Application usage analytics

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, alongside 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 14.1-4.x 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 = 644 ms, client 2 = 15 ms, and client 3 = 3 ms. In this scenario, the Client Network Latency displays 644 ms.

  • - The total bandwidth consumed across all available clients/servers for the selected duration. Consider that you have the bandwidth consumption for client 1 = 79.54 MB, Client 2 = 45 MB, Client 3 = 40 MB. In this scenario, the Bandwidth displays (79.54 MB + 45 MB + 40 MB) = 164.54 MB.

The following are the Web Insight metrics that you can view from the Usage tab:
