Service deployment profile simplification

When you start the Nexus Dashboard Insights service, the deployment profile is now automatically selected based on the intent defined in the in the Network Scale area of Cluster Configuration in Nexus Dashboard.

VMware vCenter integration

Add VMware vCenter integration to collect data and metrics of the virtual machines and hosts monitored by VMware vCenter.

Nexus Dashboard Orchestrator integration

You can see anomalies specific to the Orchestrator service assurance, raise anomalies for inconsistencies across sites, see aggregated anomalies and more.

Explore for Nexus Dashboard Orchestrator assurance

You can explore site-to-site connectivity.

Syslog support

We support the export of anomalies and advisories in syslog format.

Metadata update support for air-gap environment

With metadata support for air-gap environment, if Nexus Dashboard is not connected to Cisco secure cloud, you can upload the latest metadata to Nexus Dashboard Insights periodically in a secure and trusted way.

Software and Hardware conformance dashboard

In the Software and Hardware Conformance dashboard you can view the status of the overall software and hardware conformance inventory for a site.

Firmware update analysis for data collection type Upload File

The offline script collects additional information from Cisco APIC which is required for firmware update analysis for offline sites when the required arguments are specified.

L4-L7 traffic path visibility

You have expanded visibility in the Flow Path to L4-L7 external devices such as firewalls.

Pre-Change Analysis file-size scale change

The maximum change file size, to run a Pre-Change Analysis job, has increased.

View compliance requirement

You can view details of the associated Compliance Requirement by choosing an integrated compliance-specific anomaly.

Check code for anomalies

You can filter anomalies by check code and the results are displayed in the anomalies table.

Column customizations

You can use the Customize Columns feature in tables to customize your table columns so that the settings persist during the login instance and subsequent logins.

Multi-Site traffic path

BETA FEATURE: You can stitch together flows from across two different sites in a Site Group into one single view.

Advisory metadata updates

Biweekly advisory metadata update is now available.
