RHBA-2017:1543 - Bug Fix Advisory

Topic

Updated OpenStack Telemetry packages that resolve various issues are now
available for Red Hat OpenStack Platform 8.0 (Liberty) for RHEL 7.

Description

Red Hat OpenStack Platform provides the facilities for building a private
or public infrastructure-as-a-service (IaaS) cloud running on commonly
available physical hardware. This advisory includes packages for:

• OpenStack Telemetry service

OpenStack Telemetry (ceilometer) collects customer usage data for metering
purposes. Telemetry implements bus listener, push, and polling agents for
data collection. This data is stored in a database and presented via the
REST API. In addition, Telemetry's extensible design means it can be
optionally extended to gather customized data sets.

This update addresses the following issue:

• Previously, the ceilometer compute agent retrieved the list of instances residing on the Compute node and cached it, but when a instance was deleted the cache is not cleaned.

Consequently, the ceilometer compute agent would logs many superfluous messages about missing instances on the compute node, until it was restarted.
With this update, deleted instances are processed to update the cache accordingly.
As a result, when the cache is refreshed, the ceilometer compute agent stops logging messages about missing instances. (BZ#1390846)
