Application Visualization

Application Visualization identifies and monitors all applications contributing to the network traffic and reports on the total applications and the total bandwidth they consume over a select period. Application Visualization allows you to identify more than 3,200 applications. It displays the traffic statistics in bytes and packets.

Refer to the following topics for more detailed information on how to configure the application and view the statistics:

Configure Application Visualization for Virtual Environment

Application Visualization can be configured in the Edit Monitoring Session Canvas Page. To add an Application Visualization application to the canvas, follow the steps given below:

  1. Drag and drop Application Visualization from APPLICATIONS to the graphical workspace.
  2. Click the Application Visualization application and select Details. The Application quick view appears.
  3. In the Application quick view, enter or select the following details:

    Parameter

    Description

    Name

    Enter a name for the application.

    Description

    Enter the description.

    Export Interval

    The time interval in seconds at which the export must be done. The export interval is set to 300 seconds. It cannot be modified.

    Advanced Settings

    Number of Flows

    The number of flows supported by the application.
    Refer to the following table for the maximum number of flows supported for VMware, AWS, Nutanix, and Azure platforms.

      Cloud Platform

    Instance Size

    Maximum Number of Flows

    VMware

    Large (8 vCPU and 16GB RAM)

    200k

    AWS

    AMD - Large (c5n.2xlarge)

    300k

    AMD - Medium (t3a.xlarge)

    100k

    ARM - Large (c7gn.2xlarge)

    100k

    ARM - Medium (m7g.xlarge)200k

    Azure

    Large (Standard_D8s_V4)

    500k

    Medium (Standard_D4s_v4)

    100k

    Nutanix

    Large (8 vCPU and 16GB RAM)

    200k

    ■  Medium Form Factor is supported for VMware ESXi only when secure tunnels option is disabled. The maximum Number of Flows for VMware ESXi when using a medium Form Factor is 50k..
    ■  If the rate of unique UDP sessions per second exceeds the threshold—calculated as maximum number of flows per second divided by the UDP timeout value—the system may fail to classify applications correctly. In such cases, AFI may not filter packets accurately, resulting in incorrect packet passes or drops. However, this limitation does not apply to DNS flows.

    Monitoring

    You can use this option, enable or disable the Application Visualization application functionality.

    Fast Mode

    Enable the Fast Mode option for performance (less CPU cycles and less memory utilization) improvement. When the Fast Mode is enabled, some or all of the attributes of the applications will be disabled. If all the attributes of the application are disabled then the application itself is disabled. Refer to Application Intelligence Sessionsection for more information on the benefits and limitations of the Fast Mode.

    Note: This option is disabled for NetVUE Base Bundle License.

  4. Click Save.

Configure Filtering and Metadata Export for Selected Applications in Application Visualization

This section describes how to perform filtering and exporting metadata for selected applications when configuring Application Visualization. Refer to the following steps for more detailed information:

Filter Traffic for Selected Applications

  1. Click the Application Visualization application in the Monitoring Session Canvas page and select Details. The Application quick view appears.
  2. Click on STATISTICS tab.
  3. Click on the drop-down menu that displays Top 10 and select the All .
  4. Select the applications for which you want to filter traffic.

    Note:  Select the applications and their attributes for traffic filtering by layer seven applications. You can select a maximum of 64 attributes for each application.

  5. Click Actions > Filter Selected Applications. The Filter Selected Applications dialog box opens.
  6. In the Filter Selected Applications dialog box, Select the existing Application Filtering map or New Map from the Send to Map drop-down menu.
    • New Map:Select this option if you wish to create a new application filtering map, to filter the traffic from the applications.
    • Existing map: Select this option if you have already configured an application filtering map and you wish to send the traffic for filtering to that map.
  7. Under the Applications section, choose the traffic as pass or drop for the selected applications.
  8. Click Send to Map.

Note:  If the New Map option is selected from the Send to Map drop-down menu. Then, the map quick view appears. Refer to step 3, 4, 5, 6, and 7 in Configure Application Filtering Intelligence for Virtual Environmentsection for more detailed instructions on how to configure Application Filtering.

Export Metadata for Selected Applications

  1. Click the Application Visualization application and select Details. The Application quick view appears.
  2. Click on STATISTICS tab.
  3. Click on the drop-down menu that displays Top 10 and select the All .
  4. Select the applications for which you want to export metadata.

    Note:  Select the applications and their attributes for traffic filtering by layer seven applications. You can select a maximum of 64 attributes for each application.

  5. Click Actions > Export Metadata for Selected Applications. The Export Metadata for Selected Applications dialog box opens.
  6. In the Export Metadata for Selected Applications dialog box, Select the existing Application Metadata application or New Exporter from the Send to Exporter drop-down menu.
    • New Application Metadata:Select this option if you wish to create a new application metadata, to export metadata from the applications.
    • Existing Application Metadata Application: Select this option if you have already configured an Application Metadata Intelligence application and you wish to send the traffic for exporting metadata from the applications.
  7. Click Export.

Note:  If the New Application Metadata option is selected from the Send to Exporters drop-down menu. Then, the application quick view appears. Refer to steps 3 and 4 in Configure Application Metadata Intelligence for Virtual Environment sectionConfigure Application Filtering Intelligence for Virtual Environmentfor more detailed instructions on how to configure Application Metadata application.

View Application Statistics for Application Visualization

To view the application Statistics for the Application Visualization application, follow the steps given below:

  1. Click Traffic > Virtual > Orchestrated Flows > Select your cloud platform.
  2. Select a monitoring session from the list view, click Actions > Edit. The Edit Monitoring Session page appears.
  3. Click the application and select Details. The Application quick view appears.
  4. Click on STATISTICS tab.
  5. You can view the following in the statistics page:
    1. Total Traffic: Displays the total traffic of the network. Use the drop-down menus to change the parameters. You can use the Select Tags filter option to filter the traffic related to the selected application tags.
    2. Total Applications : You can view all the applications and their bandwidth in the network. You can also perform filtering and exporting metadata for selected applications. Refer to Configure Filtering and Metadata Export for Selected Applications in Application Visualization for more detailed information on how to perform filtering and exporting metadata for selected applications.
    3. Top 10 Applications: Click on the drop-down menu that displays All and select the Top 10 . Displays the Top 10 applications running in the network based on the metrics.
    4. Top 10 Application Families: You can view a graphical representation of top 10 applications running in the network based on the metrics. When you hover over the Pie-chart, GigaVUE-FM shows the application families in the network.

    You can view the statistics for past hour, past 24 hours, or past 7 days. GigaVUE-FM also allows you to view statistics for a particular period by selecting the date and time. The selected data and time must be with in the past 7 days.

    GigaVUE-FM takes more than five minutes to display the application statistics since the export interval is fixed at five minutes. For the first fifteen minutes after creating the solution, if GigaVUE‑FM receives traffic, it will show real-time data. If there is no traffic during this time, it will take at least eleven minutes to display the statistics once traffic is received.
