Dell Foglight for Virtualization Enterprise Edition, formerly known as vFoglight, is a virtualization management and monitoring tool that allows administrators greater control over VMware and Microsoft Hyper-V virtual environments. Foglight supports VMware VirtualCenter (VCMS) 2.5.x, vCenter Server 5.5, vSphere up to version 6, and vCloud 5.5 and View 5.5. It also supports Hyper-V environments running on Microsoft Windows 2008 Server R2 or Windows 2012. Foglight features visualization, optimization, automation and capacity planning. It also has vSwitch support, chargeback management and Virtual Desktop Infrastructure (VDI) monitoring. Dell Foglight for Virtualization requires an existing Foglight Management Server, which is a hardware unit sold separately by Dell.
Foglight's dashboards provide a single pane of glass view into heterogeneous virtual environments, allowing administrators to monitor multiple different hypervisors from one central console. The monitoring unit also features asset tracking, alerting administrators to virtual machine (VM) migrations from one physical host to another. Dell Foglight for Virtualization monitors and wide displays a range of information including storage utilization, memory usage, CPU performance, disk inputs/outputs (I/O), and network I/O to identify performance issues. It will also monitor Microsoft Active Directory and Exchange for availability issues.
The Foglight optimization unit has a right-sizing feature which prevents over- and under-provisioning: the Wastefinder tool locates abandoned, powered off, and zombie VMs, as well as unused templates and snapshots. The Resource Reclamation tool then returns these resources back to the pool.
The automation unit allows administrators to deploy new VMs into an environment, decommission unwanted VMs and remove obsolete VM files. Foglight also allows automated workflows, VM administrative actions, and root cause analysis to be launched in response to service alerts.
The capacity planning and resource management element allows scenario modeling and performs impact analysis for migration of VMs from one host to another. It also charts workload density and cluster-based capacity utilization to ensure that VMs are not deployed on hosts close to their capacity thresholds. The resource management unit uses historical usage trends to forecast future consumption. Finally, Foglight allows users to auto-deploy VMs into reserved slots based on resource usage.
Foglight comes with additional features such as chargeback and showback reporting, VDI monitoring and service-level agreement (SLA) management. The VDI monitoring feature allows administrators to monitor performance for end-user client machines, storage pools, and ESX servers.
Dell Foglight for Virtualization as a complex pricing and prerequisite structure, though it is available for a 45-day free trial. It requires an existing Foglight Management Server, which is a separate hardware unit. Additionally, Foglight is customized to the environment using a sizing exercise, which determines the pricing and licensing structure offered, starting at $799 per socket. However, a 1-CPU socket license version is available on CDW.com for $683.99.
