Cisco Nexus Insights Installation and Setup
About Cisco Nexus Insights
Cisco Nexus Insights ( Cisco NI ) is a real-time monitoring and analytics application.
Cisco Nexus Insights Components
The Cisco Nexus Insights (Cisco NI) application monitors a data center network and pinpoints issues
that can be addressed to maintain availability and reduce surprise outages. Cisco NI’s
understanding of your network allows it to provide proactive advice with a focus on maintaining
availability and alerting customers about potential issues that can impact up-time.
The Cisco NI app provides log collection functionalities which are useful when working with Cisco
TAC. It provides a way for Cisco customers to collect tech support across multiple devices and
upload those tech supports to Cisco Intersight Cloud. Additionally, it enables capability for Cisco TAC
teams to collect technical support on demand for a particular device.
Cisco NI app consists of the following components:
Data Management—Settings to configure flows and schedule jobs to collect software telemetry
and flow telemetry data.
Flow Configuration—Manage flow configuration rules on the site enabled on Cisco NI app.
Collection Status—Displays the node capabilities and collection status of the nodes for the
features that are supported and not supported.
Bug Scan—Provides access to configure, schedule, on-demand bug scan that runs for a
selected site. Bug Scan generates system anomalies and alerts that are critical for a
particular node on the site.
Third Party Integrations—Provides access to onboard a AppDynamics Controller on to the
Cisco NI app.
Export Data—Streams the data collected from Cisco NI app through a Kafka exporter to send
the summary of data in Cisco NI app email.
Devices—Provides various ways of viewing the behavior of the nodes based on Resource
Utilization, Environmental, Statistics, End Point Analytics, and Flow Analytics.
Analyze Alerts—Access to total advisories, notices, PSIRTs, hardware, software, and hardening
check advisories applicable to your network.
Advisories
Field Notices—Notices such as end-of-life notices for switch hardware and software.
7
PSIRTs—Product Security Incident Response Team notices that display three levels of
advisory severity for switch hardware and software in your network.
Firmware Upgrade Path and Upgrade Impact—To upgrade to a recommended software
version, Cisco NI app suggests an upgrade path and determines the potential impact of
the upgrade to the first-hop.
Anomalies
Bug Scan—Provides access to configure and schedule bug scan that runs for a selected
site.
Troubleshoot
Log Collection—Collect and upload the logs for devices in your network to Cisco
Intersight Cloud. Enables Cisco TAC to trigger on-demand collection of logs for user
devices on the site and pull the logs from Cisco Intersight Cloud.
Data Collection—The streaming of telemetry data is done by the Operating Systems on the site
nodes. As each data source is different and the format in which data is streamed is different,
there are corresponding collectors running analytics that translate the telemetry events from
the nodes into data records to be stored in the data lake. The data stored in the data lake is a
format that the analytics pipeline can understand and work upon.
The following telemetry information collected from various nodes in the site to achieve the
goal:
Resources Analytics—This includes monitoring software and hardware resources of site
nodes on the Cisco APIC.
Environmental—This includes monitoring environmental statistics of hardware resources
such as fan, CPU, memory, and power of the site nodes.
Statistics Analytics—This includes monitoring of nodes, interfaces, and protocols on the
Cisco APIC and site nodes.
Flow Analytics—This includes monitoring of flows on the Cisco site nodes, detecting average
latency, packet drop indication, and flow move indication across the entire Cisco ACI.
Endpoint Analytics—This includes monitoring endpoints on the Cisco site nodes for rapid
endpoint moves and endpoints that do not get learnt back after a reboot across the entire
Cisco ACI.
Event Analytics—This includes monitoring of events, faults and configuration changes.
Resource Utilization and Environmental Statistics—Resource analytics supports configuration,
operational, and hardware resources. Environmental covers CPU, memory, temperature, fan
utilization, power, and storage related to the leaf nodes, spine nodes, and Cisco APIC. System
analytics also covers anomalies, the trending information of each resource, and graphing of
parameters, which help network operators debug nodes over periods of time.
Predictive Analytics and Correlation—The value-add of this platform is predicting failures in the
site and correlating internal site failures to the user-visible or interested failures.
Anomaly Detection—Involves understanding the behavior of each component using different
machine learning algorithms and raising anomalies when the resource behavior deviates from
the expected pattern. Anomaly detector applications use different supervised and unsupervised
8
learning algorithms to detect the anomalies in the resources and they log the anomalies in an
anomaly database.

11
The Multi-Site setup enables you to onboard the site. Click Edit Configuration for a list of sites,
status, and flow analytics status. The site status is disabled by default.
The Early Access Mode allows you to enable beta Nexus Insights features and enhancements. Once
the beta features are enabled, they cannot be disabled.
Cisco NI Multi-Site Setup
The Multi-Site and flow configuration enables you to enable or onboard the site from the list of
available sites on Cisco NI.
1. Click Settings > Nexus Insights Setup > Edit Configuration for a list of sites, status, enable,
and disable sites. The site status is disabled by default. The Nexus Insights Setup - Multi-Site
Configuration page displays the list of sites that were added to the node.
2. From the SW Analytics drop-down menu, choose Enable to apply streaming policies onto the
site and onboard the site.
3. From the Flow Analytics drop-down menu, choose Enable to enable flow telemetry
configuration for that site.
When you disable or offboard a site, the site status is then disabled and flow analytics is
automatically disabled.
You can choose to enable software telemetry and flow telemetry per site. See Flow Rules
Configuration to configure flow rules.
4. From the Microbrust Sensitivity drop-down menu, choose Enable to enable the micro-burst
status for the site. The status is disabled by default.
Based on the percentage of threshold, micro-burst is either low, high, or medium.
The percentage of threshold is inverse to sensitivity. When the number of micro-bursts are greater
than 100 on a particular interface, an anomaly is raised.
Cisco NI app collects the micro-burst data for the selected sites. Micro-burst anomalies are raised on
the interface of the node. See Micro-Burst Support for Interface Statistics for details.
