Downloading and Installing NIR Application in DCNM

See the Cisco Network Insights – Resources Application for DCNM User Guide for information and procedures on downloading and installing the NIR application.

Cisco Network Insights for Resources

The Network Insights for Resources (NIR) application provides a way to gather resource information through data collection to get an overview of available resources and their active processes and configurations across the entire Cisco DCNM.

The Cisco NIR application consists of the following components:

■ Data Collection—The streaming of telemetry data is done by using software or hardware agents in the fabric devices. 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 devices 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 2.0.1 release supports only software streaming telemetry.

■ Resource and Environmental Utilization—Resource analytics supports configuration, operational and hardware resources. Environmental covers CPU, memory, temperature, and fan speed, storage, power, and DOM levels related to the leaf switches. System analytics also covers, Anomalies, and trending information of each resource and graphing of parameters which help Network operators to debug over periods of time.

■ Predictive Analytics and Correlation—The value-add of this platform is predicting failures in the fabric and correlating internal fabric failures to the user-visible/interested failures.
