About Network Trends and Insights

Cisco AI Network Analytics uses machine learning algorithms and AI techniques to provide the following:

Trends and Insights: Determine global patterns (trends) and deviations to provide system-generated insights.
AP Performance Advisories: Detect APs that have a consistently poor client experience, and provide a root cause and suggested actions.
Comparative Analytics, which includes:
- AI-Driven AP Comparisons in Network Heatmaps: Compare all of the APs in your network for a given month in a heatmap to spot trends and gain insights.
- AI-Driven Peer Comparisons: Determine how your network is performing in comparison to your peer networks for a selected Key Performance Indicator (KPI).
- AI-Driven Network Comparisons: View, compare, and identify performance improvement opportunities for objects in your network (buildings, AP model families, wireless endpoints) across selected KPIs.

View Wireless Access Point Performance Advisories

Cisco AI Network Analytics uses machine learning algorithms to identify wireless APs with a potentially poor client experience. APs are continually analyzed over long periods and those suspected of providing a suboptimal client experience are grouped by underlying root cause and suggested improvements. Insights are generated, which consist of a set of radio and network features that can be used to diagnose any underlying issue that can be rectified. Insights have the following main components:

Discover underperforming APs via various client experience KPIs.
Find appropriate features that can discriminate between APs with a poor or good client experience that is both significant and actionable by the customer as a basis of root-cause analysis (RCA).

APs are analyzed on separate frequency bands of 2.4 GHz, 5 GHz and 6GHz. Poor client experience is detected using statistical analysis of different KPIs, such as SNR, RSSI, link speed, packet retries, and packet failures.

Use this procedure to view AP performance advisories that highlight the most active APs with poor client experience based on analysis of four weeks of data.

View Network Trends and Obtain Insights

Trends are long-term evolutions of behavior in your network observed over a time period. These trends provide insights about the performance of your network (represented in beeswarm charts). The following types of insights are provided:

Intra-Site: Cisco AI Network Analytics looks into a single site or building and highlights the outlier device only within that building. In this case, the entity in the beeswarm chart is a radio and it is represented by a circle.
Inter-Site: Cisco AI Network Analytics looks at the global network and identifies an outlier building with respect to the selected KPI. In this case, the entity in the beeswarm chart is a building and it is represented by a polygon.

Use this procedure to view trends in your network.

Procedure

Step 1

Click the menu icon () and choose Assurance > Trends and Insights > Trend Deviations.

The Network Insights window appears with filters: Capacity, Coverage, and Throughput. Click the appropriate filter to refresh the data in the table. The Capacity filter is selected by default.

Note

The filters are dynamic. If there are no insights available for a filter, that filter is not displayed.

Weekly Client Load

Client load per week.

Troubleshoot

Provides links that allow you to troubleshoot and fix the trend before it becomes a critical issue:

Network Heatmap opens the heatmap and provides information about the AP or building that is highlighted in the beeswarm chart. The heatmap that displays is for the specific month in which the trend was observed.
- Intra-Site: The heatmap launches with the specific AP highlighted and prioritized in the list.
- Inter-Site: The heatmap launches with the filtered view of the APs in the building (site).

Chart

The beeswarm chart displays the performance of the client devices in your network in a 4-day (daily insights) and week (weekly insights) time interval as shown in the following figure. If there is a systematic deviation of network behavior over a time period, that trend is displayed by arrows in the chart.

Note

Each circle in the beeswarm chart represents the following:
- Intra-Site: The circle represents a radio.
- Inter-Site: The polygon represents a building.
The size of the circle represents the number of clients in the AP. A small circle has a lower client count; a large circle has a higher client count.

Step 3

Hover your cursor over a circle in the chart for information, such as the name and MAC address of the AP, the band frequency, the AP group, the location of the AP, issue count, client count, and the KPI value.

Note

For Global sites, when you hover your cursor over a circle in the chart, you see information about the building in which the trend was observed and the client count.

Compare Access Points and Switches in Network Heatmaps

Use the Network Heatmap to visually compare all of the APs in your network for a given month to spot trends and gain insights. You can choose to compare APs across different KPIs and band frequencies. The insights you gain provide information about the most congested KPIs, the most congested APs, and within those APs, which APs are being used. This information allows you to further drill down to the site or building in which the trend has been observed. After you have pinpointed your AP or a group of APs, you can determine how those APs are behaving historically: per day, per week, and during the entire month.
