The application page provides complete visibility of a single application in vRealize Network Insight Cloud. This enables you to troubleshoot problems and also view the analytics.

To view the details of any application, from the navigation pane, go to Plan & Assess > Applications 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, 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-T Data Center) 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
  • New and unprotected members
  • External accessed services
  • Internet accessed services
  • Used application ports
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.
  • 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

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 uuper-right corner of the topology map to either pin this topology map to an existing pinboard, or create a pinboard.

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.
