byte - 在 Solaris 下，如何获取 NIC 输入和输出字节？

Question

在 Solaris 下，我怎样才能像在 Linux 中一样获取 NIC 输入和输出字节，我可以用它cat /proc/net/dev来选择两次数据然后计算差异？

Answer 1

您可以使用 kstat，传递您的接口名称，例如：

kstat -n qfe3 1 2 | egrep "snaptime|64"
        ipackets64                      7661398
        obytes64                        1483251857
        opackets64                      6584034
        rbytes64                        4540752924
        snaptime                        5803795.88609375
        ipackets64                      7661404
        obytes64                        1483252829
        opackets64                      6584040
        rbytes64                        4540753320
        snaptime                        5803796.92155328

这里的间隔是一秒（准确地说是 1.03545953），obytes 显示传出字节，rbytes 显示传入字节。

确保选择正确的接口，例如：

$ uname -a
SunOS s10u10.local.net 5.10 Generic_147441-23 i86pc i386 i86pc
$ ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
e1000g0: flags=1004843<UP,BROADCAST,RUNNING,MULTICAST,DHCP,IPv4> mtu 1500 index 2
        inet 10.0.2.15 netmask ffffff00 broadcast 10.0.2.255
e1000g0:100: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 192.168.10.254 netmask ffffff00 broadcast 192.168.10.255
e1000g1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
        inet 192.168.56.2 netmask ffffff00 broadcast 192.168.56.255
$ kstat -n e1000g1 | egrep "64|snaptime"
        ipackets64                      82
        obytes64                        840
        opackets64                      14
        rbytes64                        15792
        snaptime                        1600.258974202

试试 Tim Cook 的 nicstat：http: //sourceforge.net/projects/nicstat/
