In vRealize Network Insight, you can discover applications based on flows.

Flow based application discovery uses machine learning algorithms to auto-discover your applications and application boundaries by analyzing the traffic patterns and network flows in your environment. To learn how to discover applications based on flows, see Discovering Applications Based on Flows.

Procedure

  1. From the left navigation panel, go to Applications > Discover.
  2. Select the Flows tab.

    You see all the available applications based on flows. You also see application boundaries and tier boundaries between VMs based on the network flow communication between the VMs.

  3. To modify the scope and the naming preference, click Edit Discovery.
    1. Select the naming preference and the order in which you want to name applications and tiers. To learn more, see Set up Application and Tier Naming Preference.
    2. Select the duration and the scope of application discovery. To learn more, see Modify Application Scope.
    3. Click Submit.
    Note: vRealize Network Insight recommends the use of naming preferences to create logical and meaningful names for your applications and tiers.
  4. To pause or stop the auto discovery of flows on the Discover Applications page, click the More Options icon next to Edit Discovery, and select Pause discovery or Stop discovery.
    Note:

    If you click Stop discovery, you loose all the discovered applications.

  5. Click Granularity to group the discovered applications at various levels based on number of tiers and VMs. You can select one of the following Granularity levels:

    • Coarse: The application group includes more tiers and VMs.

    • Medium: The application group includes less tiers and VMs.

    • Fine: The application group includes much fewer tiers and VMs.

    In the tabular view of discovered applications, you can see the Confidence column which describes the accuracy level of the application grouping. High confidence level indicates that the grouping accuracy is high and requires less user intervention.
