The Cisco Network Insights for Resources app in Cisco DCNM provides a way to gather data from third-party nodes through Cisco NIR application. The data is acquired through the third-party collector service using REST based EAPI method calls provided by the collector service.

The following telemetry information is collected from third-party nodes in the fabric:

• Environmental Statistics—This includes monitoring environmental statistics such as CPU, memory, fan, temperature, and power usage, and storage details of the fabric nodes.

• Interface Statistics—This includes monitoring of nodes, interfaces, and protocol statistics on Cisco DCNM and fabric nodes using LLDP and LACP.

• Resource Statistics—This includes monitoring software and hardware resources of fabric nodes on Cisco DCNM using IPv4 unicast, IPv4 multicast, and MAC.

The following are limitations for third-party nodes for Cisco NIR application.

• The Interface Statistics for LLDP and LACP do not support Flap Count, Entries Aged Count, and PDU Timeout Count.

• The Interface Statistics for MAC do not support local and static endpoints.

• Third-party nodes are supported only on Monitored mode.

Adding or removing the third-party nodes from the fabric will generate a control message, which triggers the third-party collector service present in the UTR pipeline to start or stop collecting data from the specific node.

To discover and enable third-party nodes to Cisco DCNM fabric:

• Create an external fabric to discover the third-party nodes, refer to Creating an External Fabric for details.

• To discover the third-party nodes, refer to Discovering New Switches for details.

• Add the third-party nodes to the external fabric, see Adding non-Nexus Devices to External Fabrics for details.
