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 1 minute 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.
Controller events are not 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 via regular pipeline. All other deployment profiles support 20 sessions.
Click these links in the Switch View to get additional information:

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.

QoS
Quality of Service (QoS) in networking is a process that controls traffic to adjust the overall network traffic based on the requirements of specific applications.
Anomalies
Click to view anomaly information on this specific interface in this switch. See Anomalies for more information.
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.
Microbursts
Microbursts
Click Switches > Any switch > Connectivity > Interfaces > Any interface > Trends and Statistics to view Microbursts in Inventory.
A burst of traffic impacts the output buffer of a physical interface port given the channel is already subscribed with line-rate flows. These bursts are often hard to detect with just given queuing parameters, such as buffer cells used and buffer cells unused as there is a high variance of usage of these buffers.
The Cisco Nexus 9000 series switches provide a capability of detecting this by issuing an interrupt that is triggered when a queue occupancy rises above x bytes and falls below y bytes. You can configure up to 8 output queues per physical interface port.
To configure Microburst in Nexus Dashboard Insights, navigate to Admin > System Settings > Microburst.
See the Microburst section in Getting Started to view more details.
You can view the microbursts details such as Queue, Start Time, Number of Bursts, Max Duration, Avg. Duration, Max Peak, and Avg Peak in the Microbursts section. A chart view and a tabular view is available.
Anomalies are raised in Nexus Dashboard Insights based on the number of microbursts at the interface level. Microburst anomaly jobs run every 5 minutes in a container environment, which checks for microburst records in microburst database. If the number of microbursts per interface is greater than microburst count threshold at any given point of time, then a minor anomaly is raised per interface in a node.
Nexus Dashboard Insights raises these anomalies:
-
The flows that are displayed in the summary table are gathered from Flow Telemetry data for a corresponding egress interface. Nexus Dashboard Insights matches the egress interface and egress queue to gather the corresponding microburst.
-
Based on the percentage of threshold, microburst is either low, high, or medium. The percentage of threshold is inverse to sensitivity. When the number of microbursts are greater than 100 on a particular interface, an anomaly is raised.
-
If flow telemetry is enabled and microburst is also enabled, then Nexus Dashboard Insights displays the estimated impact of flows for a particular microburst anomaly.
-
If the flow telemetry is disabled and microburst anomaly is enabled, then Nexus Dashboard Insights displays no Estimated Impact for that anomaly.
-
Flows that are contributing or impacted by microburst.
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. |
