multitail 监控多个文件或命令

之前有同事希望在终端下开多个窗口查看服务状态，后来用xterm解决。
multitail可以很好的实现该功能，示例如下：
multitail --label "baidu.com: " -l 'ping baidu.com' --label "sina.com: " -l 'ping sina.com' --label "taobao.com: " -l "ping taobao.com" --label "sohu.com: " -l "ping sohu.com" --label "syslog: " /var/log/syslog -l "vmstat 1" -sw 100,100 -sn 3,3

-sw 用来设置有多少列，每列的大小
-sn 配合-sw/-s使用，设置每列的窗口数
-C 放在multitail后面，输出颜色

进入后，按h帮助，大写O清屏，更多功能大家自己发掘把，比如：只显示差异

安装使用yum或者apt, apt-get install multitail
