As announced in our last blogpost about the official release of Cyclops 2.0, which is finally out and is adding new features. The collector that is being released today is the Ceilometer Usage Collector. This collector enables Cyclops 2.0 to provide full rating, charging and billing support to an OpenStack deployment using the data provided by Ceilometer. In addition […]
Ceilometer can collect a large amount of data, particularly in a system with large amount of servers and high activity: in such a scenario, the numbers of meters and samples can be large which affects ceilometer performance and gives rise to quite large databases. In our particular case we are studying energy consumption in servers […]
In our previous blog post we showed a web application to monitor and understand energy consumption in an Openstack cluster; the main goal of this tool is to understand how energy consumption relates to activity on the cloud resources. In general, this can be quite complex as there are many resources to take in account […]
In one of our projects we need to understand the energy consumption of our servers. Our initial work in this direction involved collecting energy consumption data using Kwapi and storing it in Ceilometer for further study. The data stored in Ceilometer is valuable; however, it is insufficient to really understand energy consumption in detail. Consequently, […]
In one of our earlier blog posts, we described some test we performed to determine how server power consumption increases with compute load; this post is something of a variation on that post, but here we put the focus on work taking place within VMs rather than work taking place within the host OS. The […]
In some of our projects we need to understand the energy consumption of our servers in an Openstack cluster. The first step in this process was to collect energy consumption data from our IBM servers; we stored this in Ceilometer for further study. In this blog post we will cover how we do this. First, […]
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 […]
Introduction The Ceilometer project is a core OpenStack service that provide collection of metering data on managed virtual resources (e.g. compute, storage, networking). Before it was only possible to collect data from OpenStack virtual resources which are running upon an OpenStack deployment. The work presented hereafter addresses this issue outlines a means to monitor both virtual […]
From “Icehouse” release on Openstack has been added monitoring physical devices. At this moment available only one inspector – SNMP Inspector. IPMI Inspector will be add soon. Schlagwörter: Ceilometer, CodeContribution, openstack, Tutorial
