[Bug 1780088] Re: Ceilometer Pike packages should require python-jsonpath-rw-ext 1.1.3 on 16.04

[Corey Bryant]

Hi Cory,

Thanks for reporting this.

Upper-constraints for stable/pike has 1.1.2.
https://github.com/openstack/requirements/blob/stable/pike/upper-constraints.txt

In general we're very conservative with introducing any new features to
stable releases. We may instead need to backport specific patches to
enable whatever it is that's needed. I'll take a look.

Thanks,
Corey

Title:
  Ceilometer Pike packages should require python-jsonpath-rw-ext 1.1.3
  on 16.04

Status in Ubuntu Cloud Archive:
  New

Bug description:
  I'm using the Ubuntu Cloud Archive to install Pike packages on 16.04.

  With the default configuration of Ceilometer and Gnocchi I am seeing
  the following message when trying to process metrics from Keystone:

      WARNING ceilometer.dispatcher.gnocchi [-] metric $.payload.outcome
  - $.payload.outcome + 'identity.authenticate.' + $.payload.outcome is
  not handled by Gnocchi

  These metrics from Keystone are never received by Gnocchi.

  When I asked about this on the #openstack-telemetry IRC channel the
  developers found that this message is the result of an older version
  of the python-jsonpath-rw-ext package being installed from the Pike
  Cloud Archive. The xenial-updates/pike Ubuntu Cloud Archive repository
  has version 0.1.9 of python-jsonpath-rw-ext, where the developers
  suggest that version 1.1.3 is needed [1]. Specifically, this is
  required for the `identity.authenticate` event_type defined in the
  default packaged version of /usr/lib/python2.7/dist-
  packages/ceilometer/data/meters.d/meters.yaml.

  It appears the 1.1.3 packages for python-jsonpath-rw-ext are already
  present in the Queens archive [2]. Could these be made available in
  the Pike repository as well?
