首先您执行一次ifconfig -a命令，找到RX bytes:1973174498 (1.8 GiB)  TX bytes:125331670357 (116.7 GiB)，记录下来。

[root@deepvps]# ifconfig -a
lo        Link encap:Local Loopback 
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:9009 errors:0 dropped:0 overruns:0 frame:0
          TX packets:9009 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:556436 (543.3 KiB)  TX bytes:556436 (543.3 KiB)

venet0    Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 
          inet addr:127.0.0.1  P-t-P:127.0.0.1  Bcast:0.0.0.0  Mask:255.255.255.255
          UP BROADCAST POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1
          RX packets:46206817 errors:0 dropped:0 overruns:0 frame:0
          TX packets:85906088 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:1973174498 (1.8 GiB)  TX bytes:125331670357 (116.7 GiB)

 

然后，相隔24小时，再执行一次ifconfig -a命令，找到RX bytes:2283947894 (2.1 GiB)  TX bytes:144706254769 (134.9 GiB)

[root@deepvps]# ifconfig -a
lo        Link encap:Local Loopback 
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:9009 errors:0 dropped:0 overruns:0 frame:0
          TX packets:9009 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:556436 (543.3 KiB)  TX bytes:556436 (543.3 KiB)

venet0    Link encap:UNSPEC  HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 
          inet addr:127.0.0.1  P-t-P:127.0.0.1  Bcast:0.0.0.0  Mask:255.255.255.255
          UP BROADCAST POINTOPOINT RUNNING NOARP  MTU:1500  Metric:1
          RX packets:53386450 errors:0 dropped:0 overruns:0 frame:0
          TX packets:99272586 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:2283947894 (2.1 GiB)  TX bytes:144706254769 (134.9 GiB)

很明显，后者比前者多了134.9-116.7 = 18.2GB，这就说明24小时的流出流量TX是18.2GB，一个月大概就是18*31=560GB流量。怎么样，估算Linux vps的流量很方便吧！顺便说一下RX是流入流量，对90%作网站的linux vps来说，一般都很小，可忽略不计。
