BlazeMeter’s failure analysis report is a powerful tool for identifying and rectifying issues. It provides detailed information about failed requests, enabling pinpointing of problematic areas. To utilize it effectively, start by examining the ‘Errors Over Time’ graph to identify when failures occurred. This can help correlate errors with specific test events.
Next, review the ‘Error Breakdown’ section which categorizes errors based on their HTTP response codes. This helps in understanding the nature of the problem – whether it’s client-side (4xx) or server-side (5xx).
The ‘Top Errors’ table gives insight into the most frequent errors. By clicking on each error, you can view its details including request headers, response body, and stack trace. This aids in diagnosing the root cause.
To rectify issues, use this data to make necessary adjustments in your application or environment. For instance, if there are many 500 errors, investigate server logs for exceptions. If there are numerous 404 errors, check if URLs or resources have been moved or deleted.
