The application page provides a complete visibility of an application in VMware Aria Operations for Networks. The application page also allows you to troubleshoot problems and view analytics.

To view the details of an application, from the navigation pane, go to Applications > List and select an application from the list.

The following table describes different components of the application page:

Component Description
Overview You see the overview of the application which includes:
  • The application summary which provides information about alerts, incoming and outgoing traffic, flows, intents associated with the application, countries associated with the application, VMs, physical IPs, Kubernetes services counts, and so on.
  • The Application Topology which displays the end-to-end interactive topology map of your application. For more information, see Application Topology Map.
  • Alerts related to the application.
  • Application Members Manager which manages entities (such as VMware vCenter and NSX) for all application members.
What's New
  • You see what's new in the last 24 hours which includes:
    • Incoming and outgoing traffic count
    • Dropped flows
    • Analytics alerts
    • New members
    • New unprotected members
  • External services accessed by the application in the last 24 hours.
  • Services accessed by the application using the internet in the last 24 hours.
  • Application ports used in the last 24 hours.
Metric You see the following metrics:
  • VM metric information that represents network rate, CPU, memory, and disk information.
  • Kubernetes metrics
Flows You see the following traffic flows or flow analytics associated with the application in the last 24 hours:
  • Top talkers by flows
  • Top application flows by rule
  • Top incoming traffic by App-Id
  • Top outgoing traffic by App-Id
Microsegmentation You see:
  • Contextual flows between entities, which provides data of different flow types such as all allowed and dropped flows, protected and unprotected flows by NSX Distributed Firewall.
  • What's new in the last 24 hours
Intents You see the following options from the drop-down menu:
  • Intent Definitions: Displays the metrics that are monitored to verify whether the conditions defined in the intents are met for the application.
  • Intent Violations: Displays the intent violation alerts associated with the application.

To start a troubleshooting incident from the application page, click the Troubleshoot button on the top right corner of the application dashboard.

Click More Options next to the Troubleshoot button to modify the application or export to PDF.

Application Topology Map

The application topology map shows the traffic or the flows between the tiers of the same application and between applications. It displays:

  • Tier overview
  • List of members of the application (VMs, Kubernetes services, and physical IPs).
  • Flows between tiers, internet, and shared services.
  • The physical IPs that the application depends on or uses.
  • Shared services
  • Other applications with which this application talks to.
  • List of load balancers in the application.
Application Topology

In the application topology map, hexagons represent tiers, load balancers, switches, shared services, and other network entities. You can hover over the hexagon and click View Details to view the details of that network entity.

The thin lines that run between two hexagons represent the flows between those two network entities. You can click anywhere on the flow to view details such as service endpoints of the flows, total traffic of the flow, and so on.

Similarly, if the virtual machines of a tier are configured behind one or more load balancers, you can select the thick lines that runs between the load balancer hexagon and the tier hexagon to view the details of virtual services, pools, and flows that are shared between that tier and the load balancers.

You can click the Pin widget icon at the upper-right corner of the topology map to either pin this topology map to an existing dashboard, or create a dashboard.

You can use the filter and the zoom options at the lower-right corner of the topology map to:

  • View all flows, unprotected flows, or only degraded flows in the topology.
  • Show or hide the switches associated with the application.
  • Show or hide the load balancers associated with the application.
  • Zoom in or zoom out of map
  • Rearrange the map to fit the current screen

  • Show or hide the legend which indicates the representation of each icon in the application topology.
