Connectivity and I/O Performance Monitoring

Foglight for Storage Management provides comprehensive topology views which detail all I/O paths and components on each I/O path from VMs down to their assigned physical storage devices. These views assist in determining where actual performance or connectivity problems are occurring during I/O requests, something which is not possible using traditional virtual infrastructure management tools. For more information, see Assessing Connectivity and I/O Performance.

Description
Navigation Panel

Contains a menu of all the dashboards that you can access based on your role. Select a dashboard to view in the display area. The panel operates like a drawer and can be open or closed using the arrow.

Display Area

Displays the contents of the selected dashboard.

Action Panel

Provides the following functions:

•
Lists the actions that you can perform on the current dashboard.
•
Lists the views and data that you can add to a new dashboard or report.
•
Provides access to context-sensitive help and the online help system.

The panel operates like a drawer and can be open or closed.

Breadcrumbs

Displays the path of dashboards you navigated to get to the current dashboard. Click a name in the path to return to that dashboard.

NOTE: The browser Back button is disabled. Use the breadcrumbs to return to the previous screen.
Time Range

Controls the time period for the data displayed in the dashboard and any drill-down views you access. The default is the last four hours. Click the text to open the time range popup and set the range.

Sparkline

Shows the trend of a metric in a small space. The value beside the sparkline is the current value for the metric in the selected time range. When used in a table, sparklines provide an easy way to compare spikes or other trends in a group of metrics. Click a sparkline to plot all data points for the time period on a graph.

NOTE: If the last collection failed for any reason, the sparkline value is n/a.
Status Icons

Displays the status of a storage resource. For more information, see Understanding Status, Alarms, and Rules in Foglight for Storage Management.

Introducing the Storage Monitoring Architecture

Foglight for Storage Management provides complete monitoring of virtual storage environments, providing performance and capacity management metrics. It is designed for customers requiring storage monitoring functionality, but not full-fledged virtualization environment monitoring functionality.

Foglight for Storage Management monitors virtual environments, providing performance and capacity management metrics to assist you in:

•
Improving management of virtual environments from host to storage.
•
Gaining the information required to optimize storage performance associated with your virtual server environment.
•
Ensuring service level agreements are met.
•
Maintaining high levels of customer satisfaction.
•
Avoiding the loss of cost savings already achieved with virtualization.

Foglight for Storage Management gathers extensive performance metrics and presents that data in a graphical interface using architectural diagrams, graphs, alerts, and drill-down screens to quickly identify virtual and physical storage problems. It fully supports VMware (vCenter and vSphere) and Hyper-V environments, allowing you to browse through your virtual infrastructure to identify storage performance, capacity, or topology issues.
