Unique Connected Clients Graph

The Unique Connected Clients graph displays the range of clients attempting to connect to the network. You can modify the range (dark gray area) of clients by moving the scroll bar and this automatically changes the trends displayed in the Overview, Connection, Performance, and Infrastructure tabs. Pausing the pointer over the graph or placing the pointer at a particular point provides information about the number of connected clients at a time on a given day.

You can also select the drop-down arrows on the colored bars - Successful Connections, Failed Connections and Connection Success Ratio to display the Connection Failures tile. It displays probable reasons for the client to disconnect from the network such as RADIUS failure, EAP failure, DHCP failure and so on. This information is displayed as a bar chart showing the failure percentage in each phase. Clicking the failure types displays more information as a pie chart and table. The pie chart displays the Top 5 Impacted Zones and Top 5 Impacted WLANs. The table displays Top 100 Impacted Clients detailing information such as the client MAC address, manufacturer information, SSID, username, hostname, links to the Client Details page and Client Troubleshooting page for further analysis.

Similarly, you can also select the drop-down arrow on the Avg. Time To Connect bar to display the Avg. Time To Connect tile. It displays the average time taken by the client to connect to the network through various authentication mechanisms such as 802.11 authentication, RADIUS authentication, DHCP authentication and so on. This information is displayed as a bar chart showing the percentage of time in each phase of connection. Clicking the authentication types displays more information as a pie chart and table. The pie chart displays the Top 5 Impacted Zones and Top 5 Impacted WLANs. The table displays Top 100 Impacted Clients detailing information such as the client MAC address, manufacturer information, SSID, username, hostname, links to the Client Details page and Client Troubleshooting page for further analysis.

Overview Tab

The Overview tab displays information about successful client connections, time taken by the client to connect to the network, client throughput, AP capacity, and AP service uptime. The area is graphically divided into three sections: a pill-shaped box depicting the metric as percentages, a time series graph depicting the metric as percentages, and a histogram.

The pill-shaped box not only depicts the percentage of successful connections, but also specifies the connections, sessions, and APs meeting a threshold within the larger sample set.

There are two types of histograms: a view-only histogram that provides information about the threshold trends, and another configurable histogram that allows you to set the threshold for a metric. The threshold you set for the metric is the value against the goal. By default, the goal met for the last 7 days is displayed. Click Apply to set the new threshold for the metric or click Reset to revert to the default threshold value.

The following KPIs are displayed on the tab:

• Connection Success: Measures the number of connection attempts that complete successfully. A connection is deemed successful when a Wi-Fi client is able to complete the 802.11 authentication, association, L2 authentication, and receives an IP address from the DHCP. If any of these stages fail, it is considered as a failed connection. For L3 authentication such as WISPr and captive portal authentication, since the WiFi client receives an IP address before the L3 authentication, the client connection is deemed successful before the L3 authentication completes.

  The time-series graph on the left displays the percentage of successful connections across time, and the bar chart on the right captures the daily percentage over the last seven days of the selected time range. Note that the numbers related to the time-series will change as you zoom-in or zoom-out of a time range, whereas the bar chart remains fixed based on the time range selected at the top of the page.

• Time to Connect (TTC): Measures the total time taken for a WiFi client to successfully go through all the required stages in order to establish an IP connection, namely 802.11 authentication, association, L2 authentication, and receiving an IP address from the DHCP.

  The time-series graph on the left displays the percentage of successful connections across time, that meet the configured TTC SLA. Bar chart on the right displays the distribution of TTC. Note that the numbers related to the time-series will change as you zoom-in or zoom-out of a time range, whereas the bar chart remains fixed based on the time range selected at the top of the page.

Note that the numbers related to the time-series will change as you zoom-in or zoom-out of a time range, whereas the bar chart remains fixed based on the time range selected at the top of the page.

• Online APs: Measures the percentage of APs which are online and connected to Smart Zone.

  The time-series graph on the left displays the Online AP percentage across time. The bar chart on the right captures the daily Online AP percentage over the last seven days of the selected time range. Note that the numbers related to the time-series will change as you zoom-in or zoom-out of a time range, whereas the bar chart remains fixed based on the time range selected at the top of the page.

Connection Tab

The Connection tab displays information about successful client connections, time taken by the client to connect to the network, association, user authentication, DHCP, RADIUS, and roaming success. The area is graphically divided into three sections: a pill-shaped box depicting the metric as percentages, a time series graph depicting the metric as percentages, and a histogram.

The pill-shaped box not only depicts the percentage of successful connections, authentications, and associations, but also specifies the connections, authentications, and associations meeting a threshold within the larger sample set.

There are two types of histograms: a view-only histogram that provides information about the threshold trends, and another configurable histogram that allows you to set the threshold for a metric. The threshold you set for the metric is the value against the goal. By default, the goal met for the last 7 days is displayed. Click Apply to set the new threshold for the metric or click Reset to revert to the default threshold value.
