I try to create a new stack with only one resource which is a Ceilometer alarm. If a "meter" parameter is defined in a ceilometer, alarm is created with a correct query string: "metadata.user_metadata.stack == <stack_id>". There are situations when I need to create an alarm for a "meter", defined in pipeline.yaml. In this situation query string is changed to the "metadata.metering.metadata.user_metadata.stack == <stack_id>" value.
Steps to reproduce:
# cat alarm.yaml
heat_template_version: 2015-10-15
resources:
mem_alarm_high:
type: OS::Ceilometer::Alarm
properties:
description: Scale-up if the average memory usage >= 80% for 1 minute
meter_name: memory
statistic: avg
period: 60
evaluation_periods: 1
threshold: 80
alarm_actions:
matching_metadata: {"metadata.user_metadata.stack": {get_param: "OS::stack_id"}}
comparison_operator: gt
# heat stack-create -f alarm.yaml test-05311438
# ceilometer alarm-show 06ca7544-0c80-4029-8880-b573944a2102

So, all works fine. Now use memory_util:
# cat alarm.yaml
heat_template_version: 2015-10-15
resources:
mem_alarm_high:
type: OS::Ceilometer::Alarm
properties:
description: Scale-up if the average memory usage >= 80% for 1 minute
meter_name: memory_util
statistic: avg
period: 60
evaluation_periods: 1
threshold: 80
alarm_actions:
matching_metadata: {"metadata.user_metadata.stack": {get_param: "OS::stack_id"}}
comparison_operator: gt
# heat stack-create -f alarm.yaml test-05311439
# ceilometer alarm-show 397b1304-5d76-4f2c-b108-a1fe0b16b770
