Hi,

Many thanks, that helped. I no longer see those errors in the log.

However, even though cpu_util metric data gets inserted to the ceilometer
db with values bigger than the threshold defined for scaling-up in the
template (template used can be seen here:
https://bugs.launchpad.net/heat/+bug/1223710), no actions get triggered.
All I see in the ceilometer-alarm-singleton log are "initiating evaluation
cycle on 2 alarms" entries. No entries in ceilometer-alarm-notifier log.

Any ideas / pointers what could be the reason for this...?
