G
vmstat命令
[root@m01 ~]# vmstat procs -----------memory---------- ---swap-- -----io---- -system-- ------cpu----- r b swpd free buff cache si so bi bo in cs us sy id wa st 2 0 0 670488 4136 739780 0 0 5 144 170 198 1 1 97 1 0
4.磁盘相关
查看磁盘空间
[root@m01 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 18G 1.8G 17G 10% / devtmpfs 903M 0 903M 0% /dev tmpfs 912M 0 912M 0% /dev/shm tmpfs 912M 8.7M 904M 1% /run tmpfs 912M 0 912M 0% /sys/fs/cgroup /dev/sda1 1014M 135M 880M 14% /boot tmpfs 183M 0 183M 0% /run/user/0
查看磁盘IO
5.网络相关
查询网卡流量iftop
查看某一块网卡:iftop -i eth1
查看进程的网络占用nethogs
