VMware vROps - Oversized VMs Dashboard

Oversized VMs in a virtualized environment lead to wasted resources and lower consolidation ratios. This also introduces performance problems such as CPU Contention and Ready as the workload utilization increases. The Oversized VMs Dashboard will help you find and analyze VM candidates that could be down-sized and enable your organization to get more with less. The goal of this dashboard is to empower virtualization admins to find over-sized VMs, analyze their historical resource utilization, provide sizing recommendations, and back it up with evidence in order to reclaim unused resources.

I know what you're going to say: "easier said than done." Yes, the battle to reclaim resources is mostly a lost one already unless you can educate your users upfront and prevent over-sizing to begin with. If you still want to endeavor on that journey, then I highly recommend you read a VMware White Paper entitled VM Right-Sizing Best Practices Guide by VMware's Jason Garudreau. In it you will not only find very sound logic for right-sizing but also sample emails, and when combined with the evidence from this dashboard, you should be well armed and prepared to go to battle against your VM freeloaders. If nothing else, at least you will have a bad ass dashboard you can lament over how bad things really are.

VMware vROps - Application VMs Performance Dashboard

The Application VMs Performance Dashboard is an example that could be used to empower application owners/analysts to monitor their own VMs and the infrastructure hosting them. Your initial instinct maybe "why would I ever let those people see my environment!?!" Stop and think about it for a minute. You could get "those people" off your back and focus on more important things. Being transparent and offering a bit of education will go a long way in gaining trust and respect. More importantly, this is a great way of preventing finger-pointing among infrastructure and application teams during escalations. By providing environment visibility this dashboard shifts the conversation from "virtualization sucks" to solving the real issues causing poor application performance or other problems virtualization gets blamed for.

VMware vROps - vSphere Cluster Capacity and Performance Dashboard Part 2 - Top Offenders

As promised in part 1 of the VMware vROps - vSphere Cluster Capacity and Performance Dashboard post, here is part 2. In this post, I'll cover a set of three Top Offenders dashboards that allow you to find the objects (VMs, Hosts, Datastores) behind some of the values, like Highest VM CPU Ready %, in your cluster. As discussed in the last post, this is accomplished via the Dashboard Navigation feature introduced in vROps. In essence, this functionality combined with the three Top Offenders dashboards supplants the drill-in limitation of the Scoreboard widget and Super Metrics I mentioned in the previous post.
