A diagnostic report summarizes the data that is collected by browser monitoring in a period of time. The report analyzes and displays the website performance based on JavaScript (JS) error logs, the success rate of API requests, and the page loading speed. This helps you understand the key monitoring metrics for websites and resolve issues.
Procedure
-
Log on to the ARMS console. In the left-side navigation pane, choose .
-
On the Browser Monitoring page, select a region in the top navigation bar and click the name of the application that you want to manage.
- In the upper-right corner of the page, click Quick Diagnostics.
- The Diagnostic Report page opens, displaying the report.
JS error logs
This section analyzes JS errors by tracking page views (PVs), which are categorized as error, exception, or normal. The data is then aggregated by page to generate diagnostic results (JS error rate = Error PVs / Total PVs). The diagnostic results include error counts, the page's share of total errors, and the number of new errors.
The Diagnostic Report page displays a table of analyzed pages with columns for Page, Diagnostic result, and Actions. In the Actions column, click View Details to see diagnostic information for a specific page.API success rate
This section analyzes API performance by counting the number of failed, abnormal, and successful calls. Data is then aggregated by API to generate diagnostic results (API success rate = Number of successful API calls / Total number of API calls). These results highlight issues such as a low success rate or a sudden drop in success rate, and report average and minimum values.
The Diagnostic Report page displays a table of analyzed APIs with columns for API, Diagnostic result, and Actions. In the Actions column, click View Details to see diagnostic information for a specific API.Page loading speed
This section tracks performance on a per-page basis, counting the number of successful, failed, and abnormal page loads. Data is aggregated by page to generate diagnostic results based on the first paint time. The results highlight rendering performance issues, such as slow first paint times. They also include average and peak values, along with the times when those peaks occurred.
Results are categorized into two levels: Very Slow (first paint time > 5600 ms) and Slow (2400 ms < first paint time < 5600 ms). Click View Details to see detailed diagnostic information for the corresponding page.
