Do you mean "measure the downtime" or some other form of analysis.

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.
