Virtual Memory (VMem)

Virtual Memory (VMem) is a measure of the memory resources on a VM. Turbonomic measures allocated VMem capacity and utilized VMem in bytes (GB or MB).

Note that percentages of allocated VMem are measured against whichever is the less of the VMem limit (if set) or the allocated VMem capacity. This is also true in reports and recommended actions. For example, assume a VM with allocated VMem of 8 GB, but a limit of 4 GB. In this case, the percentage in a chart shows the percentage utilized of 4GB.

For on-prem environments, VMem capacity is a percentage of the Mem capacity
of the underlying host (see Mem). For cloud VMs, the VMem capacity is determined by the instance type. 

Virtual Processor


VStorage is the allocated virtual storage capacity, measured in Kbytes. 

Charts show the percentage of storage that is in use.


Wasted Storage

[Also called Ghost Volumes] Wasted Storage refers to storage volumes that are not actively used by any workload in the system. Typically, these are paid for but unused.

Turbonomic can help you reclaim unused storage or realize potential savings by identifying and deleting these volumes.

Windows Management Instrumentation (WMI)

Windows Management Instrumentation (WMI) is a Microsoft-provided service which runs in the Guest OS of a VM. Turbonomic uses it to understand which applications are running on Windows computing systems, and to understand their resource consumption.

(6.4 version family, only) Turbonomic uses WMI to create and name application instances, stitch the named instances to the given VM, and feed per-application resource consumption to Turbonomic.

Workload Controller

A Workload Controller is the Turbonomic Supply Chain entity that represents a Kubernetes controller. This entity watches the state of your Container Pod entities and then requests changes where needed. You can execute container resize actions when you set the scope to a Workload Controller.

A Workload Controller executes container actions, but Turbonomic does not recommend actions to perform on the Workload Controller itself. When you scope to a Workload Controller and view the actions list, the actions apply to containers.



Zookeeper is a component of the Turbonomic platform that runs the Zookeeper software to manage the Kafka configuration settings. It is open-source software developed by Apache.
