Foglight for VMware 5.6.16 - User and Reference Guide

The blue area on the graphs represents current consumption or activity on the target ESX Host. The orange area specifies projected worst case consumption or activity. The red dotted line specifies the target ESX Host capacity with respect to the corresponding metric. For reference information about the data appearing on this dashboard, see VMware Modeler Views .

When using the VMware Modeler dashboard, you should extend the time range in order to better assess the long term impact of the potential migration. For specific information about adjusting dashboard time ranges, refer to the Foglight for VMware User Guide.

OS mapping involves associating various versions and editions of a particular operating system with a common OS name. You configure OS mapping rules using the Administration tab on the VMware Environment dashboard. This helps Foglight for VMware map the OS names reported by Foglight for VMware to those reported by physical OS monitoring, so that you can view all Windows machines, all Linux machines, and so on.

For reference information about this view, see OS Mapping view .

Foglight collects data from monitored environments and creates a data model in real-time. The resulting topology model consists of nodes where each node is an object instance of a particular object type. Each type of monitoring environment can have a unique set of object types. Foglight for VMware includes a set of topology object types and their definitions. When Foglight collects data from your VMware environment, it builds the topology model that consists of the instances of the object types defined by Foglight for VMware. By default, a monitored environment can result in up to 50,000 object instances being created by a single object type. This value is controlled by the foglight.limit.instances registry variable.

Explore the Instances and Limits view to see the existing VMware object types. To access this view, on the VMware Environment dashboard, open the Administration tab, and click Review Instances and Limits.

The Instances and Limits view displays the list of the existing VMware object types, and for each type it shows the type name, instance limit, instance count, instance limit utilization, and the current status given as a highest severity level associated with an instance of that type. This information can give you insight into the size of your database and whether additional adjustments are required to improve your system performance. For example, if an object type results in a high number of object instances, this may result in performance bottlenecks. To prevent them, check if any of these are updated recently and, if not, delete them from the database.

To view the list of existing registry variables or to edit them, click Edit Registry Variable in the top-left corner. For complete information about registry variables, see the Administration and Configuration Help.

In an IT environment with a high number of physical and virtual machines, it is often important to determine the true cost of virtual machines in order to adequately plan resources for system utilization. The Chargeback tab available on the VMware Environment dashboard provides standard models, allowing you to get insight into host machine usage within a data center.

For complete information about this tab, see the Managing Chargeback User Guide.
