The first time you open this window you are directed to create a network hierarchy. You
can either import an existing hierarchy or create a new one from the Manage > Planning window. (See Plan your Network). After you have created and populated your network, select a
location, building, or floor from the list to the left of the map to see data. To see
health data for your entire network, select Global View. Use the
following tools to navigate the window.
Because data is collected on an hourly basis, this window might be empty for up to
one hour. Select Where's My Data? for more information.
For large networks with multiple locations, enter the first few characters of the
location name in the type-ahead Search Maps field to
automatically bring up matching items. As you enter more characters, the search
results become more precise.
Use the Filter
section to manage the data that is displayed. When a filter is applied, the filter
icon contains a circle in the lower right corner.
Status cards across the top of the window display information about your network health.
When you select a network location, the status card data automatically changes to match
your selection. Network health is determined by several factors, including availability,
number of reboots, average CPU and memory usage, and average power consumption,
indicated by color. Green indicates excellent network health, with scores between 80 and
100. Yellow indicates good network health, with scores between 50 and 79. Red indicates
poor network health, with scores between 0-50.
Select anywhere inside a status card to see additional details. From inside
the detail panels, you can navigate directly to another status card, refresh data,
customize the time frame of the captured data display, print the details on the timeline
within the specified time frame, or download the data as a .png, .svg, .jpg, or PDF
file. Many of the following data widgets are interactive and let you drill deeper for
additional information.
Device: The Devices
Health timeline displays information about usage, clients, and health. Device
widgets display device health, current availability, hardware health, active alarms,
top device uptime, configuration and firmware status, channel change events, DFS
events, reboots and more. Many sections of the widgets are interactive. For example,
if there is a carat icon at the bottom of a widget, you can expand it for more
information.
Client:
Displays
overall and wireless health scores, bandwidth usage, issues, channel
distribution, supported spatial streams, maximum client capability in the 2.4, 5
and 6 GHz bands, association and probe requests, 802.1x technology, transmit
power, and more.
The Overall Score is
calculated by dividing the sum of the Client WiFi
Experience, Client IP Network
Experience, and Client Application
Experience health scores by three (Σ(overallWifiHealthScore +
overallNetworkHealthScore + overallApplicationHealthScore) / 3).
WiFi Health: Displays
usage, clients, and the overall Wi-Fi score over time. Widgets display
wireless health details, association per radio score, channel utilization, the SNR
score, data rates, and retries, and more.
Network Health:
Displays network health and usage. Widgets display the overall network health score,
WAN, VPN, and gateway Internet availability and latency, multicast and unicast
detection, Ethernet interface modes, and more.
Services Health:
Displays DHCP, DNS, and RADIUS activity. Widgets display the overall health score,
network and authentication services scores, DHCP DNS and NTP availability,
authentication, management, and network service availability, and more.
Applications Health:
Displays the top applications active in your wireless network. Three applications
are shown by default, but you can add an application by typing the first few letters
in the type-ahead search field, and then selecting the full name when it displays.
To delete an application, select the X in the check box
next to the application name. Charts and widgets display total usage, top 5
applications, and a table showing the top 20 or top 100 active application groups.
You can change the number of applications displayed per window on the lower left,
and scroll through the windows on the lower right.
Security Health:
Displays network activity involving rogue clients, rogue APs, and traffic
violations. Charts and widgets display a security overview, detected Layer 2 DOS
(Denial of Service) attempts, rogue APs, and traffic violations.
