Here’s what RDO enthusiasts have been writing about in the last week:
Deploying an OpenStack undercloud/overcloud on a single server from my laptop with Ansible. by Harry Rybacki
During the summer of 2014 I worked on the OpenStack Keystone component while interning at Red Hat. Fast forward to the end of October 2015 and I once again find myself working on OpenStack for Red Hat – this time on the RDO Continuous Integration (CI) team. Since re-joining Red Hat I’ve developed a whole new level of respect not only for the wide breadth of knowledge required to work on this team but for deploying OpenStack in general.

Ceilometer Polling Performance Improvement, by Julien Danjou
During the OpenStack summit of May 2015 in Vancouver, the OpenStack Telemetry community team ran a session for operators to provide feedback. One of the main issues operators relayed was the polling that Ceilometer was running on Nova to gather instance information. It had a highly negative impact on the Nova API CPU usage, as it retrieves all the information about instances on regular intervals.

AIO RDO Liberty && several external networks VLAN provider setup by Boris Derzhavets
Post bellow is addressing the question when AIO RDO Liberty Node has to have external networks of VLAN type with predefined vlan tags.

If demo_provision was "y" , then delete router1 and created external network of VXLAN type

Red Hat Cloud Infrastructure Cited as a Leader Among Private Cloud Software Suites by Independent Research Firm by Gordon Tillmore
The Forrester report states that Red Hat “leads the evaluation with its powerful portal, top governance capabilities, and a strategy built around integration, open source, and interoperability. Rather than trying to build a custom approach for completing functions around operations, governance, or automation, Red Hat provides a very composable package by leveraging a mix of market standards and open source in addition to its own development.”

Disable "Resource Usage"-dashboard in Horizon by Matthias Runge
When using Horizon as Admin user, you probably saw the metering dashboard, also known as "Resource Usage". It internally uses Ceilometer; Ceilometer continuously collects data from configured data sources. In a cloud environment, this can quickly grow enormously. When someone visits the metering dashboard in Horizon, Ceilometer then will accumulate requested data on the fly.
