日常管理中使用需要经常查看服务器状态和性能，比如IO占用情况，及内存使用情况，硬盘，CPU等等。网络上搜罗了一下，这个dstat软件还是比较不错能满足日常分析。本人采用的是X64系统，在CentOS6.2系统下采用yum进行安装dstat软件
默认情况它会收集 cpu、disk、net、paging、system 数据，一秒钟收集一次
[root@kiccleaf ~]# dstat #运行命令是否已经安装
-bash: dstat: command not found #没有找到此命令
[root@kiccleaf ~]# yum install dstat #进行安装

Usage: dstat [-afv] [options..] [delay [count]]
Versatile tool for generating system resource statistics
Dstat options:
-c, --cpu enable cpu stats 显示CPU情况
-C 0,3,total include cpu0, cpu3 and total
-d, --disk enable disk stats 显示磁盘情况
-D total,hda include hda and total
-g, --page enable page stats
-i, --int enable interrupt stats
-I 5,eth2 include int5 and interrupt used by eth2
-l, --load enable load stats
-m, --mem enable memory stats 显示内存情况
-n, --net enable network stats 显示网络情况
-N eth1,total include eth1 and total 可以指定网络接口
-p, --proc enable process stats
-r, --io enable io stats (I/O requests completed)
-s, --swap enable swap stats 显示swap情况
-S swap1,total include swap1 and total 可以指定多个swap
-t, --time enable time/date output
-T, --epoch enable time counter (seconds since epoch)
-y, --sys enable system stats
--aio enable aio stats
--fs, --filesystem enable fs stats
--ipc enable ipc stats 报告IPC消息队列和信号量的使用情况
--lock enable lock stats
--raw enable raw stats
--socket enable socket stats
--tcp enable tcp stats
--udp enable udp stats
--unix enable unix stats
--vm enable vm stats
--plugin-name enable plugins by plugin name (see manual)
--list list all available plugins
-a, --all equals -cdngy (default) 使用-cdngy 缺省的就是这样显示
-f, --full automatically expand -C, -D, -I, -N and -S lists 使用 -C, -D, -I, -N and -S 显示
-v, --vmstat equals -pmgdsc -D total 使用-pmgdsc -D 显示
--bw, --blackonwhite change colors for white background terminal
--float force float values on screen
--integer force integer values on screen
--nocolor disable colors (implies --noupdate)
--noheaders disable repetitive headers 只显示一次表头以后就不显示了,使用重定向写入文件时很有用
--noupdate disable intermediate updates
--output file write CSV output to file
delay is the delay in seconds between each update (default: 1)
count is the number of updates to display before exiting (default: unlimited)
较为长用的命令，来观察系统运行情况
