[Xen-users] Dom U bandwidth monitoring - pmacct, bandwidthd?

["Matthew Law" <matt@xxxxxxxxxxxxxxxxxx>]

I am looking for a way of recording internet bandwidth used by the domUs
on my servers.  I own the servers and switches but not the routers.  I
have multiple switches with aggregated links to the dom0s such that
depending on which one of the HSRP nodes they are currently connected to,
only one switch will be the uplink path to the internet. I hope this is
making sense - resisting the urge to draw an ascii network diagram :-)

Anyway, I wanted to ask if other people here have a similar topology and
how they account for bandwidth? - my initial thoughts are to have a SPAN
port on each switch mirroring the uplink and connect a separate box into
that which runs bandwidthd.  The only problem I can forsee is when the
HSRP moves from one switch to the other I might have a bit of a mess on my
hands.  Is pmacct a better option? Or perhaps something else?

I would prefer to do this at the egress point rather than run some kind of
accounting process on each dom0.

Grateful for any advice.


Thanks,

Matt.
