Bug Description

environment: Bionic-Stein

Upon changing the gnocchi-archive-policy config option, new resources created do not result in the new metrics in gnocchi using the defined archive-policy.

This is because the correct way to set the archive policy is through the pipeline.yaml[0] file which is not present, therefore it always uses the default URL "gnocchi://" which picks up the default archive-policy ceilometer-low.

By manually creating the file pipeline.yaml and setting the URL to gnocchi://?archive_policy=my_policy and restarting ceilometer services, metrics of new resources are then created with the my_policy archive policy.

here an easy step by step on how to workaround:

1) copy the contents of /usr/lib/python3/dist-packages/ceilometer/pipeline/data/pipeline.yaml to /etc/ceilometer/pipeline.yaml

2) append to gnocchi:// "?archive_policy=<your_archive_policy_name"

3) restart ceilometer services
