Our retry logic was collecting data and then deleting it

说明与用途

记录重试次数日志揭示了逐步恶化和近乎失败的情况，之前被绿色日志掩盖。

问题

Retry loops erased evidence of retries, making it impossible to detect gradual degradation or near‑miss failures in unattended runs.

结果

By persisting retry counts, the team gained visibility into performance degradation and near‑miss failures, allowing proactive maintenance before failures occurred.

工作流

• 1. Modify retry loop to record each attempt count. 2. Append attempt count to log entry regardless of success. 3. Store both outcome and attempt count. 4. Update monitoring to analyze attempt counts for trend detection. 5. Adjust alerting to flag high retry rates rather than only failures.

证据

We built ours to solve a problem, not to report one, and for months it did exactly what we asked: it caught a failure, waited, tried again, and got through.

The fix is not clever. Count the attempts, write the count next to the outcome, and keep the count even when the outcome is good.
