We are using ceilometer to collect data energy from our servers. As noted previously we were having some performance issues and we needed to investigate further. In this blog post we will cover our approach to performing profiling on ceilometer API to determine where the problems arose. Of course, the first step was to take […]
We are changing our ceilometer backend from mysql to mongodb in one of our experimental Openstack installations. The reason for this change is that mongo seems to deliver better ceilometer performance than mysql; further ceilometer data structures are a more natural fit with mongo (and indeed, this is largely where they came from). This can […]
We are working on upgrading some of our servers from Havana to Icehouse. One of the reasons for doing this is that the performance of Ceilometer on Havana is underwhelming. Part of the move involves moving to a mongodb backend (default in Mirantis Openstack 5.0) but we also want to keep our energy consumption data […]
We were doing some work with Ceilometer – it appears in a few of our activities – and I was trying to get up to speed with it. Playing with the python Ceilometer client proved a little more difficult then envisaged – mostly due to deficiencies in documentation. Here’s a small note on an issue […]
Bruno is an ICCLab intern who found ICCLab through the IAESTE program. He is completing his Bachelor of Computer Science at Fundação Educacional do Município de Assis (FEMA) in Assis, Brazil and is particularly excited about how technology is growing so quickly and it has become such an integral part of our daily lives, especially […]
