Health Page

The Health page provides information about network health by giving insights about key performance indicators (KPIs) of the network. The information provided by the Health page allows you to analyze the network health and behavior in real time..

You can evaluate network health based on a variety of thresholds that you are allowed to set, called goals. For example, you can set the goal (or threshold) to five seconds for all clients to connect to the network, and confirm the number of clients accomplishing the five-second goal in real time. You can thereby determine the metric to understand the number of clients that connect within or before time, and the ones that are delayed. The success rate of network elements meeting each of the goals is typically displayed as a percentage of the metric.

At a high level, the Health page also displays the number of connection attempts, successful connections, failed connections, the connection status, and the average time to connect.

Note: You can only view and manage network data for the domains to which you have access,, based on the resource group creation and the role assigned to you as a user. For more information, refer to Managing Users and Managing Resource Groups.

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 grey 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.

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. Pausing the pointer over the time series graph at a point displays the percentage of successful connections made and the number of connections attempted by the client at that time and date. Pausing the pointer over the histogram bar graph displays the number of sample clients that attempted to connect to the network.
  • Time to Connect (TTC): Measures the percentage of connection attempts that completed within the service level agreement (SLA). Pausing the pointer over the time series graph at a point displays the percentage of TTC count and connection count at that time and date. Pausing the pointer over the histogram bar graph displays the number of sample clients that attempted to connect to the network.
  • Client Throughput: Measures the number of client sessions with the throughput potential that met the SLA. Pausing the pointer over the time series graph at a point displays the percentage of throughput count and session count at that time and date. Pausing the pointer over the histogram bar graph displays the number of sample clients that attempted to connect to the network.
  • AP Capacity: Measures the number of APs with the average capacity that met the SLA. Pausing the pointer over the time series graph at a point displays the percentage of capacity count and AP count at that time and date. Pausing the pointer over the histogram bar graph displays the number of sample clients that attempted to connect to the network.
  • AP Service Uptime: Measures the percentage of time the radios of an AP are fully available for client service.
