Quick Update: Monitoring VMware Migrations

A lot of buzz in the information technology (IT) world has been created by Gartner’s APM model, published back in August of 2012. IT Centralization recently published an article composed by LarryDragich, which prioritized the APM framework and allowed those who are in the market for an APM (application performance management) solution the ability to see the dimensions, focus and potential benefits* associated with application performance management. Today we’d like to quickly discuss how one can monitoring VMware’s vMotion when performing a live migration in vShpere, an important aspect we found in an APM solution.
One of the most important aspects we found in this article relates around the end user experience* and coincidentally, live migration. Heroix couldn’t agree more, as end user experience was one of the primary priorities when selecting an APM solution. In fact, the article state that 80% of the APM value comes from “application visibility for the business and helps lay the foundation for performance trending and predictive analysis.”* Having the ability to predict these trends is an important one, as it allows for (but is not limited to): capacity planning, trend analysis for migration and disaster recover (DR) systems as well as proactive resource allocation.
VMware’s vMotion: Having the ability to be proactive when addressing upcoming issues is massive, especially if addressing capabilities as vSphere’s vMotion, where reporting on a resource move after it has occurred and then correlating the data with the virtual machine resources and application performance come into play. From there, the proper APM can be administered.
A monitoring solution should have the ability to play out a scenario in advance, allowing the end user visibility into what could happen if resources were moved from one host to another. It should also include a capable reporting capability, including historical usage and context. This would allow the end user to see where and when resources were affected after a migration or DR failover.
Having the ability to take the metrics which are important for IT departments: CPU capacity, memory, disk, workloads, etc. and then quantifying them into value for an organization is imperative. This is what an APM solution does, and which is why it can ease many woes of the IT professional’s world.
