I have used "ping -i 0.1 -c 100 -n ${address} > ping.txt", and then check how many pings went missing to analyse the downtime. I would suggest that you run ping on a separate machine, as in my experience, at least for localhost migration, the dom0 cpu-load is such that ping doesn't necessarily get to run when it wants/needs to. If you had some other analysis in mind, do explain further, and I'm sure someone can come up with a good suggestion. -- Mats
