erroranalysis
In the fields of software quality assurance and fault troubleshooting, Error Analysis is a specialized diagnostic technology for "exceptions, errors, and crashes occurring during application operation". Its core functions focus on "quick error capture, error scene restoration, root cause location, and recurrence prevention", covering the entire process from "error discovery" to "problem resolution". Specific functions include: error capture and classification; complete restoration of error scenes; error trend monitoring, etc.
Usage Scenarios
- Emergency Fault Troubleshooting in Production Environment: A large number of errors (error rate > 10%) suddenly occur in core business interfaces (such as user login, order payment), and users report abnormalities. It is necessary to locate and fix the problem within minutes to avoid business losses.
- Diagnosis of Intermittent/Low-Frequency Errors: Errors occur infrequently (e.g., once a day) and irregularly (not triggered at fixed times). Logs only record the "error type" (such as "NullPointerException") without detailed context, making manual troubleshooting and reproduction difficult.
- Long-Term Error Management: The application has a large number of "high-frequency but low-risk errors" (such as "occasional timeout of the log interface with an error rate of 0.5%, which does not affect core business"). If left unhandled for a long time, these errors may accumulate into serious problems (e.g., "the error rate of the log interface gradually rises to 5%, occupying thread pool resources and causing delays in other interfaces").
Get Started
-
Navigate to the System Services -> Error Analysis page. Here, you can view error statistics and classified data, and support drilling down to jump to error details, etc.
- Error request trends: You can view the trends of successful requests, error requests, and error rates.
- Errors: Statistics on the trends of error HTTP statuses.
- The error list supports quick switching of statistical dimensions (e.g., viewing errors by error cause, service, service instance, and interface dimensions) to quickly find entities with a high error proportion.
-
To view specific errors, enter the error details page. From the request address, entry point, and the host where the instance is located, you can view detailed error logs and call chains. This helps you quickly locate the position of the error instance and the cause of the error.
-
The error details support quick jumps to the host where the service is located and viewing of error logs.
