Virtual CPU (VCPU)
Virtual CPU (VCPU) (also known as Virtual Processor) is a measure of the CPU resources on a VM. VCPU is typically expressed in a VM as the number of cores. Turbonomic measures allocated VCPU capacity and utilized VCPU in hertz of processing power (GHz or MHz).
For on-prem environments, VCPU capacity is a percentage of the CPU capacity of the underlying host (see CPU).
For cloud VMs, the VCPU capacity is determined by the instance type and the CPU options you specify upon instance launch. For example, an Azure Standard_D2_v2 instance has a default of two VCPU cores. Turbonomic discovers the VCPU capacity and expresses it as GHz of processing power.
Virtual Desktop Infrastructure (VDI)
Virtual Desktop Infrastructure (VDI) is a technology that allows virtual machines to provide and manage virtual desktops. VDI hosts desktop environments on a centralized server and deploys them to end users on request.
Turbonomic integrates with Horizon VDI so customers can apply our Application Resource Management to maximize the value of their VDI deployment.
Virtual Machine (VM)
A Virtual Machine (VM) is a software emulation of a physical computer that can run programs or applications. For an on-prem environment, one or more VMs can run as guests on a single physical machine.
For a public cloud environment, virtual machines run in cloud regions. Each VM is a unique machine with its own CPU, memory, network, and storage resources, as well as its own OS.
Turbonomic can discover and manage VMs that run in on-prem and public cloud environments.
For Kubernetes environments, Turbonomic discovers the nodes that provide resources to containers, and presents them as virtual machines in the supply chain.
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
VStorage is the allocated virtual storage capacity, measured in Kbytes.
Charts show the percentage of storage that is in use.
