5 NetVisor UNUM High Capacity User Guide: 2022.6.3.2
Introduction (cont'd)
Arista NetVisor UNUM enables the network administrator to extract analytical value from the telemetry
data reported by the network switches powered by the NetVisor OS network operating system.
Once data is collected, Arista NetVisor UNUM relies upon a modern search engine database infrastructure
to store, aggregate, filter, correlate and visualize vast amounts of data in real-time as well as with a powerful
time machine functionality.
The Arista NetVisor UNUM portal provides a collection of feature-rich applications that manages and
orchestrates the gathering and presentation of network analytics using various types of collectors and
reporting software.
The UNUM applications rely primarily on features of the NetVisor OS, such as vFLOWs, mirrors, and
connections statistics, and can also provide analytics in a non-Arista environment.
At a high-level, Arista NetVisor UNUM supports the following deployment scenarios:
·
NetVisor OS as a mirror switch; an out-of-band switch is configured as a mirror in either an existing
Arista-switched network or a non-Arista-switched network.
·
NetVisor OS as an inband switch; stats are pulled directly from configured switches such as
connections, vports, ports, tunnels and, vflow-stats.
·
Collectors gather network analytics and feed data into the Arista NetVisor UNUM analytics store(s):
§The Collector uses the vREST API to gather the analytics data from NetVisor OS.
