Hello, I'm tsukuboshi (tsukuboshi0755)!
At the JAWS-UG Chiba x Tokatsu.dev Collaboration LT Event held on 2026/11/15, I gave a lightning talk titled "CloudWatch Metrics Monitoring in the New Era, Changed by OpenTelemetry"!
In this article, I'll share my presentation slides!
What is JAWS-UG Chiba?
It is an AWS user group for people who live in Chiba, have ties to Chiba, or love Chiba.
This time it was held jointly with Tokatsu.dev, and the LT event took place at Palette Kashiwa, near Kashiwa Station!

Conclusion
This time, I introduced the content of my lightning talk about the differences between Classic metrics and OpenTelemetry metrics, and how to choose the way to send OpenTelemetry metrics.
AWS standard metrics are fine to keep as Classic metrics, and for custom metrics, I recommend using OpenTelemetry metrics for any newly created ones.
As for how to send them, first decide whether to place a Collector, and if you're unsure, going through the CloudWatch agent seems like a good choice.
Please try turning on CloudWatch's OTel enrichment in a test environment first, and experience querying metrics with PromQL!
That's all from tsukuboshi (tsukuboshi0755)!
