Specifying archive policy name breaks Gnocchi publisher

[Mark Beierl]

Looking at this guide: https://jaas.ai/ceilometer/269#charm-config-gnocchi-archive-policy, it is possible to change the name of the archive policy. Most Ceilometer/Gnocchi installations seem to use 'ceilometer-low' as the name.

However, if the charm is deployed with an option to use that name, the publisher fails.

Charm:

    options:
      enable-all-pollsters: true
      polling-interval: 60
      gnocchi-archive-policy: ceilometer-low

Error in ceilometer logs:

Hi Mark,

On the surface, it looks like you are using an OpenStack version where this archive policy is not defined yet.

More specifically, ceilometer packaged in the Queens UCA does not have ceilometer-low in gnocchi_resources.yaml:

https://git.launchpad.net/~ubuntu-server-dev/ubuntu/+source/ceilometer/tree/ceilometer/publisher/data/gnocchi_resources.yaml?h=stable/queens

Whereas ceilometer-low is only available as of OpenStack Rocky:
https://git.launchpad.net/~ubuntu-server-dev/ubuntu/+source/ceilometer/tree/ceilometer/publisher/data/gnocchi_resources.yaml?h=stable/rocky

The upstream commit that added it to OpenStack Rocky: https://github.com/openstack/ceilometer/commit/b96b16928

Could you please attach a sanitized bundle (`juju export-bundle` without secrets) or validate that you are using an OpenStack version >= Rocky?

This was tested against a rocky deployment:

diff --git a/bundle-bionic-rocky.yaml b/bundle-bionic-rocky.yaml

I will try this against Stein and see if it is a problem there too.
