Hi Peter,

Sure, here it is:
-------------------------------8<--------------------------------------
#!/bin/sh

export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11"

xm list | awk '{print $1, $2}' > /tmp/xm.now &&
[ "`cat /tmp/xm.now 2>/dev/null | md5sum`" != "`cat /tmp/xm.last 2>/dev/null | md5sum`" ] &&
diff --normal /tmp/xm.last /tmp/xm.now | grep -E '<|>' &&
/etc/init.d/snmpd restart

mv -f /tmp/xm.now /tmp/xm.last
-------------------------------8<--------------------------------------

Hi Peter,

This is because the OID of the interface gets changed. I have done a little
script that restarts snmp if the domUs get restarted/stopped/started.

Good luck,
Adrian

Hi

am trying to monitore domU traffic using CACTI + net-smp on dom0.

It runs well untill the domU get restarted.Than the graphs stops.

Every domU get vifname specified so its same after the reboot.
In net-smp i see several "vifuser01", only one is stated as up and
they are wilth different IDs.

I don't know how to troubleshoot this problem.

Anybody facing same behaviour?

BR

Peter Braun
