In one of our projects we are making contributions to an Openstack project called Watcher, this project focuses on optimizing resource utilization of a cloud according to a given strategy. As part of this work it is important to understand the resource utilization of the cloud beforehand in order to make a meaningful contribution. This requires collection of metrics from the system and processing them to understand how the system is performing. The Ceilometer project was our default choice for collecting metrics in an Openstack deployment but as work has evolved we are also exploring alternatives – specifically Monasca. In this blog post I will cover my personal experience installing Monasca (which was more challenging than expected) and how we hacked the monasca/demo docker image to connect it to our Openstack deployment.

The third day of the summit had a different feel from the previous couple of days – there was no keynote and there were noticeably less people around: there is a strong sense that the show is over and now it’s necessary to do some real work. Hence, there is more time and space allocated to the project teams to enable them to move their work forward.

GEYSER focuses on making Data Centres more energy efficient in the context of varying availability of energy. One of the tools used in this context is a mechanism to effect load consolidation on IT workload in the Data Centres. The GEYSER project has chosen to focus on the Openstack cloud computing framework as the context to perform such load consolidation and in the earlier stages of the project developed a load consolidation solution which was demonstrated on a small cluster locally.
During project execution, activities evolved within the Openstack community resulting in an opportunity for GEYSER. More specifically, the Watcher group was formed within the Openstack community to focus on making Openstack more energy efficient. Interestingly, one of the main focal points of the Watcher group was also to leverage load consolidation mechanisms to effect energy savings. Continue reading
