Real Time Visualization (RTEV) feature facilitates real-time event rendering within a user interface (UI) environment. This feature allows for the smooth integration of real-time events directly into the UI, ultimately enhancing the user experience and delivering the most up-to-date information in real-time. RTEV supported features provide the current data in 10 seconds when the change happens which otherwise takes 5 minutes to get updated via the regular pipeline.
Real-time values are shown to the right of the vertical bar. Historical values (past 2 hours) are shown to the left of the bar and may have larger gaps between data points.
Click View All to see the switch view for all modules installed. Click these links in the Switch View to get additional information:

Guidelines and limitations for switches
These guidelines and limitations apply when using the Real Time Visualization (RTEV) feature:
-
Controller events are not in real-time and RTEV is limited to switches only.
-
Only 10 sessions per pod can have real-time data for physical and virtual deployment profiles. If there are more than 10 sessions then the data will be sent through the regular pipeline. All other deployment profiles support 20 sessions.
-
For the real-time connection to be established, you must enable the NX-API feature in NDFC and in Cisco NX-OS sites that do not have a controller.
-
On Cisco NX-OS switches, you must set the DME load interval to 10, which you can do using the following command:
hardware profile dme load-interval 10
These guidelines and limitations apply when viewing hardware resources:
-
All parameters are updated in real-time based on the cadence from the switch when it sends the data.
Interfaces
Supported Interface Types (Real time visualization)
-
Physical Interface: To view the interface details of the node such as,node name, physical interface name, operational status, and admin state. The page also displays protocols, QoS, and DOM properties of the physical interface.
-
Port Channel Interface: The port channel is an aggregate of physical interfaces and they can be statistically channeled or can be dynamic using LACP protocols. The statistical data that collects the counters for packets, bytes and various errors are similar to that of physical interface. The 150 sourcename differentiates the physical interface from port-channel (aggregated interfaces). The operational data is obtained by looking at an additional set of objects that gives the admin-status, oper-status and list of member interfaces for both PC and vPC.
-
vPC Interface: The vPC is a logical interface that spans across two physical switches for fault tolerance. For a vPC interface type, the Logical Neighbors information is also displayed. The categories that are supported are L3Out, IPN, ISN, L4-L7.
-
SVI Interface: An SVI is a virtual routed interface that connects a VLAN on the device to the Layer 3 router engine on the same device. Specific information such as Member Interfaces over which the SVI is deployed, VLAN ID, VLAN Type, Encap VLAN are displayed for the SVI interface.
Click an interface to view more details about it.

The Anomaly level shows the total number of anomalies that have occurred and the number of anomalies that have occurred in the last week.
Hover over the Anomaly Level to view the category of the anomalies occurred. Click the Anomaly Level to get specific information on the anomalies present for the specific controller or switch.
The View all anomalies takes you to the Anomalies tab. See Anomalies to understand how to navigate across the anomalies.
Filtering Information
In some cases, you might be able to filter results to find information more easily.
For example, you might have a situation where there a large number of endpoints under a single leaf switch, but you are only interested in endpoints that have a certain VLAN value.
You could filter the information to show only those specific endpoints in this situation.
Use the following operators for the filter refinement:
| Operator | Description |
|---|---|
|
== |
With the initial filter type, this operator, and a subsequent value, returns an exact match. |
|
!= |
With the initial filter type, this operator, and a subsequent value, returns all that do not have the same value. |
|
contains |
With the initial filter type, this operator, and a subsequent value, returns all that contain the value. |
|
!contains |
With the initial filter type, this operator, and a subsequent value, returns all that do not contain the value. |
|
< |
With the initial filter type, this operator, and a subsequent value, returns a match less than the value. |
|
< = |
With the initial filter type, this operator, and a subsequent value, returns a match less than or equal to the value. |
|
> |
With the initial filter type, this operator, and a subsequent value, returns a match greater than the value. |
|
> = |
With the initial filter type, this operator, and a subsequent value, returns a match greater than or equal to the value. |
