Procedure

  1. To discover existing applications in your environment:
      1. From the left navigation panel, go to Applications > All Applications.
      2. Click the Discover button on the top-right corner of the page.
    • Or, from the left navigation panel, go to Applications > Discover.
  2. You can discover applications in multiple ways. Select the preferred tab and perform the related steps.
    Tab Description
    Tags

    Use tag based application discovery if you have added tags for virtual machines in your VMware vCenter, Azure, AWS, or VMware VMware NSX-T environments.

    To learn more, see Discover Applications using Flows.
    ServiceNow

    Use ServiceNow based application discovery if you have mapped your applications in ServiceNow.

    To learn more, see Discover Applications using ServiceNow.
    Flows

    Use flow based application discovery if you want to discover applications by analyzing the traffic patterns and network flows in your environment.

    Flow based application discovery is automated and does not require any user input to start the discovery.

    To learn more, see Discover Applications using Flows.
    Names

    Use name based application discovery if your VMs and Kubernetes services follow a logical naming pattern.

    To leran more, see Discover Applications using Names.
    Advanced

    Use advanced application discovery if you want to discover applications using a combination of VM names, NSX-V security tags, security groups, tags from VMware vCenter, Azure, AWS, or VMware VMware NSX-T environments.

    To learn more, see Discover Applications using Advanced Properties.
