Foglight for vCloud Director 5.8.2 - User and Reference Guide

Getting Started Setting Up Monitoring Agents Investigating Resource Consumption Levels Investigating Object Dependencies Reference

Resource Utilizations view

Use this view to review the levels of CPU, network, memory, and disk utilization and overall consumption, broken into four simple views. Foglight for vCloud Director populates these values using the metrics collected by Foglight for VMware. For more information about the metrics appearing in these views, see the Managing Virtualized Environments User and Reference Guide.

The current percentage of the selected virtual machine’s CPU load, used to execute system code and user programs, based on the total CPU capacity.

The percentage of the selected virtual machine’s CPU utilization, spent on executing system code and user programs, during the selected time period.

The expected CPU utilization range, based on historical data.

The percentage of the selected virtual machine’s CPU resources that is ready to execute system code and user programs during the selected time period.

The current rate at which the selected virtual machine transfers data from and to the network.

The rate at which the selected virtual machine transfers data from and to the network during the selected time period.

The expected network utilization range based on historical data.

The current percentage of the average memory usage by the selected virtual machine, based on the total memory capacity.

The percentage of memory used by the virtual machine during the selected time period.

The expected memory utilization range based on historical data.

The current disk I/O rate for the selected virtual machine.

The rate at which the selected virtual machine transfers data from and to the disk during the selected time period.

The expected disk utilization range based on historical data.

Reviewing Frequently Asked Questions

Foglight for vCloud Director offers a collection of frequently asked questions that provide quick insight into resource utilization levels for organization and provider vDCs in your monitored system. The question mechanism is interactive, guiding you to choose a category and specify additional parameters.

You can find the available questions on the FAQts tab of the vCloud Monitoring dashboard.

Foglight for vCloud Director includes a report generation ability. This allows you to create reports using a set of predefined templates to report on the various aspects of your virtual environment. Foglight for VMware includes a collection of predefined report templates.

You can generate, copy, and edit reports using the Reports tab on the vCloud Environment dashboard, or alternatively the Reports dashboard included with the Management Server.

Figure 36. Reports tab

For more information on how to use this tab to create and manage reports, see the Managing Capacity in Virtual Environments User Guide. For complete information about the Reports dashboard, see the Foglight User Help.

The following templates are available with Foglight for VMware.

Compile a list of vCloud Director® provider and organization vDCs. For each provider and organization vDC, the list indicates if the vDC is enabled and its alarm state, the levels of used, allocated, and limited CPU, memory, and storage resources, along with a health history bar. In addition, the report shows the allocation model associated with each organization vDC.

Compile a list of vCloud provider and organization vDCs, organizations. For each provider vDC, organization vDC, and organization, the list indicates if the vDC is enabled and its alarm state, the levels of used, allocated, and limited CPU, memory, and storage resources, along with a health history bar. In addition, the report shows the allocation model associated with each organization vDC.

Investigating Object Dependencies

A typical vCloud Director® environment consists of many interrelated components. Understanding the dependencies between logical and virtual components in your monitored environment, and the levels of resources they consume, allows you to better understand resource-related issues, potentially affecting the stability of your system. This can help you predict the impact a potential outage may have on your environment, and to prevent such events, by reallocating resources where they are most needed.
