Hi all,

I desperately need some help with this. We provide XEN VPS's to our
clients in a hosting environment, and I need to measure the bandwidth
usage per VPS, since we charge per MB / per GB for bandwidth.

Someone suggested Cacti, and it works well, but every now and then it
stops monitoring each VPS's bandwidth (for no apparent reason), and
then I need to recreate the VPS's interface in Cacti - but this often
means that we've lost a few days (and close to a few GB's) traffic.

So, can someone please suggest something more reliable?

Each VPS's interface is named as follows:

vifkeit0  Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
          inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link
          UP BROADCAST RUNNING NOARP  MTU:1500  Metric:1
          RX packets:833111 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1330716 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:32
          RX bytes:1778333780 (1.6 GiB)  TX bytes:168951143 (161.1 MiB)

vifplut0  Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
          inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link
          UP BROADCAST RUNNING NOARP  MTU:1500  Metric:1
          RX packets:819054 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1390022 errors:0 dropped:82 overruns:0 carrier:0
          collisions:0 txqueuelen:32
          RX bytes:512295207 (488.5 MiB)  TX bytes:408377761 (389.4 MiB)

vifwise0  Link encap:Ethernet  HWaddr FE:FF:FF:FF:FF:FF
          inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link
          UP BROADCAST RUNNING NOARP  MTU:1500  Metric:1
          RX packets:689438 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1098542 errors:0 dropped:1478 overruns:0 carrier:0
          collisions:0 txqueuelen:32
          RX bytes:120582623 (114.9 MiB)  TX bytes:245914558 (234.5 MiB)




With Cacti, I just use the names vifwise0, vifplut0, etc.
