HOW ARUBA NETINSIGHT WORKS

IP address, domain resolution data

Authentication data - access timeouts, portal response, etc.

AP placement data

Wi-Fi health data: airtime/client efficiency, roaming, client

Compression & security

Data extraction from multiple sources

Analysis applying Machine Learning & Aruba network expertise

Automated insights & recommendations

Intelligence from 100K-5MM APs(1MM Clients)

GOAL IS TO FIND & FIX ISSUES EASIER AND FASTER- BEFORE THEY TURN INTO BIGGER PROBLEMS

Anomaly Detection with automatic baselining of “normal” performance

Anomaly details & impact

Automatic rootcause & recommendations to fix

BEFORE AFTER

Impact Validationof network changes by closely monitoring Key Performance Metrics

• Traffic, Connectivity,SNR, Speed, Airtime Utilization/Efficiency, etc.

ENSURING YOUR CHANGES MAKE A DIFFERENCE

ANOTHER EXAMPLE: 802.1x FAILURES FOR APPLE TV’s

Problem: Apple TV’s having thousands of auth failures every day

Root Cause: Certificate validation fails on Apple TV due to incorrect system time

Solution: Connect to wired port, correct time on Apple TVs

UPLINK USAGE PER DEVICE TYPE ANOMALIES

Individual device doing BitTorrent– Uplink traffic over 7 days exceeds 1.463 GB

– Device classification: OS X

– Session breakdown by AppRF:– Large number of destination IP addresses– Traffic classified as BitTorrent

Dropbox bug on many devices– Multiple Windows devices generating 10 to 20 GB uplink traffic per day

– Caused by known bug in Dropbox client software

Deliver great experiences, preserve brand reputation

Minimize disruptions, keep the business running at its best

CUSTOMER OUTCOMES
