The changing face of performance management for virtual infrastructures

Srinivas Ramanathan, CEO, eG Innovations Inc. | Nov. 6, 2013
Isolating the exact cause of a problem is often the biggest challenge in a virtual environment, and it is not enough to simply monitor the hypervisor. You have to take a more holistic view.

Further complicating the situation is the fact that dependencies are dynamic in a virtual infrastructure. With vMotion, a VM and the applications running on it can move dynamically from one physical machine to another. So in one instance applications one and two are contending for resources, while in another, applications two, three and four are sharing resources. Virtualization performance management systems have to be able to handle such dynamic dependencies.

In conclusion, the process of problem solving using a fragmented set of monitoring tools is slow and manual and at times frustrating. Problem solving requires expertise because the dots have to be connected manually. You receive a great deal of metrics on a daily basis and time has to be spent determining what the metrics mean.In a dynamic virtual infrastructure where dependencies change in real time, a slow and manual process isn't able to handle the variety of considerations needed to really understand root cause problems. To really do justice to performance management monitoring IT needs to move away from merely collecting metrics for manual interpretation. Virtualization dynamics and dependencies can cause significant performance and user experience issues that diminish the benefits of virtualization and risk disruption of critical business processes.
