The complexity of a typical OpenNebula installation brings a special set of challenges on the monitoring side. In this talk, I will show monitoring of a full stack of from the physical servers to storage layer and ONE daemon. Providing an aggregated view of this information allows you see the real impact of a certain failure. I would like to also present a use case for a “closed-loop” setup where new VMs are automatically added to the monitoring without human intervention, allowing for an efficient approach to monitoring the services a OpenNebula setup provides.
I’ve been into virtualization and storage for a long time and I like the amount of abstraction OpenNebula offers. Professionally I have been a Unix systems administrator for most of my working life. I’ve also done systems integration and monitoring work on the Check_MK project. Now I’m one of very few Nagios experts in Germany that aren’t working for one of the 3-5 leading Nagios outfits and as such I’m able to speak freely about what I think works best for the users. My strength is simply sitting down and listening to what people really need.
