I try to implement the Autoscaling using with Ceilometer. I am able to create stack with heat template and I stree the CPU untilization morethan 90% . but still scaling is not happening. Also I see one issue Ceilometer alarm state is "insufficient data"

[root@icmcs ceilometer]# ceilometer alarm-list +--------------------------------------+-------------------------------------------------+-------------------+----------+---------+------------+-----------------------------------------------------------------+------------------+ | Alarm ID | Name | State | Severity | Enabled | Continuous | Alarm condition | Time constraints | +--------------------------------------+-------------------------------------------------+-------------------+----------+---------+------------+-------------------------------------------------- | cacbac69-14eb-49c1-b1b1-042f8e0d3e52 | demo-autoscaling1-cpu_alarm_low-imzkpfqywqvn | insufficient data | low | True | True | cpu-util < 15.0 during 1 x 50s | None | | d24134d8-d484-4485-93d3-acf0e1f33471 | demo-autoscaling1-cpu_alarm_high-2jmfxxkuil2o | insufficient data | low | True | True | cpu-util > 50.0 during 1 x 50s | None | +--------------------------------------+-------------------------------------------------+-------------------+----------+---------+------------+--------------------------------------------------

Ceilometer cpu_util alos not capturing. [root@icmcs ceilometer]# ceilometer statistics -m cpu_util +--------+--------------+------------+-----+-----+-----+-----+-------+----------+----------------+--------------+ | Period | Period Start | Period End | Max | Min | Avg | Sum | Count | Duration | Duration Start | Duration End | +--------+--------------+------------+-----+-----+-----+-----+-------+----------+----------------+--------------+

I appreciate help on this. thanks.
