To determine which VMs are over provisioned on larger environments is time consuming. Such a VMs do have negative impact on overall performance of virtual infrastructure because they literally “eat” valuable resources, which could have been used better way otherwise.
What I mean that your virtual infrastructure to perform optimal way, VMs should be always in optimum state. A right size of allocated memory, CPU or disk. This is not always easy, as environments became larger, and at the end you finish by you losing little bit of a visibility.
In this case there are software tools which are designed to help. One of those is VMturbo's Operation Manager, which identifies VMs and applications which performs poorly and can take actions automatically rightsize the workloads to maximize efficiency.
There is a new PDF from VMturbo which shows the details how it works. The recommendation are shown in a report as to do actions. You're provided with right sizing recommendation for the identified VMs. The recommendations can be to reconfigure the amount of memory (up or down), vCPU, limits (if used) and can reclaim unused or underutilized resources.
By controlling your environment in the desired state, VMTurbo SDC prevents potential bottlenecks and performance degradations while increasing the utilization of the underlying infrastructure. VMTurbo SDC significantly reduces your ongoing operational costs by reducing the number of incidents you need to troubleshoot and firefight.
The paper covers in details which metrics are analyzed and show you the ways that VMturbo can take actions. The actions can be to be performed either manually (based on recommendations) or automatically. The notifications can also be sent to an external system.
