#3131

pika3.5中该bug复现

原因分析

慢日志明确给出了 210 µs 的耗时,而 info all # Commandstats 对应的 usec_per_call 只有 0.21,这一千倍的差距说明统计值在输出前被 /1000 误换算成了毫秒,因此当前版本的 Commandstats 单位实际上是毫秒,符合 issue #3131 的描述。

修改位置

在 src/pika_admin.cc 中将 MethodofCommandStatistics 与 MethodofTotalTimeCalculation 里把 time_consuming / 1000.0 直接改为 static_cast(time_consuming),去掉这一步除法即可恢复为真正的微秒单位,重新编译后 info all 中的 usec 与 usec_per_call 将与 slowlog 完全一致。

修复后截图

Warning

Rate limit exceeded

@github-actions[bot] has exceeded the limit for the number of commits or files that can be reviewed per hour. Please wait 25 minutes and 58 seconds before requesting another review.

⌛ How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Please see our FAQ for further information.
