Application usage analytics

January 8, 2024

Contributed by:

Application owners must have the ability to evaluate and visualize the complete application from the perspectives of performance and usage.

The improvised App Dashboard enables you to view all the application performances and usage metrics together. When you click an application, apart from the existing application performance metrics, the Web Insight tab displays the metrics details that help you:

Understand your application usage.
Correlate any performance deviations with the usage metrics.
Note
- Starting from 14.1-1.16 or later release, when you drill down a metric, the analytics view in the time series graph displays nil values (for example, 0 ms and 0 request) for the selected duration. Earlier, if there was no traffic or transaction received for the selected duration, the analytics view displayed the graphs by skipping those nil values.
- For each metric, you can view options that indicate maximum value and total value. For example:
  - - The maximum client network latency for the selected duration. Consider that you have the network latency for client 1 = 30 ms, client 2 = 15 ms, and client 3 = 3 ms. In this scenario, the Client Network Latency displays 30 ms.
  - - The total bandwidth consumed across all available clients/servers for the selected duration. Consider that you have the bandwidth consumption for client 1 = 30 MB, Client 2 = 45 MB, Client 3 = 40 MB. In this scenario, the Bandwidth displays (30 MB + 45 MB + 40 MB) = 115 MB.

The following are the metrics you can view from the Web Insight tab for the selected duration:

Application Summary - Displays an overview of the application metrics.
- Requests – Displays the total requests received by the application. The Requests tab shows the graph view for the total requests and the top 5 client requests. You can use the toggle option to customize the view.
- Bandwidth – Displays the total bandwidth processed by the application. The Bandwidth tab shows the graph view for the total bandwidth and the top 5 servers bandwidth. You can use the toggle option to customize the view.
- Response Time – Displays the average response time from the application. The Request Time tab shows the graph view of the response time breakdown and client latency, server latency, and server processing time for the selected duration. You can use the toggle option to customize the view.
- Client Network Latency – Displays the average latency from the client. The Client Network Latency tab shows the graph view of the latency breakdown for the selected duration.
- Server Network Latency – Displays the average latency from the server. The Server Network Latency tab shows the graph view of the latency breakdown for the selected duration.
- Server Processing Time – Displays the average processing time from the server. The Server Processing Time tab shows the graph view of the processing time breakdown for the selected duration.
  
  The Summary tab enables you to visualize the correlation between the requests, bandwidth, and response time in graph view.
