watch -d 'ls -l|grep scf' 实例5:10秒一次输出系统的平均负载 命令: watch -n 10 'cat /proc/loadavg' 一、使用wtach + 命令 查看网卡流量 watch ifconfig watch cat /proc/net/dev 能看查看各网卡的接收和发送的的数据包/字节情况的统计流 watch -n 1 "/sbin/ifconfig eth0 | grep bytes" 二...
3. 选择监听测试的接口,所有接口。 4.开启监听状态日志,系统默认日志路径。/var/log/iptraf/ip_traffic.log 4. 运行之后,开启进行监听网卡流量 5.iptraf参考用法: man iptraf 查看 此外还有很多工具命令可以查看: watch命令: watch -n 1 "/sbin/ifconfig eth0 | grep bytes"。

NetHogs is a small ‘net top’ tool. Instead of breaking the traffic down per protocol or per subnet, as most tools do, it groups bandwidth by process. NetHogs does not rely on a special kernel module to be loaded. If there’s suddenly a lot of network traffic, you can fire up NetHo...
