Future Saturation page in the vSphere Virtual Machines view

Use the Future Saturation page in the vSphere Virtual Machines view to get a quick view of the vSphere virtual machines that have exhausted or exhausting resources (CPU, memory, storage) within the next 30 days.

To access the page, in the navigation pane of the Views tab, click Views > Virtualization > vSphere > Virtual Machines, and in the vSphere Virtual Machines page, click the Future Saturation tab.

VMs exhausting capacity table

The VMs exhausting capacity table displays the capacity status of VMs, daily trends, and the estimated number of days to saturation. Each row in the table corresponds to a VM and displays the following metrics:

¹ For the virtual machines, if the virtual node (with namespace as opt:meas:vn) data is available, the memory data computation also considers the virtual node memory data.

For more information about the Days to Saturation and other indicator parameters used for metric computations in this view, see Indicators.

Detailed information about a particular VM

To view the details page for a specific VM, click its name under the VM column. You can use the sorting and filtering options on the page to find a specific cluster.

The VM details page displays information for the selected VM under the following sections or panels:

Section or Panel	Description
Summary page	A quick graphical summary of the CPU and memory utilization, and network bit rate and disk transfer rate for the VM. Core metrics for the selected entity are displayed as analysis charts, depending on available data. At the bottom of each chart is a link that takes you to the Data Explorer view for the specific resource type, and displays charts and information for a larger set of metrics. The data displayed in Data Explorer view charts for any resource part of this view category, is based on the time filter that is applied to the primary view in this tab. You can select other time filter options to view charts over a different time resolution For more information, see Virtual Machine page in the vSphere Data Explorer view.
Configuration Details page	Configuration information about the cluster.
Related Information panel	Displays the following links: Thresholds: Clicking on this link takes you to the Metric thresholds page for the selected entity in the Workspace. This page lists the metric thresholds and enables you to edit or delete them or add new thresholds. With thresholds, you can monitor how the metric is behaving relative to a specified value. Virtual node: Clicking on this link takes you to the Virtual node details page for the selected entity and displays the metrics with namespace as opt:meas:vn. This link is enabled when the administrator has collected the virtual node data: Install a Capacity Agent inside the VM from which you want to collect metrics. Configure the Gateway Server and Capacity Agent to initiate data collection. Configure and use the out-of-the-box BMC-TrueSight-Capacity-Optimization-Gateway-VIS-files-parser to collect the required metrics from the VM.
Recommendations panel	All available recommendations for the VM. For more information, see Recommendations-page-in-the-vSphere-Virtual-Machines-view. If the virtual node data is available, the forecasted saturation for memory is computed based on the virtual node memory utilization. Otherwise, it is computed using MEM_ACTIVE of the virtual machine. When using MEM_ACTIVE, the vSphere VM Active Memory increase factor is applied to increase the MEM_ACTIVE metric value. You can configure the value of this vSphere VM Active Memory increase factor. For details, see Configuring-and-managing-thresholds-for-metrics-and-indicators.
Tags panel	List of tags that are associated with the VM. You can assign or remove tags by using the Edit Tags option from the Tags action menu.

Detailed information about a particular virtual node

To view the details page for a specific virtual node, click the Virtual node link in the Related Information panel of the VM details page. This link is displayed if the the virtual node data is available.

Section or Panel	Description
Summary page	A quick graphical summary of the CPU, Memory, Real Memory, and Total File System Utilization for the virtual node. Core metrics with namespace as opt:meas:vn for the selected entity are displayed as analysis charts, depending on available data.
Configuration Details page	Configuration information about the virtual node.
Related Information panel	Displays the Thresholds link. Clicking on this link takes you to the Metric thresholds page for the selected entity in the Workspace. This page lists the metric thresholds and enables you to edit or delete them or add new thresholds. With thresholds, you can monitor how the metric is behaving relative to a specified value.
Recommendations panel	All available recommendations for the virtual node. For more information, see Recommendations-page-in-the-vSphere-Virtual-Machines-view. For the virtual node data, the forecasted saturation for memory is computed based on the virtual node memory utilization. Otherwise, it is computed using MEM_ACTIVE of the virtual machine. When using MEM_ACTIVE, the vSphere VM Active Memory increase factor is applied to increase the MEM_ACTIVE metric value. You can configure the value of this vSphere VM Active Memory increase factor.
