Hi Mark, Hi,
I didn't follow the whole thread but had the same problem when using net-snmp
with bridges (an I see peth0 and that rang the bell). The problem seems to be
that net-snmp does not like nics with same ips (I didn't find very much on
that topic). You should see some errors from net-snmp in the syslogs of your
managed servers. What does your syslog say?
I solved it by changing the bridge configuration from the scripts provided by
xen /etc/xen/scripts/network-bridge to using ifcfg bridges. Then cacti could
monitor the interfaces like normal.
Hope that helps.
Regards marc.
I don't think that's quite the case. Each interface has a different IP. In fact, if each interface had the same IP, then the whole network in that IP range, on the server, would be problematic - and there would be not traffic flowing through. For TCP/IP to work properly, each interface has to have a unique IP address (and depending on the subnet, a different subnet mask / gateway pair as well).
Each XEN interface is also a seperate interface, but it uses the bridgetools to work properly - i.e. connect directly to the external network.
