Hi,

I met the problem when tried to be using autoscaling groups in heat
templates with havana (see:
https://bugs.launchpad.net/heat/+bug/1223710)

Can anyone confirm whether the autoscaling should already work with havana?

Currently the evaluation of the ceilometer alarm/meter data seems to be
failing:

ceilometer-alarm-singleton:
