About Site Analytics
Site Analytics provides you with visibility for network troubleshooting and allows you to drill down to the most problematic site, building, and floor or AP. You can set thresholds for KPIs and monitor the trend per KPI before the issue occurs.
You can define KPI thresholds that can be used to inform you of network-wide issues. Based on a KPI value, you can determine the site with the worst performance and drill down to the specific building and floor to find the problem. You can analyze issues pertaining to onboarding attempts, onboarding duration, roaming attempts, roaming duration, coverage, and connection speed.
The Site Analytics window helps you answer the following questions when investigating performance issues:
-
What: Use the KPIs to find out more about a problem. The KPI cards display the name of the KPI, the success rate of the KPI, and the name and score of the worst performer. If a KPI threshold is being met, the KPI score is shown in black. If the percentage is less than the threshold value, the score is shown in red.
The following categories are available:
-
Onboarding Attempts: Measures the percentage of wireless clients that are able to successfully onboard to an AP in the given site. An SLA is met when a wireless client successfully joins the network, and an SLA is a failure when a wireless client doesn't successfully join the network. For example, 100 clients attempt to onboard to the network. 50 clients onboard successfully, and 50 fail to onboard. The Onboarding Attempts KPI value is 50%.
-
Onboarding Duration: Measures the percentage of successfully onboarded wireless clients that are able to onboard to an AP within the configured threshold time. If a wireless client fails to onboard, it is not counted in the metric. If a wireless client successfully onboards, but takes longer than the configured SLA duration, it is counted as a failure. For example, out of the 50 clients who onboarded successfully, 30 clients took less than 10 seconds, and 20 clients took more than 10 seconds. So, the Onboarding Duration KPI value is 60%.
-
Roaming Attempts: Measures the percentage of wireless clients that are able to successfully roam from one AP to another AP in the given site. An SLA is met when a wireless client successfully roams and joins the network via another AP, and is considered a failure when the wireless client doesn't successfully join the network. For example, 100 clients attempted to roam in a given duration. 50 clients roamed successfully, and 50 failed to roam. The Roaming Attempts KPI value is 50%.
-
Roaming Duration: Measures the percentage of wireless clients that are able to successfully roam from one AP to another AP within the configured threshold time. If a wireless client fails to roam successfully, it is not counted in this metric. If a wireless client successfully roams, but takes longer than the configured threshold for roaming duration, it is counted as a failure. For example, out of the 50 clients who roamed successfully, 30 clients took less than 10 seconds, and 20 clients took more than 10 seconds. The Roaming Duration KPI value is 60%.
-
Connection Speed: Measures the percentage of time that wireless clients have data traffic with over-the-air data rates that are higher than the configured threshold rate. For example, among the data rates sampled by the controller for the 50 successfully onboarded clients, 200 samples were higher than the threshold of 11 Mbps and 50 samples were lower. The Connection Speed KPI value is 80%.
-
Coverage: Measures the percentage of time that wireless clients have data traffic with RSSI values that are higher than the configured threshold value. For example, among the RSSI values of the 50 successfully onboarded clients sampled by the controller, 200 samples were higher than the threshold of -72 dBm and 50 samples were lower. The Coverage KPI value is 80%.

When: Click the time-range setting (
) to specify the time period to use for the KPIs, timeline slider, and heatmap.
-
Where: Drill down from the site level to the building, floor, and device level.
-
Easily identify poor performing sites and buildings and their corresponding KPI values by their red or green color in the heatmap. Green indicates that the KPI threshold is being met, and red indicates that the KPI is not being met.
-
Drill down to the building level, where you can see several key factors that have contributed to the low KPI score.
-
View access points in a floor heatmap that shows their health status and device details.
-
View a list of access points on a given floor along with each access point's specific KPI score and client count.
-
Click an access point to display its Device 360 window.

The Site Analytics dashboard is available from the Assurance health dashboard AI Analytics menu option.
The AI Analytics menu option also provides access to AI Network Analytics tools. For information about these tools, see Observe Network Trends and Gain Insights.
