AWS CloudWatch 推出了秒級的記錄功能：「New – High-Resolution Custom Metrics and Alarms for Amazon CloudWatch」。
從一分鐘變成一秒鐘讓之後的調整以及 debug 好用很多... 不過這次支援秒級的是 custom metrics，原先 AWS 自家服務的支援不在這次範圍：
Today we are adding support for high-resolution custom metrics, with plans to add support for AWS services over time. Your applications can now publish metrics to CloudWatch with 1-second resolution.
另外 alarm 的時間可以降到十秒：
You can watch the metrics scroll across your screen seconds after they are published and you can set up high-resolution CloudWatch Alarms that evaluate as frequently as every 10 seconds.
