'alarm-listener' in Aodh would be deployed if you use charm-aodh.
It expects that ceilometer publish events with 'alarm.all' topic,
then it can evaluate alarm criteria pre-configured by users.

This patch makes ceilometer publish events for event-driven alarm
evaluation in Aodh.

With the release of 4.2.0 of keystonemiddleware using the
in-process token cache is no longer recommended. It is recommended
that a memcache backend to store tokens is used instead,

This installs and configures memcache and configures neutron-server
to use memcache for token caching.

If the charm enables https then apache is used to terminate ssl. As
part of this Apache listens on the port that the ceilometer API port
was listening on and the API service shuffles down to a lower port. If
the services are restarted one at a time and Apache goes first then
Apache will try and bind to the port the API service is listening on
because the API service has not yet been restarted to pick up its
new port.

service_credentials is used for the keystoneauth1.session.Session

Partial-Bug: #1624173

Ceilometer switched to using wsgi_script to generate the
ceilometer-api binary; this resulted in a few packaging changes,
including one which means the listen port for Ceilometer API is
set via the systemd unit, rather than the ceilometer.conf
configuration file.

Add systemd override file handling for ceilometer-api, including a
small workaround which ensures that the systemd daemon loads the
override configuration file when it changes (only possible during
config-changed with enabling SSL support).

This charm should switch to using Apache + mod_wsgi next cycle, at
which point all of that can just be dropped.

Juju 2.0 provides support for display of the version of
an application deployed by a charm in juju status.

Insert the os_application_version_set function into the
existing assess_status function - this gets called after
all hook executions, and periodically after that, so any
changes in package versions due to normal system updates
will also be reflected in the status output.

This review also includes a resync of charm-helpers to
pickup hookenv and contrib.openstack support for this
feature.

All OpenStack Charms now contain identical tox.ini files,
not to be modified or made unique within each charm repo.

This is to ensure consistency across charm repos in tox
target naming, approach and purpose, also giving the
charm dev and test experience additional consistency.

Also create empty dirs with .keep files where necessary.
Some classic charms have actions and/or lib dirs, and some
do not. In all classic charms, flake will now check those
dirs to ensure lint coverage of existing or future content.

All OpenStack charms are now directly published to the charm store
on landing; switch Amulet helper to resolve charms using the

be build and published prior to being consumable.

Pause failed as configure_https() had a service restart that was missed
