Hi,
I tried to switch to Ec2Snith. Although it correctly found the region:
INFO 23:18:00,643 EC2Snitch using region: eu-west, zone: 1a.
it started to report NullPointerException every second:
ERROR 00:23:40,268 Internal error processing get_slice
java.lang.NullPointerException

Am I doing something wrong?
Thanks,
