Aruba Utilities includes a number of tools for monitoring and troubleshooting wireless LANs from HPE Aruba Networking. Some tools work with any WLAN, others are clients for specific Aruba APIs. Support is through email to the developer, or via the HPE Aruba Networking Community site http://community.arubanetworks.com/t5/Aruba-Apps/bd-p/Aruba-Apps A user guide is available http://community.arubanetworks.com/t5/Aruba-Apps/Aruba-Utilities-user-guide/td-p/246783 Aruba Utilities includes: • A Wi-Fi Monitor showing the Wi-Fi environment, including the current access point, RF channels, RSSI measurements and up/down PHY rates, other access points audible to the device and handover events. AP names are displayed (when configured on the AP, of course). • A Telnet/SSH client that works with Aruba devices, allowing network configuration and monitoring from a mobile platform. • An AirWave client that downloads the floorplan image and AP details from the network’s management system. See where APs are located relative to your position, and touch AP icons for details of current loading, channels and power. Also an estimated heatmap and a site survey function that links actual coverage measurements to locations on the floorplan. • A Central API client. Central is quite tricky to set up on a phone screen, as the Ids and tokens are long, and need to be copy-pasted into the app. I'm still working on a good way of driving JSON queries from the phone UI. • The Device tab shows information including Wi-Fi, IP, DHCP, cellular status. • Measurements are written to a plain-text log file and various csv report files that can be emailed - you address the email - for use later. • A Bluetooth Low Energy (BLE) scan reports nearby iBeacons, Aruba beacons and other BLE devices with UUID, index values and signal strength measurements. Also the BluConsole function. • CBRS is a window into the cellular side of the phone. It's useful for public and private 4G network troubleshooting. • Ranging is an FTM/802.11mc/rtt client, giving distance measurements when used with FTM-enabled access points. • Android versions of iPerf, Ping, DNS and mDNS provide network testing functionality. • The multi-SSH tab offers side-by-side telnet windows for managing multiple devices simultaneously: needs a big screen, most useful on a tablet. • The ALE client tab exercises the Analytics and Location Engine. Aruba Utilities was developed by the CTO Group in HPE Aruba Networking as a testbed for our research into WLAN measurement and optimization techniques. It will be of interest to network engineers with multi-AP WLANS, especially Aruba WLANs.
