View Interface Data

You can view data about your network interfaces in several locations in USM. These include the Interface Group view and the device interface view. The Interface Group view displays basic metrics for the list of interfaces. The Interface view displays further metrics.

You can view data about your network interfaces in several locations in USM. These include the Interface Group view and the device interface view. The Interface Group view displays basic metrics for the list of interfaces. The Interface view displays further metrics.

Make sure that you have configured the required probes to view interface metrics. See the article USM Prerequisites for more information.
The Interface Group View
Click an Interfaces group name in the USM tree view to open the Interface Group View. This view allows you to:
  • See a list of all interfaces on a network device, including important attributes and metrics:
    • Utilization % in/out
    • Errors % in/out
    • Discards % in/out
    • MAC address
    • Device Speed
  • Sort the interfaces on any column.
  • Select an interface and see a detailed view of interface attributes and metrics.
Columns for administrative data in existing interface groups are hidden if they do not contain data. Columns for metrics are displayed whether data is returned or not. All columns are displayed in the dialog for creating a new interface group.
Columns in the Interfaces tab allow for quadruple sorting on metrics. For example:
  • Click the
    Utilization %
    column once to view
    Utilization % (In)
    in ascending order.
  • Click the
    Utilization %
    column again to sort on
    Utilization % (In)
    in descending order.
  • Click the
    Utilization %
    column again to change the sorting to
    Utilization % (Out)
    in ascending order.
  • Click the
    Utilization %
    column again to change the sorting to
    Utilization % (Out)
    in descending order.
Interface report graphs distinguish between alarms that return no data, alarms that return metric values of 0, and alarms that return metric values of less than 1. A gray cell after the interface name indicates that no metrics are available; an empty (white) cell indicates that the returned metric value is 0; and a graph that occupies at least one pixel indicates that there is returned data, however small. Hovering over a cell displays the values for that metric.
 
To view information about an interface in the table, sort on the column of interest and select an interface. The
Interface
view opens and displays information and tabs to view alarms and select further metrics.
The
Interface
view can also be opened from the USM tree view and from the
Interfaces
tab in a device view. Information in the
Device Interfaces
view is identical to the information in the
Interface Group
view.
The Device Interfaces View
To view information on interfaces in the context of a device, open a Device View and select the
Interfaces
tab. 
Follow these steps:
  1. Expand a group in the USM tree view.
  2. Select a computer system.
  3. Click the
    Interfaces
    tab at the top of the window.
Information in the
Device Interfaces
view is identical to the information in the
Interfaces Group
view table. Columns for administrative data are hidden if they do not contain data. Columns for metrics are displayed whether data is returned or not.
The Interface View
The Interface view is available when you select an interface from an interfaces table or the USM tree view. The view contains information available in the table views and tabs to view further metrics.
Follow these steps:
  1. Expand a group in the USM tree view.
  2. Select a computer system.
  3. Navigate to the
    Interface
    tab using one of the following methods:
    • Click the
      Interface
      tab at the top of the
      Device View
      screen. A list of available interfaces for the device appears. Select an interface from the table.
    • Select an interface from the USM left navigation tree. Interfaces are indicated with the interface (Interface Icon ) icon.
  4. Click the interface that you want to view.
The Details and Metrics tabs display line charts with intervalized data to the right. If there are multiple data samples for an interval, the values are averaged. Minimum and maximum values for the sampled data is displayed as a shaded area below and above the averaged value. To view another interval or change chart display properties, hover over the upper right area of a chart and select the pop out icon (Pop Out Icon); this loads the chart into another browser window as a Performance Report.
The Metrics Tab
The
Metrics
tab allows you to display metrics that have been configured for the interface.
Follow these steps:
  1. Expand the metrics menu.
  2. Select a metric or set of metrics.
The metrics are displayed in the pane to the right.
Data charts in the Metrics view are the same as for the interface details view.
The Advanced Tab
The
Advanced
tab displays graphs for the following SNMPcollector probe metrics:
  • Utilization In (%)
  • Utilization Out (%)
Interface utilization percentage takes into account the overridden speed configured in SNMPcollector (for example: 50 Mpbs Down/10 Mbps UP).
Contents of the
Advanced
view changes based on configured metrics. For example, if CA Network Flow Analysis (NFA) has been integrated with UIM, NFA data is displayed in this view with a link to the NFA diagnostic view for the interface. Refer to system configuration details for metrics available to this view.
